GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

Smarty 3.1.11
Author: Monte Ohrt <monte at ohrt dot com >
Author: Uwe Tews
AN INTRODUCTION TO SMARTY 3
NOTICE FOR 3.1 release:
Please see the SMARTY_3.1_NOTES.txt file that comes with the distribution.
NOTICE for 3.0.5 release:
Smarty now follows the PHP error_reporting level by default. If PHP does not mask E_NOTICE and you try to access an unset template variable, you will now get an E_NOTICE warning. To revert to the old behavior:
$smarty->error_reporting = E_ALL & ~E_NOTICE;
NOTICE for 3.0 release:
IMPORTANT: Some API adjustments have been made between the RC4 and 3.0 release.
We felt it is better to make these now instead of after a 3.0 release, then have to
immediately deprecate APIs in 3.1. Online documentation has been updated
to reflect these changes. Specifically:
---- API CHANGES RC4 -> 3.0 ----
$smarty->register->*
$smarty->unregister->*
$smarty->utility->*
$samrty->cache->*
Have all been changed to local method calls such as:
$smarty->clearAllCache()
$smarty->registerFoo()
$smarty->unregisterFoo()
$smarty->testInstall()
etc.
Registration of function, block, compiler, and modifier plugins have been
consolidated under two API calls:
$smarty->registerPlugin(...)
$smarty->unregisterPlugin(...)
Registration of pre, post, output and variable filters have been
consolidated under two API calls:
$smarty->registerFilter(...)
$smarty->unregisterFilter(...)
Please refer to the online documentation for all specific changes:
http://www.smarty.net/documentation
----
The Smarty 3 API has been refactored to a syntax geared
for consistency and modularity. The Smarty 2 API syntax is still supported, but
will throw a deprecation notice. You can disable the notices, but it is highly
recommended to adjust your syntax to Smarty 3, as the Smarty 2 syntax must run
through an extra rerouting wrapper.
Basically, all Smarty methods now follow the "fooBarBaz" camel case syntax. Also,
all Smarty properties now have getters and setters. So for example, the property
$smarty->cache_dir can be set with $smarty->setCacheDir('foo/') and can be
retrieved with $smarty->getCacheDir().
Some of the Smarty 3 APIs have been revoked such as the "is*" methods that were
just duplicate functions of the now available "get*" methods.
Here is a rundown of the Smarty 3 API:
$smarty->fetch($template, $cache_id = null, $compile_id = null, $parent = null)
$smarty->display($template, $cache_id = null, $compile_id = null, $parent = null)
$smarty->isCached($template, $cache_id = null, $compile_id = null)
$smarty->createData($parent = null)
$smarty->createTemplate($template, $cache_id = null, $compile_id = null, $parent = null)
$smarty->enableSecurity()
$smarty->disableSecurity()
$smarty->setTemplateDir($template_dir)
$smarty->addTemplateDir($template_dir)
$smarty->templateExists($resource_name)
$smarty->loadPlugin($plugin_name, $check = true)
$smarty->loadFilter($type, $name)
$smarty->setExceptionHandler($handler)
$smarty->addPluginsDir($plugins_dir)
$smarty->getGlobal($varname = null)
$smarty->getRegisteredObject($name)
$smarty->getDebugTemplate()
$smarty->setDebugTemplate($tpl_name)
$smarty->assign($tpl_var, $value = null, $nocache = false)
$smarty->assignGlobal($varname, $value = null, $nocache = false)
$smarty->assignByRef($tpl_var, &$value, $nocache = false)
$smarty->append($tpl_var, $value = null, $merge = false, $nocache = false)
$smarty->appendByRef($tpl_var, &$value, $merge = false)
$smarty->clearAssign($tpl_var)

$smarty->clearAllCache($exp_time = null, $type = null)
$smarty->clearCache($template_name, $cache_id = null, $compile_id = null, $exp_time = null, $type = null)
$smarty->registerPlugin($type, $tag, $callback, $cacheable = true, $cache_attr = array())
$smarty->registerObject($object_name, $object_impl, $allowed = array(), $smarty_args = true, $block_methods = array())
$smarty->registerFilter($type, $function_name)
$smarty->registerResource($resource_type, $function_names)
$smarty->registerDefaultPluginHandler($function_name)
$smarty->registerDefaultTemplateHandler($function_name)
$smarty->unregisterPlugin($type, $tag)
$smarty->unregisterObject($object_name)
$smarty->unregisterFilter($type, $function_name)
$smarty->unregisterResource($resource_type)
$smarty->compileAllTemplates($extention = '.tpl', $force_compile = false, $time_limit = 0, $max_errors = null)
$smarty->clearCompiledTemplate($resource_name = null, $compile_id = null, $exp_time = null)
$smarty->testInstall()
// then all the getters/setters, available for all properties. Here are a few:
$caching = $smarty->getCaching(); // get $smarty->caching
$smarty->setCaching(true); // set $smarty->caching
$smarty->setDeprecationNotices(false); // set $smarty->deprecation_notices
$smarty->setCacheId($id); // set $smarty->cache_id
$debugging = $smarty->getDebugging(); // get $smarty->debugging
FILE STRUCTURE
The Smarty 3 file structure is similar to Smarty 2:
/libs/
Smarty.class.php
/libs/sysplugins/
internal.*
/libs/plugins/
function.mailto.php
modifier.escape.php
...
A lot of Smarty 3 core functionality lies in the sysplugins directory; you do
not need to change any files here. The /libs/plugins/ folder is where Smarty
plugins are located. You can add your own here, or create a separate plugin
directory, just the same as Smarty 2. You will still need to create your own
/cache/, /templates/, /templates_c/, /configs/ folders. Be sure /cache/ and
/templates_c/ are writable.
The typical way to use Smarty 3 should also look familiar:
require('Smarty.class.php');
$smarty = new Smarty;
$smarty->assign('foo','bar');
$smarty->display('index.tpl');
However, Smarty 3 works completely different on the inside. Smarty 3 is mostly
backward compatible with Smarty 2, except for the following items:
*) Smarty 3 is PHP 5 only. It will not work with PHP 4.
*) The {php} tag is disabled by default. Enable with $smarty->allow_php_tag=true.
*) Delimiters surrounded by whitespace are no longer treated as Smarty tags.
Therefore, { foo } will not compile as a tag, you must use {foo}. This change
Makes Javascript/CSS easier to work with, eliminating the need for {literal}.
This can be disabled by setting $smarty->auto_literal = false;
*) The Smarty 3 API is a bit different. Many Smarty 2 API calls are deprecated
but still work. You will want to update your calls to Smarty 3 for maximum
efficiency.
There are many things that are new to Smarty 3. Here are the notable items:
LEXER/PARSER
============
Smarty 3 now uses a lexing tokenizer for its parser/compiler. Basically, this
means Smarty has some syntax additions that make life easier such as in-template
math, shorter/intuitive function parameter options, infinite function recursion,
more accurate error handling, etc.
WHAT IS NEW IN SMARTY TEMPLATE SYNTAX
=====================================
Smarty 3 allows expressions almost anywhere. Expressions can include PHP
functions as long as they are not disabled by the security policy, object
methods and properties, etc. The {math} plugin is no longer necessary but
is still supported for BC.
Examples:
{$x+$y} will output the sum of x and y.
{$foo = strlen($bar)} function in assignment
{assign var=foo value= $x+$y} in attributes
{$foo = myfunct( ($x+$y)*3 )} as function parameter
{$foo[$x+3]} as array index
Smarty tags can be used as values within other tags.
Example: {$foo={counter}+3}
Smarty tags can also be used inside double quoted strings.
Example: {$foo="this is message {counter}"}
You can define arrays within templates.
Examples:
{assign var=foo value=[1,2,3]}
{assign var=foo value=['y'=>'yellow','b'=>'blue']}
Arrays can be nested.
{assign var=foo value=[1,[9,8],3]}
There is a new short syntax supported for assigning variables.
Example: {$foo=$bar+2}
You can assign a value to a specific array element. If the variable exists but
is not an array, it is converted to an array before the new values are assigned.
Examples:
{$foo['bar']=1}
{$foo['bar']['blar']=1}
You can append values to an array. If the variable exists but is not an array,
it is converted to an array before the new values are assigned.
Example: {$foo[]=1}
You can use a PHP-like syntax for accessing array elements, as well as the
original "dot" notation.
Examples:
{$foo[1]} normal access
{$foo['bar']}
{$foo['bar'][1]}
{$foo[$x+$x]} index may contain any expression
{$foo[$bar[1]]} nested index
{$foo[section_name]} smarty section access, not array access!
The original "dot" notation stays, and with improvements.
Examples:
{$foo.a.b.c} => $foo['a']['b']['c']
{$foo.a.$b.c} => $foo['a'][$b]['c'] with variable index
{$foo.a.{$b+4}.c} => $foo['a'][$b+4]['c'] with expression as index
{$foo.a.{$b.c}} => $foo['a'][$b['c']] with nested index
note that { and } are used to address ambiguties when nesting the dot syntax.
Variable names themselves can be variable and contain expressions.
Examples:
$foo normal variable
$foo_{$bar} variable name containing other variable
$foo_{$x+$y} variable name containing expressions
$foo_{$bar}_buh_{$blar} variable name with multiple segments
{$foo_{$x}} will output the variable $foo_1 if $x has a value of 1.
Object method chaining is implemented.
Example: {$object->method1($x)->method2($y)}
{for} tag added for looping (replacement for {section} tag):
{for $x=0, $y=count($foo); $x<$y; $x++} .... {/for}
Any number of statements can be used separated by comma as the first
inital expression at {for}.
{for $x = $start to $end step $step} ... {/for}is in the SVN now .
You can use also
{for $x = $start to $end} ... {/for}
In this case the step value will be automaticall 1 or -1 depending on the start and end values.
Instead of $start and $end you can use any valid expression.
Inside the loop the following special vars can be accessed:
$x@iteration = number of iteration
$x@total = total number of iterations
$x@first = true on first iteration
$x@last = true on last iteration
The Smarty 2 {section} syntax is still supported.
New shorter {foreach} syntax to loop over an array.
Example: {foreach $myarray as $var}...{/foreach}
Within the foreach loop, properties are access via:
$var@key foreach $var array key
$var@iteration foreach current iteration count (1,2,3...)
$var@index foreach current index count (0,1,2...)
$var@total foreach $var array total
$var@first true on first iteration
$var@last true on last iteration
The Smarty 2 {foreach} tag syntax is still supported.
NOTE: {$bar[foo]} still indicates a variable inside of a {section} named foo.
If you want to access an array element with index foo, you must use quotes
such as {$bar['foo']}, or use the dot syntax {$bar.foo}.
while block tag is now implemented:
{while $foo}...{/while}
{while $x lt 10}...{/while}
Direct access to PHP functions:
Just as you can use PHP functions as modifiers directly, you can now access
PHP functions directly, provided they are permitted by security settings:
{time()}
There is a new {function}...{/function} block tag to implement a template function.
This enables reuse of code sequences like a plugin function. It can call itself recursively.
Template function must be called with the new {call name=foo...} tag.
Example:
Template file:
{function name=menu level=0}
<ul class="level{$level}">
{foreach $data as $entry}
{if is_array($entry)}
<li>{$entry@key}</li>
{call name=menu data=$entry level=$level+1}
{else}
<li>{$entry}</li>
{/if}
{/foreach}
</ul>
{/function}
{$menu = ['item1','item2','item3' => ['item3-1','item3-2','item3-3' =>
['item3-3-1','item3-3-2']],'item4']}
{call name=menu data=$menu}
Generated output:
* item1
* item2
* item3
o item3-1
o item3-2
o item3-3
+ item3-3-1
+ item3-3-2
* item4
The function tag itself must have the "name" attribute. This name is the tag
name when calling the function. The function tag may have any number of
additional attributes. These will be default settings for local variables.
New {nocache} block function:
{nocache}...{/nocache} will declare a section of the template to be non-cached
when template caching is enabled.
New nocache attribute:
You can declare variable/function output as non-cached with the nocache attribute.
Examples:
{$foo nocache=true}
{$foo nocache} /* same */
{foo bar="baz" nocache=true}
{foo bar="baz" nocache} /* same */
{time() nocache=true}
{time() nocache} /* same */
Or you can also assign the variable in your script as nocache:
$smarty->assign('foo',$something,true); // third param is nocache setting
{$foo} /* non-cached */
$smarty.current_dir returns the directory name of the current template.
You can use strings directly as templates with the "string" resource type.
Examples:
$smarty->display('string:This is my template, {$foo}!'); // php
{include file="string:This is my template, {$foo}!"} // template
VARIABLE SCOPE / VARIABLE STORAGE
=================================
In Smarty 2, all assigned variables were stored within the Smarty object.
Therefore, all variables assigned in PHP were accessible by all subsequent
fetch and display template calls.
In Smarty 3, we have the choice to assign variables to the main Smarty object,
to user-created data objects, and to user-created template objects.
These objects can be chained. The object at the end of a chain can access all
variables belonging to that template and all variables within the parent objects.
The Smarty object can only be the root of a chain, but a chain can be isolated
from the Smarty object.
All known Smarty assignment interfaces will work on the data and template objects.
Besides the above mentioned objects, there is also a special storage area for
global variables.
A Smarty data object can be created as follows:
$data = $smarty->createData(); // create root data object
$data->assign('foo','bar'); // assign variables as usual
$data->config_load('my.conf'); // load config file
$data= $smarty->createData($smarty); // create data object having a parent link to
the Smarty object
$data2= $smarty->createData($data); // create data object having a parent link to
the $data data object
A template object can be created by using the createTemplate method. It has the
same parameter assignments as the fetch() or display() method.
Function definition:
function createTemplate($template, $cache_id = null, $compile_id = null, $parent = null)
The first parameter can be a template name, a smarty object or a data object.
Examples:
$tpl = $smarty->createTemplate('mytpl.tpl'); // create template object not linked to any parent
$tpl->assign('foo','bar'); // directly assign variables
$tpl->config_load('my.conf'); // load config file
$tpl = $smarty->createTemplate('mytpl.tpl',$smarty); // create template having a parent link to the Smarty object
$tpl = $smarty->createTemplate('mytpl.tpl',$data); // create template having a parent link to the $data object
The standard fetch() and display() methods will implicitly create a template object.
If the $parent parameter is not specified in these method calls, the template object
is will link back to the Smarty object as it's parent.
If a template is called by an {include...} tag from another template, the
subtemplate links back to the calling template as it's parent.
All variables assigned locally or from a parent template are accessible. If the
template creates or modifies a variable by using the {assign var=foo...} or
{$foo=...} tags, these new values are only known locally (local scope). When the
template exits, none of the new variables or modifications can be seen in the
parent template(s). This is same behavior as in Smarty 2.
With Smarty 3, we can assign variables with a scope attribute which allows the
availablility of these new variables or modifications globally (ie in the parent
templates.)
Possible scopes are local, parent, root and global.
Examples:
{assign var=foo value='bar'} // no scope is specified, the default 'local'
{$foo='bar'} // same, local scope
{assign var=foo value='bar' scope='local'} // same, local scope
{assign var=foo value='bar' scope='parent'} // Values will be available to the parent object
{$foo='bar' scope='parent'} // (normally the calling template)
{assign var=foo value='bar' scope='root'} // Values will be exported up to the root object, so they can
{$foo='bar' scope='root'} // be seen from all templates using the same root.
{assign var=foo value='bar' scope='global'} // Values will be exported to global variable storage,
{$foo='bar' scope='global'} // they are available to any and all templates.
The scope attribute can also be attached to the {include...} tag. In this case,
the specified scope will be the default scope for all assignments within the
included template.
PLUGINS
=======
Smarty3 are following the same coding rules as in Smarty2.
The only difference is that the template object is passed as additional third parameter.
smarty_plugintype_name (array $params, object $smarty, object $template)
The Smarty 2 plugins are still compatible as long as they do not make use of specific Smarty2 internals.
TEMPLATE INHERITANCE:
=====================
With template inheritance you can define blocks, which are areas that can be
overriden by child templates, so your templates could look like this:
parent.tpl:
<html>
<head>
<title>{block name='title'}My site name{/block}</title>
</head>
<body>
<h1>{block name='page-title'}Default page title{/block}</h1>
<div id="content">
{block name='content'}
Default content
{/block}
</div>
</body>
</html>
child.tpl:
{extends file='parent.tpl'}
{block name='title'}
Child title
{/block}
grandchild.tpl:
{extends file='child.tpl'}
{block name='title'}Home - {$smarty.block.parent}{/block}
{block name='page-title'}My home{/block}
{block name='content'}
{foreach $images as $img}
<img src="{$img.url}" alt="{$img.description}" />
{/foreach}
{/block}
We redefined all the blocks here, however in the title block we used {$smarty.block.parent},
which tells Smarty to insert the default content from the parent template in its place.
The content block was overriden to display the image files, and page-title has also be
overriden to display a completely different title.
If we render grandchild.tpl we will get this:
<html>
<head>
<title>Home - Child title</title>
</head>
<body>
<h1>My home</h1>
<div id="content">
<img src="/example.jpg" alt="image" />
<img src="/example2.jpg" alt="image" />
<img src="/example3.jpg" alt="image" />
</div>
</body>
</html>
NOTE: In the child templates everything outside the {extends} or {block} tag sections
is ignored.
The inheritance tree can be as big as you want (meaning you can extend a file that
extends another one that extends another one and so on..), but be aware that all files
have to be checked for modifications at runtime so the more inheritance the more overhead you add.
Instead of defining the parent/child relationships with the {extends} tag in the child template you
can use the resource as follow:
$smarty->display('extends:parent.tpl|child.tpl|grandchild.tpl');
Child {block} tags may optionally have a append or prepend attribute. In this case the parent block content
is appended or prepended to the child block content.
{block name='title' append} My title {/block}
PHP STREAMS:
============
(see online documentation)
VARIBLE FILTERS:
================
(see online documentation)
STATIC CLASS ACCESS AND NAMESPACE SUPPORT
=========================================
You can register a class with optional namespace for the use in the template like:
$smarty->register->templateClass('foo','name\name2\myclass');
In the template you can use it like this:
{foo::method()} etc.

= Known incompatibilities with Smarty 2 =
== Syntax ==
Smarty 3 API has a new syntax. Much of the Smarty 2 syntax is supported
by a wrapper but deprecated. See the README that comes with Smarty 3 for more
information.
The {$array|@mod} syntax has always been a bit confusing, where an "@" is required
to apply a modifier to an array instead of the individual elements. Normally you
always want the modifier to apply to the variable regardless of its type. In Smarty 3,
{$array|mod} and {$array|@mod} behave identical. It is safe to drop the "@" and the
modifier will still apply to the array. If you really want the modifier to apply to
each array element, you must loop the array in-template, or use a custom modifier that
supports array iteration. Most smarty functions already escape values where necessary
such as {html_options}
== PHP Version ==
Smarty 3 is PHP 5 only. It will not work with PHP 4.
== {php} Tag ==
The {php} tag is disabled by default. The use of {php} tags is
deprecated. It can be enabled with $smarty->allow_php_tag=true.
But if you scatter PHP code which belongs together into several
{php} tags it may not work any longer.
== Delimiters and whitespace ==
Delimiters surrounded by whitespace are no longer treated as Smarty tags.
Therefore, { foo } will not compile as a tag, you must use {foo}. This change
Makes Javascript/CSS easier to work with, eliminating the need for {literal}.
This can be disabled by setting $smarty->auto_literal = false;
== Unquoted Strings ==
Smarty 2 was a bit more forgiving (and ambiguous) when it comes to unquoted strings
in parameters. Smarty3 is more restrictive. You can still pass strings without quotes
so long as they contain no special characters. (anything outside of A-Za-z0-9_)
For example filename strings must be quoted
<source lang="smarty">
{include file='path/foo.tpl'}
</source>
== Extending the Smarty class ==
Smarty 3 makes use of the __construct method for initialization. If you are extending
the Smarty class, its constructor is not called implicitly if the your child class defines
its own constructor. In order to run Smarty's constructor, a call to parent::__construct()
within your child constructor is required.
<source lang="php">
class MySmarty extends Smarty {
function __construct() {
parent::__construct();
// your initialization code goes here
}
}
</source>
== Autoloader ==
Smarty 3 does register its own autoloader with spl_autoload_register. If your code has
an existing __autoload function then this function must be explicitly registered on
the __autoload stack. See http://us3.php.net/manual/en/function.spl-autoload-register.php
for further details.
== Plugin Filenames ==
Smarty 3 optionally supports the PHP spl_autoloader. The autoloader requires filenames
to be lower case. Because of this, Smarty plugin file names must also be lowercase.
In Smarty 2, mixed case file names did work.
== Scope of Special Smarty Variables ==
In Smarty 2 the special Smarty variables $smarty.section... and $smarty.foreach...
had global scope. If you had loops with the same name in subtemplates you could accidentally
overwrite values of parent template.
In Smarty 3 these special Smarty variable have only local scope in the template which
is defining the loop. If you need their value in a subtemplate you have to pass them
as parameter.
<source lang="smarty">
{include file='path/foo.tpl' index=$smarty.section.foo.index}
</source>
== SMARTY_RESOURCE_CHAR_SET ==
Smarty 3 sets the constant SMARTY_RESOURCE_CHAR_SET to utf-8 as default template charset.
This is now used also on modifiers like escape as default charset. If your templates use
other charsets make sure that you define the constant accordingly. Otherwise you may not
get any output.
== newline at {if} tags ==
A \n was added to the compiled code of the {if},{else},{elseif},{/if} tags to get output of newlines as expected by the template source.
If one of the {if} tags is at the line end you will now get a newline in the HTML output.
== trigger_error() ==
The API function trigger_error() has been removed because it did just map to PHP trigger_error.
However it's still included in the Smarty2 API wrapper.
== Smarty constants ==
The constants
SMARTY_PHP_PASSTHRU
SMARTY_PHP_QUOTE
SMARTY_PHP_REMOVE
SMARTY_PHP_ALLOW
have been replaced with class constants
Smarty::PHP_PASSTHRU
Smarty::PHP_QUOTE
Smarty::PHP_REMOVE

Smarty 3.1 Notes
================
Smarty 3.1 is a departure from 2.0 compatibility. Most notably, all
backward compatibility has been moved to a separate class file named
SmartyBC.class.php. If you require compatibility with 2.0, you will
need to use this class.
Some differences from 3.0 are also present. 3.1 begins the journey of
requiring setters/getters for property access. So far this is only
implemented on the five directory properties: template_dir,
plugins_dir, configs_dir, compile_dir and cache_dir. These properties
are now protected, it is required to use the setters/getters instead.
That said, direct property access will still work, however slightly
slower since they will now fall through __set() and __get() and in
turn passed through the setter/getter methods. 3.2 will exhibit a full
list of setter/getter methods for all (currently) public properties,
so code-completion in your IDE will work as expected.
There is absolutely no PHP allowed in templates any more. All
deprecated features of Smarty 2.0 are gone. Again, use the SmartyBC
class if you need any backward compatibility.
Internal Changes
Full UTF-8 Compatibility
The plugins shipped with Smarty 3.1 have been rewritten to fully
support UTF-8 strings if Multibyte String is available. Without
MBString UTF-8 cannot be handled properly. For those rare cases where
templates themselves have to juggle encodings, the new modifiers
to_charset and from_charset may come in handy.
Plugin API and Performance
All Plugins (modifiers, functions, blocks, resources,
default_template_handlers, etc) are now receiving the
Smarty_Internal_Template instance, where they were supplied with the
Smarty instance in Smarty 3.0. *. As The Smarty_Internal_Template
mimics the behavior of Smarty, this API simplification should not
require any changes to custom plugins.
The plugins shipped with Smarty 3.1 have been rewritten for better
performance. Most notably {html_select_date} and {html_select_time}
have been improved vastly. Performance aside, plugins have also been
reviewed and generalized in their API. {html_select_date} and
{html_select_time} now share almost all available options.
The escape modifier now knows the $double_encode option, which will
prevent entities from being encoded again.
The capitalize modifier now know the $lc_rest option, which makes sure
all letters following a captial letter are lower-cased.
The count_sentences modifier now accepts (.?!) as
legitimate endings of a sentence - previously only (.) was
accepted
The new unescape modifier is there to reverse the effects of the
escape modifier. This applies to the escape formats html, htmlall and
entity.
default_template_handler_func
The invocation of $smarty->$default_template_handler_func had to be
altered. Instead of a Smarty_Internal_Template, the fifth argument is
now provided with the Smarty instance. New footprint:
/**
* Default Template Handler
*
* called when Smarty's file: resource is unable to load a requested file
*
* @param string $type resource type (e.g. "file", "string", "eval", "resource")
* @param string $name resource name (e.g. "foo/bar.tpl")
* @param string &$content template's content
* @param integer &$modified template's modification time
* @param Smarty $smarty Smarty instance
* @return string|boolean path to file or boolean true if $content and $modified
* have been filled, boolean false if no default template
* could be loaded
*/
function default_template_handler_func($type, $name, &$content, &$modified, Smarty $smarty) {
if (false) {
// return corrected filepath
return "/tmp/some/foobar.tpl";
} elseif (false) {
// return a template directly
$content = "the template source";
$modified = time();
return true;
} else {
// tell smarty that we failed
return false;
}
}
Stuff done to the compiler
Many performance improvements have happened internally. One notable
improvement is that all compiled templates are now handled as PHP
functions. This speeds up repeated templates tremendously, as each one
calls an (in-memory) PHP function instead of performing another file
include/scan.
New Features
Template syntax
{block}..{/block}
The {block} tag has a new hide option flag. It does suppress the block
content if no corresponding child block exists.
EXAMPLE:
parent.tpl
{block name=body hide} child content "{$smarty.block.child}" was
inserted {block}
In the above example the whole block will be suppressed if no child
block "body" is existing.
{setfilter}..{/setfilter}
The new {setfilter} block tag allows the definition of filters which
run on variable output.
SYNTAX:
{setfilter filter1|filter2|filter3....}
Smarty3 will lookup up matching filters in the following search order:
1. varibale filter plugin in plugins_dir.
2. a valid modifier. A modifier specification will also accept
additional parameter like filter2:'foo'
3. a PHP function
{/setfilter} will turn previous filter setting off again.
{setfilter} tags can be nested.
EXAMPLE:
{setfilter filter1}
{$foo}
{setfilter filter2}
{$bar}
{/setfilter}
{$buh}
{/setfilter}
{$blar}
In the above example filter1 will run on the output of $foo, filter2
on $bar, filter1 again on $buh and no filter on $blar.
NOTES:
- {$foo nofilter} will suppress the filters
- These filters will run in addition to filters defined by
registerFilter('variable',...), autoLoadFilter('variable',...) and
defined default modifier.
- {setfilter} will effect only the current template, not included
subtemplates.
Resource API
Smarty 3.1 features a new approach to resource management. The
Smarty_Resource API allows simple, yet powerful integration of custom
resources for templates and configuration files. It offers simple
functions for loading data from a custom resource (e.g. database) as
well as define new template types adhering to the special
non-compiling (e,g, plain php) and non-compile-caching (e.g. eval:
resource type) resources.
See demo/plugins/resource.mysql.php for an example custom database
resource.
Note that old-fashioned registration of callbacks for resource
management has been deprecated but is still possible with SmartyBC.
CacheResource API
In line with the Resource API, the CacheResource API offers a more
comfortable handling of output-cache data. With the
Smarty_CacheResource_Custom accessing databases is made simple. With
the introduction of Smarty_CacheResource_KeyValueStore the
implementation of resources like memcache or APC became a no-brainer;
simple hash-based storage systems are now supporting hierarchical
output-caches.
See demo/plugins/cacheresource.mysql.php for an example custom
database CacheResource.
See demo/plugins/cacheresource.memcache.php for an example custom
memcache CacheResource using the KeyValueStore helper.
Note that old-fashioned registration of $cache_handler is not possible
anymore. As the functionality had not been ported to Smarty 3.0.x
properly, it has been dropped from 3.1 completely.
Locking facilities have been implemented to avoid concurrent cache
generation. Enable cache locking by setting
$smarty->cache_locking = true;
Relative Paths in Templates (File-Resource)
As of Smarty 3.1 {include file="../foo.tpl"} and {include
file="./foo.tpl"} will resolve relative to the template they're in.
Relative paths are available with {include file="..."} and
{extends file="..."}. As $smarty->fetch('../foo.tpl') and
$smarty->fetch('./foo.tpl') cannot be relative to a template, an
exception is thrown.
Adressing a specific $template_dir
Smarty 3.1 introduces the $template_dir index notation.
$smarty->fetch('[foo]bar.tpl') and {include file="[foo]bar.tpl"}
require the template bar.tpl to be loaded from $template_dir['foo'];
Smarty::setTemplateDir() and Smarty::addTemplateDir() offer ways to
define indexes along with the actual directories.
Mixing Resources in extends-Resource
Taking the php extends: template resource one step further, it is now
possible to mix resources within an extends: call like
$smarty->fetch("extends:file:foo.tpl|db:bar.tpl");
To make eval: and string: resources available to the inheritance
chain, eval:base64:TPL_STRING and eval:urlencode:TPL_STRING have been
introduced. Supplying the base64 or urlencode flags will trigger
decoding the TPL_STRING in with either base64_decode() or urldecode().
extends-Resource in template inheritance
Template based inheritance may now inherit from php's extends:
resource like {extends file="extends:foo.tpl|db:bar.tpl"}.
New Smarty property escape_html
$smarty->escape_html = true will autoescape all template variable
output by calling htmlspecialchars({$output}, ENT_QUOTES,
SMARTY_RESOURCE_CHAR_SET).
NOTE:
This is a compile time option. If you change the setting you must make
sure that the templates get recompiled.
New option at Smarty property compile_check
The automatic recompilation of modified templates can now be
controlled by the following settings:
$smarty->compile_check = COMPILECHECK_OFF (false) - template files
will not be checked
$smarty->compile_check = COMPILECHECK_ON (true) - template files will
always be checked
$smarty->compile_check = COMPILECHECK_CACHEMISS - template files will
be checked if caching is enabled and there is no existing cache file
or it has expired
Automatic recompilation on Smarty version change
Templates will now be automatically recompiled on Smarty version
changes to avoide incompatibillities in the compiled code. Compiled
template checked against the current setting of the SMARTY_VERSION
constant.
default_config_handler_func()
Analogous to the default_template_handler_func()
default_config_handler_func() has been introduced.
default_plugin_handler_func()
An optional default_plugin_handler_func() can be defined which gets called
by the compiler on tags which can't be resolved internally or by plugins.
The default_plugin_handler() can map tags to plugins on the fly.
New getters/setters
The following setters/getters will be part of the official
documentation, and will be strongly recommended. Direct property
access will still work for the foreseeable future... it will be
transparently routed through the setters/getters, and consequently a
bit slower.
array|string getTemplateDir( [string $index] )
replaces $smarty->template_dir; and $smarty->template_dir[$index];
Smarty setTemplateDir( array|string $path )
replaces $smarty->template_dir = "foo"; and $smarty->template_dir =
array("foo", "bar");
Smarty addTemplateDir( array|string $path, [string $index])
replaces $smarty->template_dir[] = "bar"; and
$smarty->template_dir[$index] = "bar";
array|string getConfigDir( [string $index] )
replaces $smarty->config_dir; and $smarty->config_dir[$index];
Smarty setConfigDir( array|string $path )
replaces $smarty->config_dir = "foo"; and $smarty->config_dir =
array("foo", "bar");
Smarty addConfigDir( array|string $path, [string $index])
replaces $smarty->config_dir[] = "bar"; and
$smarty->config_dir[$index] = "bar";
array getPluginsDir()
replaces $smarty->plugins_dir;
Smarty setPluginsDir( array|string $path )
replaces $smarty->plugins_dir = "foo";
Smarty addPluginsDir( array|string $path )
replaces $smarty->plugins_dir[] = "bar";
string getCompileDir()
replaces $smarty->compile_dir;
Smarty setCompileDir( string $path )
replaces $smarty->compile_dir = "foo";
string getCacheDir()
replaces $smarty->cache_dir;
Smarty setCacheDir( string $path )
replaces $smarty->cache_dir;
