Friendika Addon/Plugin development
|
|
|
|
This is an early specification and hook details may be subject to change.
|
|
|
|
Please see the sample addon 'randplace' for a working example of using these features.
|
|
|
|
|
|
You must register plugins with the system in the .htconfig.php file.
|
|
|
|
$a->config['system']['addon'] = 'plugin1name, plugin2name, another_name';
|
|
|
|
Plugin names cannot contain spaces and are used as filenames.
|
|
|
|
|
|
Register your plugin hooks during installation.
|
|
|
|
register_hook($hookname, $file, $function);
|
|
|
|
$hookname is a string and corresponds to a known Friendika hook
|
|
$file is a pathname relative to the top-level Friendika directory.
|
|
This *should* be 'addon/plugin_name/plugin_name.php' in most cases.
|
|
$function is a string and is the name of the function which will be executed
|
|
when the hook is called.
|
|
|
|
|
|
Your hook functions will be called with at least one and possibly two arguments
|
|
|
|
function myhook_function(&$a, &$b) {
|
|
|
|
|
|
}
|
|
|
|
If you wish to make changes to the calling data, you must declare them as
|
|
reference variables (with '&') during function declaration.
|
|
|
|
$a is the Friendika 'App' class - which contains a wealth of information
|
|
about the current state of Friendika, such as which module has been called,
|
|
configuration info, the page contents at the point the hook was invoked, profile
|
|
and user information, etc. It is recommeded you call this '$a' to match its usage
|
|
elsewhere.
|
|
|
|
$b can be called anything you like. This is information which is specific to the hook
|
|
currently being processed, and generally contains information that is being immediately
|
|
processed or acted on that you can use, display, or alter. Remember to declare it with
|
|
'&' if you wish to alter it.
|
|
|
|
|
