| - | ====== Technical changes in Piwigo 2.7 ====== | ||
| - | ===== add_event_handler() 4th parameter ===== | ||
| - | The fourth parameter of **add_event_handler** function was used to tell the number of parameters which will be transmitted to the callback. This is no longer used: all parameters given to **trigger_change** or **trigger_notify** are always transmitted to all callback. | ||
| - | |||
| - | But the fourth parameter is still used: if a string is given it will be used as a file path included just before the callback (with **include_once**). | ||
| - | <code php> | ||
| - | // procedural | ||
| - | add_event_handler('init', 'my_init', | ||
| - | EVENT_HANDLER_PRIORITY_NEUTRAL, | ||
| - | MY_PLUGIN_PATH . 'include/callbacks.php' | ||
| - | ); | ||
| - | |||
| - | // OOP with static method | ||
| - | add_event_handler('init', array('MyClass', 'init'), | ||
| - | EVENT_HANDLER_PRIORITY_NEUTRAL, | ||
| - | MY_PLUGIN_PATH . 'include/myclass.php' | ||
| - | ); | ||

| - | If the 4th parameter is anything else than a string it is ignored. | ||
