Extension Plugins¶

Extension plugins are used both in the front-end and the backend. They should be created as classes deriving from the base class VmExtendedPlugin:

    public function __construct (&$subject, $config=array()) {
        parent::__construct($subject, $config);
        $this->_path = JPATH_PLUGINS.DS.$this->getName();
        JPlugin::loadLanguage('plg_vmextended_'.$this->getName());
    }

Below is the list with events and a description on what moment they are fired.

  Return:
