Plugin Submenu Admin

Question

How do you create Submenu items for a plugin.

I've checked System Module, That have Submenu class, and Filter on Admin. Is this possible without hacking or Overriding class.

Thanks.

Sure you can.

Layout response object has method 'setLayoutVariable'. One of accepted variables is 'submenu'. If you supply an array of Ip\Menu\Item objects, a submenu will be generated. Here is an example. Put it in Plugin\Application\Event.php file:

<?php

namespace Plugin\Application;


class Event
{
    public static function ipBeforeController()
    {

        if (true) { //find out some kind of a condition when you want a submenu. (eg. ipRequest()->getControllerClass() == 'Plugin\XXX\AdminController')
            $submenu = array();
            $submenuItem = new \Ip\Menu\Item();
            $submenuItem->setTitle('Test');
            $submenuItem->setUrl('http://www.example.com');
            $submenu[] = $submenuItem;

            if (is_object(ipResponse()) && method_exists(ipResponse(), 'setLayoutVariable')) {
                ipResponse()->setLayoutVariable('submenu', $submenu);
            }

        }
    }

}

You can filter main menu too using filter. Add following code to Plugin\Application\Filter.php file:

<?php

namespace Plugin\Application;


class Filter {
    /**
     * @param \Ip\Menu\Item[] $menu
     * @param $info
     */
    public static function ipAdminMenu ($menu, $info)
    {
        //modify $menu

        return $menu;
    }
}
