Question

Check if a menu page was already added in wordpress admin

Asked by: Dzynit

I have more than one plugin developed by the same company.

Since all the plugins need to share the same top level menu (a top level of their own, not one of the pre-existing wordpress menus), I need to check for a main page being added and know if this main menu has already been added by one of the several plugins by this company.

See if I can explain more clearly with an example:
I have plugin 1, plugin 2, and plugin 3. This particular user is only using plugin 1 and 3. Plugin 1 will load first - checking and seeing that the main menu is not there, it will add it. When plugin 3 loads, I need it to first check - is that main menu already added? If yes, then just add your submenus to it, if not, add the main menu.

Make sense? I just need to figure out the way to do this "check" that I can use in all the plugins. With one common way to check for the main menu being there - only one of them would add it and all would list their submenus under it.

Thanks for any help on this. I'm sure there is some variable that can be read to make this work, it's just not jumping out at me.

it would be more helpful if you could post the link to those plug-in so we can check and have some suggestions for you

All the plugins are using a hard coded if statement checking for each other right now. It's getting unmanageable as the number of plugins grow.

There must be some way to just check for a top level menu existing.

This is how I was able to make it work. I added this same piece of code to all of the plugin:

	global $menu;
	foreach ($menu as $i) {
		$key = array_search('toplevel_page_my_plugin_hook', $i);
		if ($key != '') {
			$menu_added = true;
		}
	}
	if ($menu_added) {
	} else {
//add main menu
}
//add sub menus
