ClassicPress Plugin Development: Rename First Sublevel Menu of a Custom Top Level Menu

This post is part of the ClassicPress Plugin Development series in which I am going to look at both best practice for developing plugins and how I approach some requirements as well as some of the functions I commonly use.

In the last post I showed how to create a custom top level menu and mentioned it creted both the top level menu and a sublevel menu of the same name.

As the below example, extracted from my To Twitter plugin which adds a submenu to the existing azrcrv-tt menu with a name of Settings. As the first, $parent_slug, and fifth, $menu_slug parameters match the top level menu the add_submenu_page function renames the default first submenu entry:

add_action('admin_menu', 'azrcrv_tt_create_admin_menu');

/**
 * Add to menu.
 *
 * @since 1.0.0
 *
 */
function azrcrv_tt_create_admin_menu(){
    
	add_submenu_page(
				'azrcrv-tt'
				,__('Settings', 'to-twitter')
				,__('Settings', 'to-twitter')
				,'manage_options'
				,'azrcrv-tt'
				,'azrcrv_t_display_options');
				
}

To rename a custom top level menu on a network admin dashboard, change the admin_menu tag in the add_action function call to network_admin_menu.
