ClassicPress Plugin Development: Create Submenu for a Custom Post Type

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.

If you’ve created a plugin with a custom post type you can add additional submenus to the custom post types top level menu. I typically use this to add the options page of the plugin. This is basically done as a variation on the theme of adding a submenu to custom top level menu.

This is an example from my From Twitter plugin which has a custom post type called Tweet; the key difference between this and adding a submenu to the Settings menu is the $tag which is the first argument.

/**
 * Add to menu.
 *
 * @since 1.0.0
 *
 */
function azrcrv_ft_create_admin_menu(){
	
	add_submenu_page(
						'edit.php?post_type=tweet'
						,esc_html__('From Twitter Settings', 'from-twitter')
						,esc_html__('Settings', 'from-twitter')
						,'manage_options'
						,'azrcrv-ft'
						,'azrcrv_ft_display_options'
					);
	
}

You can find the tag to use by hovering the mouse over the top level menu of the custom post type.
