WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I've got the following code, which cleans up a lot of stuff that is not going to be used within the admin area:

add_action( 'admin_menu', 'my_remove_menu_pages' );

function my_remove_menu_pages() {
  remove_menu_page( 'edit.php' );                   //Posts
  remove_menu_page( 'upload.php' );                 //Media
  remove_menu_page( 'edit-comments.php' );          //Comments
  remove_menu_page( 'themes.php' );                 //Appearance
  remove_menu_page( 'users.php' );                  //Users
  remove_menu_page( 'tools.php' );                  //Tools
  remove_menu_page( 'options-general.php' );        //Settings

};

However, there are two menu items that have been inserted from plugins.

When I hover over each menu item, it says the links are:

/wp-admin/edit.php?post_type=acf
/wp-admin/admin.php?page=wpcf7

Is there a way to hide these menu pages, too?

May be Stupid to ask, but why hack the admin menu, when you could deactivate the plugins in question? –  eyoung100 May 23 at 21:27
    
@eyoung100 There are several reasons. The most apparent one would be to hide certain functionality from specific user( role)s. Also one might want to restructure the admin menu, and thus need to remove (and add back again) certain menu entries. –  t f Oct 23 at 17:16

You need to use the right hooks (which are not always the same as the URL/slug), and it doesn't hurt do use a hook that runs later (e.g., admin_init):

add_action('admin_init', 'wpse_136058_remove_menu_pages');
function wpse_136058_remove_menu_pages() {
    remove_menu_page('edit.php?post_type=acf');
    remove_menu_page('wpcf7');
} // function wpse_136058_remove_menu_pages

You can use the following to debug:

add_action('admin_init', 'wpse_136058_debug_admin_menu');
function wpse_136058_debug_admin_menu() {
    echo '<pre>'.print_r($GLOBALS['menu'], true).'</pre>';
} // function wpse_136058_debug_admin_menu

This gives (for my setup) the following for the Contact Form 7 plugin menu page:

[27] => Array
        (
            [0] => Formular
            [1] => wpcf7_read_contact_forms
            [2] => wpcf7
            [3] => Contact Form 7
            [4] => menu-top menu-icon-generic toplevel_page_wpcf7 menu-top-last
            [5] => toplevel_page_wpcf7
            [6] => none
        )

And the array element with key 2 is what you are looking for: wpcf7

You probably need to set the add_action priority to a higher number and target those two new links specifically like so:

add_action( 'admin_menu', 'my_remove_menu_pages', 999 );

function my_remove_menu_pages() {
  remove_menu_page( 'edit.php' );                   //Posts
  remove_menu_page( 'upload.php' );                 //Media
  remove_menu_page( 'edit-comments.php' );          //Comments
  remove_menu_page( 'themes.php' );                 //Appearance
  remove_menu_page( 'users.php' );                  //Users
  remove_menu_page( 'tools.php' );                  //Tools
  remove_menu_page( 'options-general.php' );        //Settings
  remove_menu_page( 'edit.php?post_type=acf' );
  remove_menu_page( 'wpcf7' );
};

Advanced Custom Fields also provides a help document on how to do this for their menu here:

http://www.advancedcustomfields.com/resources/how-to/how-to-hide-acf-menu-from-clients/

Contact Form 7 also has it's own way of restricting the visibility of the menu:

Instead of specifying the menus you want to remove, specify the menues you want to keep :)

add_action('admin_init', 'nwcm_admin_init');

function nwcm_admin_init()
{   
    // Remove unnecessary menus 
    $menus_to_stay = array(
        // Client manager
        'nwcm',

        // Dashboard
        'index.php',

        // Users
        'users.php'
    );      
    foreach ($GLOBALS['menu'] as $key => $value) {          
        if (!in_array($value[2], $menus_to_stay)) remove_menu_page($value[2]);
    }   

} 

This way you don't have to search for plugin names and modify the code when you add new plugins..

I like your way! –  Nicholas Decker Oct 29 at 13:43
    // PLUGINS THAT ADD AS DASHBOARD SUBMENU
    // IF THIS IS THE URL BELOW - THE PAGE VARIABLE IS WHAT I NEED ( SO WHATEVER COMES AFTER PAGE= )
    // http://example.com/wp-admin/index.php?page=iconize-plugin-update-notifier
    remove_submenu_page( 'index.php', 'iconize-plugin-update-notifier' );

    // OR FOR EXAMPLE WOOCOMMERCE DASHBOARD SUBMENU
    remove_submenu_page( 'index.php', 'wc-about' ); //WOO
    remove_submenu_page( 'index.php', 'wc-credits' ); //WOO
    remove_submenu_page( 'index.php', 'wc-translators' ); //WOO

    // CUSTOM POST TYPE TOP LEVELS
    remove_menu_page( 'edit.php?post_type={$POST_TYPE}' ); //LOOK FOR WHAT COMES AFTER POST TYPE IN THE URL
    remove_menu_page( 'edit.php?post_type=testimonials-widget' ); //TESTIMONIALS WIDGET
    remove_menu_page( 'edit.php?post_type=product' ); //WOOCOMMERCE

    // CUSTOM POST TYPE SUBMENU
     remove_submenu_page( 'edit.php?post_type={$POST_TYPE}', '{$SUBMENU_URL_VARIABLE}' ); //EXAMPLE FORMAT
     // SO IF BELOW IS THE URL
     // http://example.com/wp-admin/edit.php?post_type=testimonials-widget&page=testimonialswidget_settings
     // YOU NEED TO SEE WHATS AFTER PAGE
     remove_submenu_page( 'edit.php?post_type=testimonials-widget', 'testimonialswidget_settings' ); //TESTIMONIALS WIDGET

    // OTHER EXAMPLES
    remove_menu_page( 'revslider' ); // REVSLIDER
    remove_menu_page( 'woocommerce' ); // WOOCOMMERCE
    remove_menu_page( 'order-post-types-shop_order' ); // WOOCOMMERCE
    remove_menu_page( 'order-post-types-shop_coupons' ); // WOOCOMMERCE
    remove_menu_page( 'shortcodes-ultimate' ); // SHORTCODES ULTIMATE
    remove_menu_page( 'wp-admin-microblog/wp-admin-microblog.php' ); // ADMIN MICROBLOG
    remove_menu_page( 'snippets' ); //CODE SNIPPETS
    remove_menu_page( 'gf_edit_forms' ); // GRAVITY FORMS
        remove_submenu_page( 'gf_edit_forms', 'gf_settings' ); // GRAVITY FORMS
        remove_submenu_page( 'gf_edit_forms', 'gf_export' ); // GRAVITY FORMS
        remove_submenu_page( 'gf_edit_forms', 'gf_update' ); // GRAVITY FORMS
        remove_submenu_page( 'gf_edit_forms', 'gf_addons' ); // GRAVITY FORMS
        remove_submenu_page( 'gf_edit_forms', 'gf_help' ); // GRAVITY FORMS

        remove_submenu_page( 'cleverness-to-do-list', 'cleverness-to-do-list-settings' ); //Cleverness TODO

YOU CAN DEBUG ALL THIS WITH THE FOLLOWING TO GET ALL THE INFO YOU NEED:

if (!function_exists('debug_admin_menus')):
function debug_admin_menus() {
if ( !is_admin())
        return;
    global $submenu, $menu, $pagenow;
    if ( current_user_can('manage_options') ) { // ONLY DO THIS FOR ADMIN
        if( $pagenow == 'index.php' ) {  // PRINTS ON DASHBOARD
            echo '<pre>'; print_r( $menu ); echo '</pre>'; // TOP LEVEL MENUS
            echo '<pre>'; print_r( $submenu ); echo '</pre>'; // SUBMENUS
        }
    }
}
add_action( 'admin_notices', 'debug_admin_menus' );
endif;

The keys will give you the array values that allow you do all of this with wordpress globals (although not recommended)

function remove_submenus_all_please() {
if ( !is_admin())
        return;
  global $submenu;
    unset($submenu['index.php'][10]); // Removes Updates
  //Posts menu
 // unset($submenu['edit.php'][5]); // Leads to listing of available posts to edit
 // unset($submenu['edit.php'][10]); // Add new post
 // unset($submenu['edit.php'][15]); // Remove categories
 // unset($submenu['edit.php'][16]); // Removes Post Tags
}
add_action('admin_menu', 'remove_submenus_all_please', 999);

And to remove for certain users just do the same thing except with capabilities added:

function remove_by_caps_admin_menu() {
if ( !is_admin())
        return;
    if ( !current_user_can('manage_options') ) {
        remove_menu_page( 'revslider' ); // REVSLIDER
    } elseif ( !current_user_can('edit_posts') ) {
        remove_menu_page( 'woocommerce' ); // WOO
    } else {
    }
}
add_action('admin_menu', 'remove_by_caps_admin_menu', 999);

AND TO TIE IT ALL TOGETHER WHY NOT SHORTEN OUR CODE? YOU CAN USE ARRAYS TO AVOID WRITING remove_submenu_page 50 times. This also works with the toolbar nodes:

if ( !function_exists( 'remove_admin_menupages_in_array' ) ) {
function remove_admin_menupages_in_array() {
    if ( !is_admin())
        return;
          $admin_menus = array(
                                'revslider',
                                'woocommerce',
                                'shortcodes-ultimate',
          );

    foreach ( $admin_menus as $menu_page ) {
        if ( !current_user_can('manage_options') ) {
            remove_menu_page( $menu_page );
        }
    } // foreach
 } // function
add_action('admin_menu', 'remove_admin_menupages_in_array', 9999);
} // exists
