Question

I don’t need all the menu items and need some custom menu items to be added in the left menu of admin area of WordPress. Is there any function I can use to do this particularly.

Answer 1

Place this code in your themes function.php file and customize as you need

/* Remove unnecessary menu items from admin */
function remove_menus () 
{
    global $menu;

    //$restricted = array(
    //  __('Dashboard'), 
    //  __('Posts'), 
    //  __('Media'), 
    //  __('Links'), 
    //  __('Pages'), 
    //  __('Appearance'), 
    //  __('Tools'), 
    //  __('Users'), 
    //  __('Settings'), 
    //  __('Comments'), 
    //  __('Plugins'));

    $restricted = array(__('Links'),__('Media'),__('Appearance'),__('Tools'),__('Posts'));
    end ($menu);
    while (prev($menu)) {
        $value = explode(' ',$menu[key($menu)][0]);
        if(in_array($value[0] != NULL ? $value[0] : "" , $restricted)){unset($menu[key($menu)]);}
    }

    remove_submenu_page('edit.php','edit.php');
    remove_submenu_page('edit.php','post-new.php');
    remove_submenu_page('index.php','update-core.php');
}
add_action('admin_menu', 'remove_menus');
