WordPress 后台很多模块有时并不需要,使用下面的代码可以将它们屏蔽掉。根据需要,将下面代码添加到当前主题functions.php模板文件中:

屏蔽左侧菜单


function remove_menus() {
    global $menu;
    $restricted = array(
        __('Dashboard'),
        __('Posts'),
        __('Media'),
        __('Links'),
        __('Pages'),
        __('Appearance'),
        __('Tools'),
        __('Users'),
        __('Settings'),
        __('Comments'),
        __('Plugins')
    );
    end ($menu);
    while (prev($menu)){
        $value = explode(' ',$menu[key($menu)][0]);
        if(strpos($value[0], '<') === FALSE) {
            if(in_array($value[0] != NULL ? $value[0]:"" , $restricted)){
                unset($menu[key($menu)]);
            }
        }else {
        $value2 = explode('<', $value[0]);
            if(in_array($value2[0] != NULL ? $value2[0]:"" , $restricted)){
                unset($menu[key($menu)]);
            }
        }
    }
}
if (is_admin()){
    // 屏蔽左侧菜单
    add_action('admin_menu', 'remove_menus');
}

删除子菜单


function remove_submenu() {
    // 删除”设置”下面的子菜单”隐私”
    remove_submenu_page('options-general.php', 'options-privacy.php');
    // 删除”外观”下面的子菜单”编辑”
    remove_submenu_page('themes.php', 'theme-editor.php');
}
if (is_admin()){
    //删除子菜单
    add_action('admin_init','remove_submenu');
}

屏蔽后台更新模块


function wp_hide_nag() {
    remove_action( 'admin_notices', 'update_nag', 3 );
}
add_action('admin_menu','wp_hide_nag');

屏蔽 WP 后台“显示选项”和“帮助”选项卡


function remove_screen_options(){ return false;}
    add_filter('screen_options_show_screen', 'remove_screen_options');
    add_filter( 'contextual_help', 'wpse50723_remove_help', 999, 3 );
    function wpse50723_remove_help($old_help, $screen_id, $screen){
    $screen->remove_help_tabs();
    return $old_help;
}
