wordpress后台的模块很多,但并不是每个都经常用到。介绍几段代码,可以根据自己的需要屏蔽不常用的模块,借此提升wordpress后台运行效率。

将下面的代码根据需要复制到wordpress主题的模版文件functions.php中:

一、屏蔽左侧菜单

  1. function remove_menus() {
  2.     global $menu;
  3.     $restricted = array(
  4.         __('Dashboard'),
  5.         __('Posts'),
  6.         __('Media'),
  7.         __('Links'),
  8.         __('Pages'),
  9.         __('Appearance'),
  10.         __('Tools'),
  11.         __('Users'),
  12.         __('Settings'),
  13.         __('Comments'),
  14.         __('Plugins')
  15.     );
  16.     end ($menu);
  17.     while (prev($menu)){
  18.         $value = explode(' ',$menu[key($menu)][0]);
  19.         if(strpos($value[0], '<') === FALSE) {
  20.             if(in_array($value[0] != NULL ? $value[0]:"" , $restricted)){
  21.                 unset($menu[key($menu)]);
  22.             }
  23.         }else {
  24.         $value2 = explode('<', $value[0]);
  25.             if(in_array($value2[0] != NULL ? $value2[0]:"" , $restricted)){
  26.                 unset($menu[key($menu)]);
  27.             }
  28.         }
  29.     }
  30. }
  31. if (is_admin()){
  32.     // 屏蔽左侧菜单
  33.     add_action('admin_menu', 'remove_menus');
  34. }

二、删除子菜单

  1. function remove_submenu() {
  2.     // 删除”设置”下面的子菜单”隐私”
  3.     remove_submenu_page('options-general.php', 'options-privacy.php');
  4.     // 删除”外观”下面的子菜单”编辑”
  5.     remove_submenu_page('themes.php', 'theme-editor.php');
  6. }
  7. if (is_admin()){
  8.     //删除子菜单
  9.     add_action('admin_init','remove_submenu');
  10. }

三、屏蔽后台更新模块

  1. function wp_hide_nag() {
  2.     remove_action( 'admin_notices', 'update_nag', 3 );
  3. }
  4. add_action('admin_menu','wp_hide_nag');

四、屏蔽后台“显示选项”和“帮助”选项卡

  1. function remove_screen_options(){ return false;}
  2.     add_filter('screen_options_show_screen', 'remove_screen_options');
  3.     add_filter( 'contextual_help', 'wpse50723_remove_help', 999, 3 );
  4.     function wpse50723_remove_help($old_help, $screen_id, $screen){
  5.     $screen->remove_help_tabs();
  6.     return $old_help;
  7. }

五、屏蔽仪表盘中的无用模块

  1. function example_remove_dashboard_widgets() {
  2.     // Globalize the metaboxes array, this holds all the widgets for wp-admin
  3.     global $wp_meta_boxes;
  4.     // 以下这一行代码将删除 "快速发布" 模块
  5.     unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_quick_press']);
  6.     // 以下这一行代码将删除 "引入链接" 模块
  7.     unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_incoming_links']);
  8.     // 以下这一行代码将删除 "插件" 模块
  9.     unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_plugins']);
  10.     // 以下这一行代码将删除 "近期评论" 模块
  11.     unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_comments']);
  12.     // 以下这一行代码将删除 "近期草稿" 模块
  13.     unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_recent_drafts']);
  14.     // 以下这一行代码将删除 "WordPress 开发日志" 模块
  15.     unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_primary']);
  16.     // 以下这一行代码将删除 "其它 WordPress 新闻" 模块
  17.     unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_secondary']);
  18.     // 以下这一行代码将删除 "概况" 模块
  19.     unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_right_now']);
  20. }
  21. add_action('wp_dashboard_setup', 'example_remove_dashboard_widgets' );

六、屏蔽后台页脚版本信息

  1. function change_footer_admin () {return '';}
  2. add_filter('admin_footer_text', 'change_footer_admin', 9999);
  3. function change_footer_version() {return '';}
  4. add_filter( 'update_footer', 'change_footer_version', 9999);

七、屏蔽后台左上LOGO

  1. function annointed_admin_bar_remove() {
  2.         global $wp_admin_bar;
  3.         /* Remove their stuff */
  4.         $wp_admin_bar->remove_menu('wp-logo');
  5. }
  6. add_action('wp_before_admin_bar_render', 'annointed_admin_bar_remove', 0);

以上介绍的wordpress技巧,仅是将这些模块暂时隐藏起来,而并非删除。今后需要的时候,只需将相对应的代码从functions.php文件中移除,即可恢复被屏蔽的模块。
