WordPress 媒体库只显示用户自己上传的文件

有时候我们给用户后台发布的权限，可是不想让用户看到所有的媒体库，可以使用View Own Posts Media Only插件，也可以在当前主题的 functions.php 文件添加下面的代码：

//在文章编辑页面的[添加媒体]只显示用户自己上传的文件  function MBT_my_upload_media( $wp_query_obj ) {   global $current_user, $pagenow;   if( !is_a( $current_user, 'WP_User') )   return;   if( 'admin-ajax.php' != $pagenow || $_REQUEST['action'] != 'query-attachments' )   return;   if( !current_user_can( 'manage_options' ) &amp;&amp; !current_user_can('manage_media_library') )   $wp_query_obj-&gt;set('author', $current_user-&gt;ID );   return;  }  add_action('pre_get_posts','MBT_my_upload_media');  //在[媒体库]只显示用户上传的文件  function MBT_my_media_library( $wp_query ) {   if ( strpos( $_SERVER[ 'REQUEST_URI' ], '/wp-admin/upload.php' ) !== false ) {   if ( !current_user_can( 'manage_options' ) &amp;&amp; !current_user_can( 'manage_media_library' ) ) {   global $current_user;   $wp_query-&gt;set( 'author', $current_user-&gt;id );   }   }  }  add_filter('parse_query', 'MBT_my_media_library' );

//在文章编辑页面的[添加媒体]只显示用户自己上传的文件 function MBT_my_upload_media( $wp_query_obj ) { global $current_user, $pagenow; if( !is_a( $current_user, 'WP_User') ) return; if( 'admin-ajax.php' != $pagenow || $_REQUEST['action'] != 'query-attachments' ) return; if( !current_user_can( 'manage_options' ) && !current_user_can('manage_media_library') ) $wp_query_obj->set('author', $current_user->ID ); return; } add_action('pre_get_posts','MBT_my_upload_media'); //在[媒体库]只显示用户上传的文件 function MBT_my_media_library( $wp_query ) { if ( strpos( $_SERVER[ 'REQUEST_URI' ], '/wp-admin/upload.php' ) !== false ) { if ( !current_user_can( 'manage_options' ) && !current_user_can( 'manage_media_library' ) ) { global $current_user; $wp_query->set( 'author', $current_user->id ); } } } add_filter('parse_query', 'MBT_my_media_library' );
