wordpress让每个用户只能看自己上传的图片

代码：

/**
* WordPress 媒体库只显示用户自己上传的文件
* https://www.wpdaxue.com/view-user-own-media-only.html
*/
//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 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','my_upload_media');

//在[媒体库]只显示用户上传的文件
function 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', 'my_media_library' );
