首先利用宝塔或则FTP打开/inc/options下的admin-options.php文件把下面代码放在20行左右
- array(
- ‘id’ => ‘is_delete_article’,
- ‘type’ => ‘switcher’,
- ‘title’ => ‘删除文章同时删除图片’,
- ‘label’ => ‘启用后在删除文章时会删除文章对应的图片’,
- ‘default’ => false,
- ),
最后在主题根目录下打开functions.php将以下代码放在最后即可
- //+———————————————————————-
- //| 删除文章时删除图片附件
- //+———————————————————————-
- function delete_post_and_attachments($post_ID) {
- global $wpdb;
- //删除特色图片
- $thumbnails = $wpdb->get_results( “SELECT * FROM $wpdb->postmeta WHERE meta_key = ‘_thumbnail_id’ AND post_id = $post_ID” );
- foreach ( $thumbnails as $thumbnail ) {
- wp_delete_attachment( $thumbnail->meta_value, true );
- }
- //删除图片附件
- $attachments = $wpdb->get_results( “SELECT * FROM $wpdb->posts WHERE post_parent = $post_ID AND post_type = ‘attachment'” );
- foreach ( $attachments as $attachment ) {
- wp_delete_attachment( $attachment->ID, true );
- }
- $wpdb->query( “DELETE FROM $wpdb->postmeta WHERE meta_key = ‘_thumbnail_id’ AND post_id = $post_ID” );
- }
- if(_cao(‘is_delete_article’) ){
- add_action(‘before_delete_post’, ‘delete_post_and_attachments’);
