前言
很多朋友wordpress删除文章时候文章的图片和略缩图源文件并不会从服务器删除,对于强迫症来说这太难受了,去网上搜索了一下,有相关的教程,下面的代码放到主题的functions.php文件中就可以
/* 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" );
}
add_action('before_delete_post', 'delete_post_and_attachments');
/* 删除文章时删除图片附件over */
