免去手動刪除文章中的無用圖片的煩惱，刪除文章后，還需要在回收站中清除才可生效。

在主題的functions.php文件中的<?php 下添加以下代碼：

function delete_post_and_attachments($post_ID) {  
        global $wpdb;  
        //刪除特色圖片  
        $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 );  
        }  
        //刪除圖片附件  
        $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');
