從wordpress媒體庫中刪除重複的圖像

Question

我想知道如何從wordpress媒體庫中刪除重複的圖像，我也想問媒體上傳器如何檢查文件的重複。

Answer 1

Get all posts. See get_posts(array ('numberposts' => -1)) 
For each post get all attachments. See get_children(array ('post_type' => 'attachment', 'numberposts' => -1)) 
For each attachment get the attachment URL. See wp_get_attachment_url() 
If you find the attachment URL in the parent post's content ($post->post_content): 
    If there is another attachment URL with the same file name plus the 1 and 
    both are part of the post content then 
    remove the second image first then 
    use wp_delete_attachment() to delete the physical file. This will remove all meta data and all associations in other posts too. It is the best way to remove attached files (imho). 

Answer 2

清理未用的圖像和其它文件從上傳的文件夾。

刪除不使用的圖像

http://wordpress.org/plugins/dnui-delete-not-used-image-wordpress/screenshots/

當不使用插件：

go media: Sort files by Unattached. 

delete which is not used.
