‘delete_attachment’ works for me. How are you deleting attachments? ‘delete_attachment’ fires from wp_delete_attachment(), which is called from wp-admin/post.php?action=delete, which is the link followed when one picks “delete permanently” from the media library.
The action passes the attachment ID to your callback, that seems to be all anyone would need.
Hi,
Yes I am using wp-admin/post.php?action=delete through the media library menu.
This is the code I’m using to hook into the action:
add_action('delete_attachment', array ($this, 'media_overwrite_perserve_attachments'));
I just found out that if I have a syntax errors in my media_overwrite_perserve_attachments($post_id) function it redirect’s to a blank page. So I guess that the hook is indeed working, it’s my code that’s the problem 😛
Thanks for pointing me to the correct hook.
Hi.
So, i think we need to view a code from
media_overwrite_perserve_attachments
. Can you show it?
It was just some debugging code to display a JS alert box (it previously had a spelling mistake which caused a syntax error):
MediaOverwriteUtils::displayAlert("deleting file");
Which calls:
class MediaOverwriteUtils {
public static function insertJS($JSContent) {
return "<script language='javascript'>
" . $JSContent . "
</script>";
}
public static function displayAlert($alertContent) {
echo MediaOverwriteUtils::insertJS("alert('" . $alertContent . "');");
}
}
It works when called from action hooks that don’t do a page refresh/redirect such as ‘wp_handle_upload_prefilter’, but ‘delete_attachments’ apparently doesn’t execute it (probably due to page refresh).
I have yet to write any of the actual code for preserving files used by multiple attachments, that’s why marked this issue as resolved.
