[wp-hackers] Prevent attaching unattached attachments (nice!) on sending to editor

[Barry Ceelen]

Hi J.D.

When I use filters inside wp_update_post(), besides probably knowing I’m DOING_AJAX and that I’m dealing with an attachment, I lose context insofar as that I cannot know if the update was triggered by sending an attachment to the editor.
Or am I missing something here?
I went with your suggestion of replacing the core handler, works like a charm.

Thanks for your reply!

In that function you have several filters that you could hook into. wp_insert_post_parent or wp_insert_attachment_data seem like good options. You'd just need to check that that Ajax request is being performed and the post being saved is an attachment, and not modify the post array otherwise.
