Comment Form Submission: need action hook

[tonebari]

I wrote a little AJAX plugin to challenge-response the browser on comment form load. It provides CAPTCHA if no JavaScript. Problem is I had to hack wp-comments-post to use wp_die() if validation doesn't happen. It would be awesome to have an action hook right after nocache_headers().

Punting due to feature freeze. Reconsider with next release.

itching to close as invalid. wp-load.php ends with the init hook. you can use it to conditionally call nocache_headers() and die if your check is failed.

attaching a patch nonetheless.

please close as invalid/wontfix if this doesn't make it into 2.8.

You can already use the pre_process_comment hook in wp_new_comment to achieve what you want.

However, I can see the benefit of another hook here for earlier work.

I am going to add an action to the if/then/else that appears just after so it only fires if WordPress would have accepted the comment anyway.

New action is called 'pre_comment_on_post'

(In [11248]) Add 'pre_comment_on_post' action to allow early denial by spam plugin. Fixes #8343.
