Looking for the filter hook for the admin/comments/reply to process (where you use 'reply to' in the comments administration screen). This will be used in a custom plugin.
(The plugin adds a hidden field to a front-end entered comment to reduce bot-entered comments. The extra field is inserted properly on the front end, but not in the admin comment list page.)
I need to
- add a hidden field to the comment drop-down on the comments admin list (the comment field that shows when you click the 'reply' link for a comment).
- add some pre-processing to the comment drop-down when it is submitted and before WP processes the comment.
Not sure where to start on this, although I think it is in https://developer.wordpress.org/reference/files/wp-admin/includes/class-wp-comments-list-table.php/ .
Am I on the right track? Is there a filter for the adding of fields to the comment box form that is on the admin/comments page?
(Note: had posted this question in StackExchange main area by mistake. And got a down-vote and close vote without explanation for my efforts. So duplicating the question here - where I meant to put it.)
Added
The hidden field is added to the comment form on the front end with the 'add_meta_boxes_comment' action hook, which uses the 'add_meta_box' function to specify the field and the callback function for that inserted/hidden field.
The hidden/added field is processed via the 'edit_comment' hook. If the hidden field is not there, then the comment is not saved.
This works fine in the front-end, but the hidden/added field is not added to the comment form in the back-end's "Reply" on the comment list page.
