When creating a custom filter for “frm_validate_field_entry”, what values are returned for $_POST['item_meta'][n] ?
More specifically, if I have an upload file field in the form, does it return the numeric ID of the file? Or does it return the URL to the uploaded file?
I need the ability to stick the URL to the file into a custom post and I haven’t been able to gain access to it from within the filter.
If the value returned is the numeric ID, can I use “wp_get_attachment_url” to get the URL and put it in the post?

Yes, the media ID is passed after the file is uploaded. That WP function will give you the URL when you give it the id.
