af/form/editing/query_param
Filter for the URL query parameter used to identify the post a form should edit, when the form’s post argument is set to param. Defaults to post (so ?post=123 selects post 123 for editing). Change it if post clashes with another query parameter on your site.
add_filter( 'af/form/editing/query_param', function ( $query_param, $form, $args ) { return 'edit_post_id';}, 10, 3 );With the filter above, the form would look for the post ID in ?edit_post_id=123 instead.
The filter receives the current $query_param (defaults to 'post'), the $form array, and the $args array. Return the desired parameter name as a string.
