If I want to globally change the comment form for a theme I would use
add_filter for “comment_form_default_fields”. Then I might use
add_action for “comment_form_logged_in_after” and “comment_form_after_fields”. What I want to do, however, is create a single page with customised comment form fields.
My first thought was to add filters and use hooks in a custom page template. But that will, at best, work for one or two sites. What I am hoping to find is another way that I can target a chosen page. Is there a hook, filter, or logical test I can apply to modify a single page?
