writing a plugin, how to disable the comment form altogether?
You can control whether comments appear by filtering the comments_open() function. Here is an example from the WordPress codex: add_filter( ‘comments_open’, ‘my_comments_open’, 10, 2 ); function my_comments_open( $open, $post_id ) { $post = get_post( $post_id ); if ( ‘page’ == $post->post_type ) $open = false; return $open; }
