Wordpress plugin won't show on some themes

Question

I have made a wordpress plugin following standard wordpress tutorials. This plugin add a file upload to the comment form by using simply this function:

add_action( 'comment_form_logged_in_after', array(&$this, 'add_to_comment_form') );

. But when I activate some themes it won't show on the comment form.

Any Help how to make it show on comment form?

Answer 1

comment_form_logged_in_after action hook was added to WordPress When comment_form() was introduced at version 3.0.

So the themes where your plugin doesn't work are probably outdated themes that don't use comment_form.

Answer 2

I solved by adding these actions to comments.php of the theme:

<?php if ( is_user_logged_in() ) : ?>
//...................theme code
<?php do_action( 'comment_form_logged_in_after', $comment_author, $user_identity );  ?>

and

do_action( 'comment_form_after_fields' ); 

Hope this help someone and also for theme makers
