comment_form() class_submit not working

[erikfrye]

Using the argument class_submit in comment_form() is not appending the classes to the comment form button.

Following the documentation at ​http://codex.wordpress.org/Function_Reference/comment_form, I should be able to add 'class_submit' => 'something'. However, when I dug into comment-template.php, on line 2233 I saw no mention of adding in the classes.

<input name="<?php echo esc_attr( $args['name_submit'] ); ?>" type="submit" id="<?php echo esc_attr( $args['id_submit'] ); ?>" value="<?php echo esc_attr( $args['label_submit'] ); ?>" />

Everything worked fine when I added in

class="<?php echo esc_attr( $args['class_submit'] ); ?>"

The new line 2233 would look like this

<input name="<?php echo esc_attr( $args['name_submit'] ); ?>" type="submit" class="<?php echo esc_attr( $args['class_submit'] ); ?>" id="<?php echo esc_attr( $args['id_submit'] ); ?>" value="<?php echo esc_attr( $args['label_submit'] ); ?>" />

erikfrye - The way the submit button is built has been refactored for 4.2. See #15015 [31699]. It appears that 'class_submit' should be respected. Can you have a look at the latest trunk to see if the problem persists?

The new line 2233 would look like this

<input name="<?php echo esc_attr( $args['name_submit'] ); ?>" type="submit" class="<?php echo esc_attr( $args['class_submit'] ); ?>" id="<?php echo esc_attr( $args['id_submit'] ); ?>" value="<?php echo esc_attr( $args['label_submit'] ); ?>" />

It already looks like this​, see [29809]. Make sure you're on 4.1.x or 4.2-beta.

Your line number indicates that you're on 4.0.x (ref​).

Sorry about that. I have multiple instances running. I upgraded one of them, but not the one I was actually working on.
