Comment submit button disappeared after 4.2 update

Me, too. Will try your solution – thanks!

Ciao,

Someone from the WordPress dev community, please explain what’s going on with this. I’m having the same issue and not really in the mood to blindly copy core functions from the old version to the new one.

Thanks teszter to tell me solutions.

Same problem here. I thought it was because of all the customizations I had ventured to make in the comment_form() now being misaligned with the new updates. Glad to see I’m not the only one.

I found differences between the comment-template.php files from before and after the WordPress 4.2 version. (posted below) Can anyone tell how we can fix things with the new info?

https://developer.wordpress.org/reference/hooks/comment_form_submit_button/

With a diff tool to compare the comment-template.php files:
All this…

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

…seems to have been substituted by this:

<?php
						$submit_button = sprintf(
							$args['submit_button'],
							esc_attr( $args['name_submit'] ),
							esc_attr( $args['id_submit'] ),
							esc_attr( $args['class_submit'] ),
							esc_attr( $args['label_submit'] )
						);

						/**
						 * Filter the submit button for the comment form to display.
						 *
						 * @since 4.2.0
						 *
						 * @param string $submit_button HTML markup for the submit button.
						 * @param array  $args          Arguments passed to <code>comment_form()</code>.
						 */
						$submit_button = apply_filters( 'comment_form_submit_button', $submit_button, $args );

						$submit_field = sprintf(
							$args['submit_field'],
							$submit_button,
							get_comment_id_fields( $post_id )
						);

						/**
						 * Filter the submit field for the comment form to display.
						 *
						 * The submit field includes the submit button, hidden fields for the
						 * comment form, and any wrapper markup.
						 *
						 * @since 4.2.0
						 *
						 * @param string $submit_field HTML markup for the submit field.
						 * @param array  $args         Arguments passed to comment_form().
						 */
						echo apply_filters( 'comment_form_submit_field', $submit_field, $args );

Here’s one more voice heaping thanks onto martijnn94. We appreciate it!

If its so easy, why doesn’t WP simply implement this little fix? Then it would only be necessary to reinstall 4.2.1. I’m just running a blog on WP, and never imagined I’d have to learn how to debug all the faulty code.
Aren’t updates supposed to improve things, and not create havoc? Anyway, am I supposed to simply copy the new default comments form? And if so where do I insert it?
If WP were a car, I wouldn’t recommend anyone buying it unless he/she were a master mechanic.
