    Hi all,

    Is it possible to customize comment_form() changing the callback?

    I have this function in functions.php:

    function custom_comment_form( $args = array(), $post_id = null ) {
        global $user_identity, $id;
    
        if ( null === $post_id )
            $post_id = $id;
        else
            $id = $post_id;
    
        $commenter = wp_get_current_commenter();
    
        $req = get_option( 'require_name_email' );
        $aria_req = ( $req ? " aria-required='true'" : '' );
        $fields =  array(
            'author' => '<p class="comment-form-author">' . '<label for="author">' . __( 'Name' ) . '</label> ' . ( $req ? '<span class="required">*</span>' : '' ) .
                        '<input id="author" name="author" type="text" value="' . esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' /></p>',
            'email'  => '<p class="comment-form-email"><label for="email">' . __( 'Email' ) . '</label> ' . ( $req ? '<span class="required">*</span>' : '' ) .
                        '<input id="email" name="email" type="text" value="' . esc_attr(  $commenter['comment_author_email'] ) . '" size="30"' . $aria_req . ' /></p>',
            'url'    => '<p class="comment-form-url"><label for="url">' . __( 'Website' ) . '</label>' .
                        '<input id="url" name="url" type="text" value="' . esc_attr( $commenter['comment_author_url'] ) . '" size="30" /></p>',
        );
    
        $required_text = sprintf( ' ' . __('Required fields are marked %s'), '<span class="required">*</span>' );
        $defaults = array(
            'fields'               => apply_filters( 'comment_form_default_fields', $fields ),
            'comment_field'        => '<p class="comment-form-comment"><label for="comment">' . _x( 'Comment', 'noun' ) . '</label><textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea></p>',
            'must_log_in'          => '<p class="must-log-in">' .  sprintf( __( 'You must be <a href="%s">logged in</a> to post a comment.' ), wp_login_url( apply_filters( 'the_permalink', get_permalink( $post_id ) ) ) ) . '</p>',
            'logged_in_as'         => '<p class="logged-in-as">' . sprintf( __( 'Logged in as <a href="%1$s">%2$s</a>. <a href="%3$s" title="Log out of this account">Log out?</a>' ), admin_url( 'profile.php' ), $user_identity, wp_logout_url( apply_filters( 'the_permalink', get_permalink( $post_id ) ) ) ) . '</p>',
            'comment_notes_before' => '<p class="comment-notes">' . __( 'Your email address will not be published.' ) . ( $req ? $required_text : '' ) . '</p>',

            'label_submit'         => __( 'Post Comment' ),

                                <?php do_action( 'comment_form_logged_in_after', $commenter, $user_identity ); ?>
                            <?php else : ?>

                                do_action( 'comment_form_after_fields' );
                                ?>
                            <?php endif; ?>
                            <?php echo apply_filters( 'comment_form_field_comment', $args['comment_field'] ); ?>
                            <?php echo $args['comment_notes_after']; ?>
                            <p class="form-submit">
                                <input name="submit" type="submit" class="btn btn-primary" 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(); ?>
                            </p>
                            <?php do_action( 'comment_form', $post_id ); ?>
                        </form>
                    <?php endif; ?>
                </div><!-- #respond -->
                <?php do_action( 'comment_form_after' ); ?>
            <?php else : ?>
                <?php do_action( 'comment_form_comments_closed' ); ?>
            <?php endif; ?>
        <?php
    }

    I would like to override default template and to use mine.

    <?php comment_form( array( 'callback' => 'custom_comment_form' ) ); ?>

    I tried the code above in comments.php but won't works.
    Do you have some suggestions? Thank you so much, Vi.

    I'm wrong. I just understand that there is not a callback for comment_form().
    How could I, for example, add class to submit button?
