I invested a good deal of time today customizing a comment form in a BuddyPress child theme. My goals were to:
- Add a new field called, “Organization”
- Remove the “URL” field
- Remove the “Comment” text that appears above the corresponding textarea
The biggest learning for me was figuring out how comment_form, comments_template, and wp_list_comments fit together.
I learned a lot from Otto’s article on the subject, but that article didn’t address everything I needed to accomplish. The following is what I did to accomplish the aforementioned goals.
In functions.php, I have the following:
// Change "Website" to "Organization" on the comment form. add_filter('comment_form_default_fields','add_organization_to_comments'); function add_organization_to_comments($fields) { // New fields $fields['organization'] = '<p><label>Organization</label><input type="text" name="organization" value="'.(!empty($_POST['organization']) ? esc_attr( $_POST['organization']) : '').'" /></p>'; $fields['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>'; $fields['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"' . $aria_req . ' /></p>'; // Remove unwanted default fields unset($fields['url']); return $fields; } // save extra fields in database add_action( 'comment_post', 'save_comment' ); function save_comment($comment_id) { add_comment_meta( $comment_id, 'organization', esc_attr($_POST['organization']), true ); } |
That’s it!
Tomorrow I will share how I displayed the “organization” field in the “comments” panel of the WordPress admin screen.

This code leaves your site open to a XSS attack through the comments form. I highly recommend filtering the POSTed organization field.
@Otto – Thanks for the heads-up there!
All, I have incorporated Otto’s suggestion and added the esc_attr() function to the POSTs in the code above.
