Change Comment form text

Hello,

Add the below code to the functions.php file of the child theme. Modify the code as per your need –

function placeholder_comment_form_fields($fields) {
    $replace_author = __('Your Name', 'yourdomain');
    $replace_email = __('Your Email', 'yourdomain');
    $replace_url = __('Your Website', 'yourdomain');
    
    $fields['author'] = '<p class="comment-form-author">' . '<label for="author">' . __( 'Name', 'yourdomain' ) . '</label> ' . ( $req ? '<span class="required">*</span>' : '' ) .
                    '<input id="author" name="author" type="text" placeholder="'.$replace_author.'" value="' . esc_attr( $commenter['comment_author'] ) . '" size="20"' . $aria_req . ' /></p>';
                    
    $fields['email'] = '<p class="comment-form-email"><label for="email">' . __( 'Email', 'yourdomain' ) . '</label> ' .
    ( $req ? '<span class="required">*</span>' : '' ) .
    '<input id="email" name="email" type="text" placeholder="'.$replace_email.'" value="' . esc_attr(  $commenter['comment_author_email'] ) .
    '" size="30"' . $aria_req . ' /></p>';
    
    $fields['url'] = '<p class="comment-form-url"><label for="url">' . __( 'Website', 'yourdomain' ) . '</label>' .
    '<input id="url" name="url" type="text" placeholder="'.$replace_url.'" value="' . esc_attr( $commenter['comment_author_url'] ) .
    '" size="30" /></p>';
    
    return $fields;
}
add_filter('comment_form_default_fields','placeholder_comment_form_fields');

Replace yourdomain with oceanwp and edit the text Your Name, Your Email, Your Website as per your need.
Add this code to the functions.php file of the oceanwp child theme.

Did you clear the cache after adding the code? It should work. Can you link to the site for which you have added the code?

Do you want to translate the placeholder or want to change it? For translation, you can use Loco translate plugin or edit the Pot file under oceanwp > languages folder using a PoEdit tool.
