Remove link from $title in comments

Question

I'm using Drupal 7. When I post a comment to an article, its title looks like <a class="permalink" rel="bookmark" href="/comment/9#comment-9">comment title</a>.

I need only the “comment title” to be displayed, without the link.

I found the code in the comment.tpl.php template where the title of the comment is printing.

  <?php print render($title_prefix); ?>
  <h2<?php print $title_attributes; >><b><?php print $title></b></h2>

  <?php print render($title_suffix); ?>

As is said in the file description, $title already contains the link, so I can’t change it!

$title: Linked title

Does anybody know if there is a way to print the comment's title without a link?

Answer 1

Instead of

<?php print $title; ?>

You can do:

<?php print check_plain($comment->subject); ?>

Answer 2

Easiest way is to paste this code in template.php of your current theme, replace the word THEMENAME with the name of your theme (lowercase of course) and flush your cache:

/**
 * Preprocess theme_comment()
 */
function THEMENAME_preprocess_comment(&$variables) {
  // Remove all HTML tags from the title
  $variables['title'] = strip_tags($variables['title']);
}
