Make Search and Archives match homepage

I have my homepage http://www.faberunashop.com set up as a directory. When you click on the post image, it takes you over to the artists site. Here is the code that I used to make this happen by adding it to the functions.php:

function print_post_title() {
    global $post;
    $thePostID = $post->ID;
    $post_id = get_post($thePostID);
    $title = $开发者_JS百科post_id->post_title;
    $perm  = get_permalink($post_id);
    $post_keys = array(); $post_val  = array();
    $post_keys = get_post_custom_keys($thePostID);

    if (!empty($post_keys)) {
      foreach ($post_keys as $pkey) {
            if ($pkey=='url1' || $pkey=='title_url' || $pkey=='url_title') {
              $post_val = get_post_custom_values($pkey);
            }
      }
      if (empty($post_val)) {
            $link = $perm;
      } else {
            $link = $post_val[0];
      }
    } else {
      $link = $perm;
    }
    echo '<h2><a href="'.$link.'" rel="bookmark" title="'.$title.'">'.$title.'</a></h2>';
}

Now I want to do the same to my search and archive page. What do I adjust to make them behave the same?

I suppose that you use WordPress.

In that case you can change the layout and the behavior of your search results by creating a file with name search.php into your theme for your search results, and another file for archives that called archives.php.
