title: Wordpress custom field info in nav menu?
body: <p>I'm trying to get custom field info from a page into the nav menu. I've had problems with this before... I just don't "get" the walker menu and how it works.</p>
  
  <p>Basically, In addition to the title of the page, I want to have it output the URL of an image and image description from the custom fields and create a menu item linked to a normal WP page.</p>
  
  <p>In the nav-menu-template.php file, I've tried modifying the start_el function by adding get_post_custom_keys() like this with no success:</p>
  
  <pre><code>$item_output .= '&lt;a'. $attributes .'&gt;';
  $item_output .= get_post_custom_values("product_image", $item-&gt;ID);
  $item_output .= $args-&gt;link_before . apply_filters( 'the_title', $item-&gt;title, $item-&gt;ID ) . $args-&gt;link_after;
  </code></pre>
  
  <p>I've also tried get_post_meta(); and others with limited success. The best I've been able to do is either get one of the images repeating in all the links by specifying a a hard integer value. Or, I've been able to get it to output the correct post/page value in text but without an image.</p>
  
  <p>Anyone know of a solution.. what I'm doing wrong?</p>
