title: Rendering only the URL from a Drupal 7 custom field
body: <p>I'm having a hard time rendering just the url (no title, div markup, etc) for a custom field within custom node display of <code>node--My_Content_Type_Node.tpl.php</code>. I have been attempting to go the route outlined <a href="https://stackoverflow.com/questions/8727234/extract-url-from-link-field-in-drupal">here</a>, but have been having a tough time. Here are my specifics:</p>
  
  <p>My custom field is a Taxonomy term reference to forums, with the machine name of <code>taxonomy_forums</code></p>
  
  <p>I have been trying to use the following (along with subtle variations), with no success:</p>
  
  <pre><code>$url = render($node-&gt;taxonomy_forums[$node-&gt;language][0]['url']);
  </code></pre>
  
  <p>Essentially, I am trying to tie content to a specific precreated forum for comment, and create a link to it.</p>
  
  <p>I can display the default layout (link, title, markup) by using the following, but no luck seperating it out:</p>
  
  <pre><code>$Forum = render($content['taxonomy_forums']);
  </code></pre>
  
  <p>Any help greatly appreciated, and this is my first post here, so please let me know if any more details are needed.</p>
  
  <p>Thanks!</p>
  
  <p>Update: Recaiving the following for the var dump:</p>
  
  <p><code>array(1) { ["und"]=> array(1) { [0]=> array(2) { ["tid"]=> string(1) "5" ["taxonomy_term"]=> object(stdClass)#81 (8) { ["tid"]=> string(1) "5" ["vid"]=> string(1) "2" ["name"]=> string(13) "Total Rewards" ["description"]=> string(167) "Use this space to ask questions, make comments, or start a conversation with Grameen Foundation and other site users related to assessing your total rewards practices."
