No read more link in content views

I adapted a neat little solution here #287812: Provide a "Content: Read more link" field to make a 'Read full post' link display on nodes that have further body content to view, and re-used the 'subscribe' css class to make the link appear like the 'join' and 'request to join' links in the group directory.

• Download/install Views Custom Field module.
• Add, exclude from view and remove labels for a node path and a node body field
• Add a customfield, remove label.
• Re-order the fields and move below teaser
• Rewrite Path field output to something like<a href="[path]">Read full post&raquo;</a>
• Rewrite customfield output to something like<div class="views-field-subscribe"><span class="[phpcode]"> [path]</span></div>
• Add a php value to the customfield of
  

  <?php
  print (strlen($data->node_revisions_body) > strlen($data->node_revisions_teaser) ? 'readmorelink': 'hidden');
  ?>

• Add to css .hidden { visibility: hidden; }

Looks good to me.
