Alter render (array) of a field in a View?
I'd take a look at the views_pre_render(&amp;$view); hook.  There, in your module, you can do stuff like:

 function MYMODULE_views_pre_render(&amp;$view) {

   if ($view-&gt;name=='viewyouarelookingfor') {

      // do whatever you want

   }

 }


and do whatever you want meaning you have access to $view->result which is an array of all the raw data making up each row.  Throw in  a drupal_set_message('&lt;pre&gt;' . print_r($view-&gt;result, true) . '&lt;/pre&gt;'); or its equivalent to take a peek at that and you should be able to work all kinds of magic.

If this doesn't work to your needs, you can still render the field any way you like from a view template for that row or field itself.
