Load Multiple Arguments to a View with PHP Code
Okay...Here's the right way to do it. I was running into a problem with empty key values. I had to create the array out of the user reference fields I wanted, scrape any of the empty array keys  

$node = node_load(arg(1));

if($node ) {
$user_args = array(
$node-&gt;uid,
$node-&gt;field_am_reference[0]['uid'],
$node-&gt;field_realtor_reference[0]['uid'],
$node-&gt;field_title_rep_reference[0]['uid']

);
//Remove empty array values and thier respective keys 
  $clean_args = array_filter($user_args, 'strlen'); 

//Take all of the array values and put them into a single key 
  $safe_args = implode(',' , $clean_args);

return $safe_args;
}



else  {

return FALSE;

}
