More info for autocomplete choices? When I have an entity reference field with an autocomplete widget, is there a way to add a field to the info that appears in the autocomplete choices? Seems like the default field is Title, but this in my case might be ambiguous.
An easier solution is to modify the 'label callback' property of the node entity.

function mymodule_entity_info_alter(&amp;$entity_info) {
    $entity_info['node']['label callback'] = '_mymodule_label_callback_set';
}

function _mymodule_label_callback_set($entity, $entity_type){
    if($entity_type == 'node' &amp;&amp; $entity-&gt;type == 'my_node_type'){
        //Compute new label here
       $label = 'test';
       return $label;
    }
}
