I'm having difficulty figuring out how to get what I want here;
building a form, and admin area of a module, and I want to allow the user to choose a Select dropdown, which was populated by core entityreference, which listed only content of type PAGE.
Anyone know of some example code for that?
I came across this recently for Drupal and this was helpful.
Actually, this was for using the entityreference_autocomplete module.

Eventually, after another cup of coffee, this works:
$query = new EntityFieldQuery();
$query
->entityCondition('entity_type', 'node')
->propertyCondition('type', 'page');
$nodes = $query->execute();
$rn=array(0=>'None');
foreach($nodes['node'] as $ln){
if($nn=node_load($ln->entity_id)){
$rn[$ln->entity_id]=$nn->title; //build an assoc array for use on SELECT field
}
}
return $rn;
Where the returned $rn array is used as the options array for a Form Select element.
