json_encode with page_list

Permalink
I have an ajax call that need to receive an array of pages.
What I have until now:
On Submit in PHP
$path = ($_POST['path']);
     $page = Page::getByPath($path);
     $id = $page->getCollectionID();
     Loader::model('page_list');
   $pl = new PageList();
   $pl->filterByParentID($id);
   $results = $pl->getPage();
   echo json_encode($results);


in JS 
success : function(data) {
  alert(data.cID);
}


But I receive undefined.

I guess it is because $results it is an object but not an array.
Any suggestions on how to receive pages and get pagename,url.

Yes, it's an object, not an array.. You have to loop through all the page objects and create an array.
$pages = $pl->getPage();
$ret = array();
foreach ($pages as $page) {
   $ret[] = array('cID'=>$page->getCollectionID(), 'name'=>$page->getCollectionName());
}

and then return $ret...

From your code, but still I receive undefined.
Do I need to loop in JS??

Unless you're happy with just one page you need to loop through the result

There are existing addons for ajaxed page lists and my own Blocks By Ajax addon can be used with page list templates.
