Is there a method in the PageList object or somewhere else in concrete5 to get multiple pages back using an array of PageIDs/ciDs? Something like:
Page::getByIDs( array(23,343,44,334,6) );
So I figured it out. I think this is the first time I answered my own question. Yay me!
Loader::model('page_list');
$pl = new PageList();
$pl->filter('p1.cID', array(1,2,65,69,70), '=');
return $pl->get();
The p1.cID is part of the SQL query Concrete is generating. Its the alias and column name for page.cid. The array is just the array of pageIDs you want to find. "=" is the operator (not IN which is what I thought it would be.)
It helps to read the documentation:
