Hi there,

I have many-many DOM where Logos are related to NewsPages. I would like to get a NewsPages where LogoID is unique (would like to show only one newspage where is the same LogoID). How could I use array_unique with this dataobject set?:

function GetNewsByLogos() {
	  $doSet = DataObject::get(
		$callerClass = "NewsPage",
		$filter = "`SiteTree`.ParentID = 111 AND `NewsPage`.LogoID != '' ",
		$sort = "",
		$join = "",
		$limit = ""
	  return $doSet ? $doSet : false;

Thanks for any help!

function GetNewsByLogos() {
if($set = DataObject::get("NewsPage", "ParentID = 111 AND `NewsPage`.LogoID != '' "))
return $set->removeDuplicates();
return false;

I tried your code, but it's bringing me no entries after "removeDuplicates".

Before "removeDuplicates" I successfully got 3 news entries:

id1 entry1 logoID=1
id2 entry2 logoID=1
id3 entry3 logoID=2

In example above entry2 has the same logo (logoID=1) and needed to be removed from the displaying on the page. Any ideas how to get this?

I appreciate your help.

Best regards
