This is the code here, it is grabbing records from the pageview table that records page views. Its returning the id fine, now I just need to get the url and page name so I can use them in the view.

Sorry I should have started with this...

public function MostViewed($limit = 5) {
		//Returns a list of page id's
		$ID = PageView::get()

			->sort('Count', 'DESC');


        /*loop through each of the records retrieved and grab the link by matching the page id to the
        * corresponding data object.
        */
        foreach ($ID as $id){

            //get the page id from the retrieved record
           $PageId = $id->PageID;
            
            $DataObject = DataObject::get("Page", "`ID` = '$PageId'");


        }

        //should be returning the page url here or object to retrieve the url from
        return $ID;

	}

This code makes no sense, have you have trimmed out a heap of lines?
There is nowhere that you have built the data to be returned, you are returning $ID, the foreach loop is doing nothing.
Maybe you need to be using a join between your page and PageVew to get what you're after rather than a for loop.
Either that or the for loop needs to build an array to return.
