I have implemented a page counter that stores page hits in its own table and records the page ID.

I have written a function that returns the top 5 pages based on views but I only have the page ID's to work with.

How can I get the link to a page based on the page id?

How about using dataobject's get_by_id to return each page then pull the link from that.

I have managed to get the data object using

$dataO = DataObject::get("Page", "`ID` = '$id'");

However I can still not access the link, I though it might be $dataO.Link or $dataO->$Link ?

Link is a method of SiteTree
$dataO->$Link()

Using that gives an undefined variable error. I can see how the functions are inherited but I must still be missing something.

I just tried this and get the same undefined variable error.
$dataO = DataObject::get_by_id("Page", $id);
return $dataO->Link();

but this does work and I'd expect them to both work.
$dataO = DataObject::get_by_id("Page", $id);
return $dataO->AbsoluteLink();
I'd probably stick with
$dataO = DataObject::get_by_id("Page", $id);
return $dataO->RelativeLink();
which also works.

Still having issues with this :/ Thanks for the help so far.

If I var dump $dataO I get the object but if I vardump $dataO->AbsoluteLink() I receive a Server Error Page.I receive the same error with ->RelativeLink()

This is the vardump from $dataO

How about posting the code that $dataO is part of, show some class :).
