thanks, but i'm not sure you understood my problem

I have array with ID of pages
(for example 35 43 30 32 40 50 83 52)
and I want to create DataList with DataObjects in same order as in array

(or maybe i dont understand how to use sort method in this case, can you show me it in code please)

Sorry, I misunderstood your problem, but although you can use the sort metod combined with SQL functions .

You have an array with product ids and want to create a DataList with that products wich are in the same order like in your array?

Try the following:

// $idList is a comma separated string?
$dl = DataList::create('ProductPage')->byIDs(array($idList[0]))->sort('FIELD(ID, ' . $idList . ')');

// Plain SQL would look like
// SELECT * FROM ProductPage WHERE ID IN (35, 43 ,30 ,32) ORDER BY FIELD (ID, 35, 43, 30, 32);

If you are planning for this to be in a GridField and you wish to change the sorting I would checkout the Sortable GridField Component.

Then you can drag and drop those items into whatever order you want and just use the sort() function when you build the list.
