How to limit related items to a category? was created by Gorast

Hi,
I need to relate Actor to its Performance. I do this by tags. The problem is that other actors that have same performance show in the related items. How can I limit related items to show related items ONLY from category Performances?

Thanks,
Gorast

The query does not distinguish categories. We could have it though as an option in upcoming releases (noted).

In the meantime, your best bet is to simply override the itemlist.php model in the frontend (function getRelatedItems()) and simply extend with your rules.

It's not Joomla in this case, it's a function specific to K2 and it's plain SQL. Nothing fancy.

Try to replace the query line with this one:

$query = "SELECT t.itemID FROM #__k2_tags_xref AS t JOIN #__k2_items AS i ON t.itemID = i.id WHERE t.tagID IN ({$sql}) AND t.itemID != {$itemID}  AND i.catid = (SELECT catid FROM #__k2_items WHERE id = {$itemID}) GROUP BY t.itemID";

If it works with you, I can help to implement this feature in the upcoming release.

No, you will modify itemlist.php model in the frontend as Fotis said

You will replace this line:

$query = "SELECT itemID FROM #__k2_tags_xref WHERE tagID IN ({$sql}) AND itemID!={$itemID} GROUP BY itemID";

It did nothing. Should I manually put the ID of the Category I want the items from?

Tnx,
Gorast

Have you modified the models/itemlist.php file?
The query I detects the category id from the item being viewed.
