I've added an Entries field called linkedCourseEntry to a Product (Product Type > Product Fields tab). In the Product itself I've assigned an entry.

I need to access linkedCourseEntry from one or more Events, but can’t work out how to do so.

For example when EVENT_POPULATE_LINE_ITEM is used:

    function(LineItemEvent $event) {

        $lineItem = $event->lineItem;
        $purchasable = $lineItem->getPurchasable();

        // Somehow access the 'linkedCourseEntry' data here... help! 

Can anyone point me in the right direction please?


I believe you're looking for something like:

  • Yes. Brilliant. Thank you. I'd love to know 'how' you know that? I've not been able to find this indicated in the docs, and of I take a look at the $purchasable object I don't see 'product' as an item. Cheers though! Jul 24 '20 at 21:29

    I knew this because $purchasable is an instance of a Variant, and all variants have a parent product. If you dump out $purchasable (Craft::dd($purchasable);) you can see that it's a Variant and has a nested object representing the Product. Here's the relevant part of the docs: docs.craftcms.com/commerce/api/v3/… Jul 27 '20 at 8:55
