Frequently Bought Together causes fatal error if inserted into Elementor Popup

Hey, I suspect this is just a regular ol’ Elementor bug.

Seems like the FBT integration uses the global $product to fetch products, but this fails when editing a popup containing this element because… well, it’s a popup, not a product.

Recreating the issue is quite simple:

1) Create an Elementor Popup
2) Insert the Frequently Bought Together element
3) Save the popup.
4) Try to access the popup editor again after navigating away.

Here is the error log:

Hello,

Could you please record a short video so we can better understand how to reproduce the issue?

Thank you in advance.

Sure thing, see private information section here.

This element works only on the single product page. It can’t be placed to a custom page.

Ah okay, fair enough.

Is there a different way to include the element in a popup?

Unfortunately, this element is not designed to work inside the popup.

I see – thank you for checking.

Is there a way to modify the FBT element to include a HTML block?

We can use a functions.php hook or something if that’s the easiest way to do it.

Hello,

You can try to do this by yourself but we don’t have instructions for such customizations. Find the code for this module here inc/integrations/woocommerce/modules/frequently-bought-together

Kind Regards

Hey,

Thanks – we’ll give it a shot. Can we override this file in our child theme? Just so we don’t have to change it every time the theme updates 😉

You can override only core WordPress template files like header.php, footer.php, index.php and others. Unfortunately, these files can’t be overridden.
