QTPro BS

Thanks again @raiwa! 
I had the hooks installed properly. Turns out my problem was that my shopping_cart wasn't modularized. 

So I installed the modular shopping cart and things seem to be working a bit better now. The variables MODULE_CONTENT_SC_PRODUCT_LISTING_QTPRO_CART_BUTTON_UPDATE and MODULE_CONTENT_SC_PRODUCT_LISTING_QTPRO_CART_BUTTON_REMOVE needed to be defined in includes/languages/english/module/content/shopping_cart/cm_sc_product_listing_qtpro.php. (They weren't there already for some reason.)

Now, the only problem left is that the modular shopping cart isn't showing the attributes anymore. Just the dashes, no attribute text. I'm using the stock cm_sc_product_listing_qtpro so I doubt that's the problem.

I've had this issue before, and posted about it earlier in this thread. Back then I fixed the issue (though not knowing how or why it worked) by using FOREACH instead of WHILE, but that fix doesn't seem to be working anymore.

What else could be causing empty attributes in the shopping cart?

Any ideas?

Cheers!

I also posted this question on Stackoverflow since it's probably not osCommerce specific (but I could very well be wrong): https://stackoverflow.com/questions/63853909/how-do-i-debug-this-bit-of-php-and-sql-that-queries-for-an-array-lists-it-and-p

Well. Again. Replacing the WHILE with a FOREACH actually did solve the problem. (I still don't understand why though) I swear I tried it like 3 times, since I remembered that had fixed my problem before I guess I had not done so properly.

My apologies for all the posts. Problem solved. Moving on. Thanks!
