Hey Beka!

This code is awesome - thank you for your hard work. My only issue is that I want to allow my client's customers to re-purchase only one product category. In this case it's a category called "gift-cards" (id=470). So far I have tried to just simply isolate a product id to be allowed for repurchase. But even this has its bugs:
if ( $product_id = 43026) {
return $purchasable;
}

Would you be able to help me with the category conditionality?

Hey Beka,

I am new to woo-commerce can you instruct me where to put the above code to run the site perfectly .

I already purchased the woo-commerce membership plugin and installed it. and I restricted a downloadable product to count according to membership and put amount of product is free because i restricted them with membership so user already paid for membership so he can easily get that product as free and after that he can download but download count is 3 (for example) so he download one so the remaining is 2 now but if he can purchase again then the download count start again from 3 , hope you understand my requirement.

That would be great helpful
Thank You

Wordpress in debug mode give me notice "Notice: Trying to get property of non-object" to line if ( wc_customer_bought_product( get_current_user()->user_email, get_current_user_id(), $product_id ) ) { $purchasable = false; }

This is great. Any way to add a time limit? Say limit purchase every 30 days?

Great code but I have a problem with wpml (multilanguage) which is not detecting the purchase in another language, I solved the problem with small adaption:

How should this code be modified to disable a variable product regardless of which variation is selected on the initial purchase?
