/** | |
* Inspired from: https://gist.github.com/dazecoop/548b2621e86fb030da8e5adb1bfe484f | |
* | |
* How to use: | |
* - add to your function.php or related | |
* | |
* What you can use it for: | |
* Variable products: | |
* - you have variable product with some attributes not used for variations | |
* - you still want to let your users choose some of those attributes values on frontend | |
* - eg: your have an attribute that don't impact prices, and that is required or not, and don't want to create useless variations for those attributes | |
* | |
* Simple product: | |
* - you have a single product, and want to allow user to select some of its attributes values from frontend | |
