programmatically create woocommerce product in php

programmatically_create_variable.php

//Hi, i created a function for adding variable products based on your code. I share it here in case anyone needs it:

//The first parameter is the title of the product, $cats is the products category id which has to be an array and must be created previously, $variations is an array which contains the variations with prices, descriptions, discount, and $variations_key is the key of the parent attribute which has to be created previously on teh attributes page.

//I´m creating a ticket´s selling store and I´m using 2 globals: $logger and $vgh from my framework, please ignore them.

Happy that you shared this piece of code, although it would be nice of you to explain how all variables look. You reference several variables that are not documented 😊 @the-neardy-dot-info
