Hello, I'm having a problem and I'd like to ask for help from you. It is as follows:
I'm integrating a PHP system into the Wordpress Woocommerce plugin and I need to order some products from the database, so far so good. The problem starts when fetching the product from the table. She is like this
Order id meta_key value
1 2 3
2 2 87
3 3 45
I need to select id 1 that contains value 3 as long as id 2 contains the value 87. How do I do this? I'm completely lost.
