Hi,
you have to write a complex meta_query to get this working. I’ll try to make it clear by explaining it in steps.
First, I’ve rewritten your code a bit to eliminate french words, just so it’s obvious what we’re doing. I’m on the “Work” page here. This is the setup before we get into code:
CUSTOM POST TYPE Products
– Product 1
– Product 2
– Product 3
CUSTOM POST TYPE Recipes
– Recipe 1 (has Product 2 an Product 3 linked)
– Recipe 2 (has Product 2 linked)
– Recipe 3 (has Product 1 and Product 2 linked)
PAGE Work
– has Product 1 and Product 3 linked
… now you want to display all the Recipes that are shared between the current page (Work) and the Recipe. The correct result will be Recipe 1 and Recipe 3.
The easy first step (you’ve done it already) is to get products for the current page and their ID’s into an array:
// GET PRODUCTS FOR THE CURRENT PAGE (two products)
$products = get_field('products_under_work');
// var_dump($products); // returns "Product 1" (id=15) and "Product 3" (id=19)
// GET AN ARRAY OF PRODUCT ID'S ONLY
$product_ids = array();
foreach($products as $product) :
array_push($product_ids, $product->ID);
endforeach;
// var_dump($product_ids); // 15,19
(continued in next post)
