Sorry not get your point. I just need to send new customization fields data on cart with product. Just give me a one solution that how am I put customization fields data in ajax like product_id. I think solution must be like this:
data: {'action': 'add-to-cart', 'add': 1, 'ajax': true, 'qty': 1, 'id_product': id_product, 'token': static_token, 'id_customization': [217]},
But its not working 
Can you hel me how may I arrange it so it sends customization to cart?
