I have to intercept the checkout button of my prestashop 1.7 site with a JS that calls a PHP class which receives as parameters a multidimensional array with product_id and quantity present in the cart and possibly returns an error that blocks the order by issuing a popup message. The PHP class is already written. If you can let me know. Thank you.
