How can I add php code force cart_payment_id:0 while open checkout progress ??")* Hi, The payment method is automatically preselected when the cart is loaded, whether it's on the checkout or another page which displays the cart. Even if you set it to 0, the loading function of the cart will re-set it to the default payment method id. So you would have to modify the "getFullCart" function of the file administrator/components/com_hikashop/classes/cart.php to load set the payment_id when not already set. However, this might lead to some erratic behavior as the new cart and checkout system introduced in HikaShop 3 has been made with the intent of auto selecting the payment method like that in order to avoid many issues that plagued previous versions of the checkout because of that. I would personnally advise not changing that and try to see if you can't do something else for your problematic.

How can I add php code force cart_payment_id:0 while open checkout progress ??")* Hi, I don't see how the default behavior of the system is different from your needs ? By default, when you add a product to the cart and go to the checkout a default payment method will be preselected in the cart_payment_id, however, the customer will still be able to change it if he wants on the checkout and that change will be saved in his cart. If he comes back later on and add another product to the cart and go to the checkout, the previously selected payment method will still be selected and the customer will still be able to choose another one if he wants to. So why would you want to set the cart_payment_id to 0 ? and at which point in the process ? You could use one of the triggers called during the loading of the cart I guess... However, I've never done that so I can't guarantee anything.
