Currently You are now a website builder. These are the code in my cart.php & functions.php. Currently, i am very satisfied with my layout. However, I want to achieve cart like Shopee / Taobao / Lazada, that allow my customer to
1) Do selective checkout, where only selected items are sent to checkout page, and after order created, only these items will be removed from cart. On the other side, non-selected items are retained inside cart, until customer remove them manually through 清除購物車 / 移除選中商品 or customer check out them. Only remove when order is created. If customer go back from checkout page or payment page, or anything, as long as order is not created, dont remove them. Currently im using restore cart way to achieve this, but everything from cart is removed currently after order created. theres some mistake that stop me from achieving this. I turned on feature where customer can see how many items are inside cart through the cart icon at header. At the same time, i dont want my customer to notice that their cart is cleared and recovered before (the amount of items in cart icon will show 0 when havent recover and the number of items after recover). I dont want them to notice the change, therefore, we have to recover it fast until customer did not notice them. Please be considerate regarding customer that use PC because they might access my website through another tab, at there, they can see the amount of items in cart icon. Therefore, i want it to always show the correct amount, only remove when the order is created and maintain if the order is not created. I dont want them to notice how it works (recovering)
2) All these
全选
刪除選中的商品
清空購物車
输入优惠券代码
应用优惠券
已选商品: 0 件，共计: RM0.00
结算
works perfectly fine, please remain them.
Maintaining all the layout and achieved functions. Please check which part stopped me from achieving the selective checkout (maintain non-selected items inside cart, only remove selected to checkout items when order created, and dont let customer nmotice the change in their cart. I want them to no matter access from where, either new tab, other device etc, they will see the correct items in their cart)
For now, If i cancel the payment halfway, i am logged out when back from payment page, and when i check from other tab, non-selected items are removed from cart, only selected items are still inside cart. Also, when i login back after payment page, it redirects me to pay-only page. Please refer how taobao cart works, and review which part is stopping me from achieve taobao cart, give me the part of code to be changed and the new code to replaced with the current one.
