Really need help, ecshop shopping cart for advice. Thanks to the Bulls ...
Ecshop to develop a feature, click "Add Cart" to jump to the shopping cart page, on this page, there is a group of numbers, select a number $shoujihao to add to the current shopping cart properties.
Now that the number has been set, to do is to select a number in front of the radio box click Submit to add the number to the shopping cart in the "Properties" box.


Studied the long time and knew the process of adding a shopping cart.
When the user clicks the "Add to Cart" button, the program performs the following procedure:

1, call the function under Js/common.js AddToCart ()

2, the first step is to perform an AJAX request to page Flow.php?step=add_to_cart

3, the second step calls the function Addto_cart () to add the item to the shopping cart.
But specific to how to add or more confused, choose the number of click Submit is the update shopping cart, or re-add shopping cart? Re-add to retrieve the data, then update the shopping cart how to do?
Really anxious, sincere thanks, cattle people ...
