This article will recommend a good shopping cart effect. The main requirements here include a few things. One is written in php for the shopping cart class, and the other is jquery for Ajax operations, there is also a jquery plug-in thickbox. Let's take a look.

Shopping cart type: shop_cart.php
Shopping Cart operation: cart_action.php
Home: index.html
Jquery is used for Ajax operations, and a jquery plug-in thickbox

Let's not talk about it anymore. You can first look at the effect example.
Shop_cart.php is of course the core of the shopping cart, but this class is very simple, because he introduced cart_action.php for external operations. So this class seems quite streamlined.
Shopping Cart class shop_cart.php

The Code is as follows: Copy code

Cart_name = $ name;
$ This-> items =$ _ SESSION [$ this-> cart_name];
}

/**
* SetItemQuantity ()-Set the quantity of an item.
*
* @ Param string $ order_code The order code of the item.
* @ Param int $ quantity The quantity.
*/
Function setItemQuantity ($ order_code, $ quantity ){
$ This-> items [$ order_code] = $ quantity;
}

/**
* GetItemPrice ()-Get the price of an item.
*
* @ Param string $ order_code The order code of the item.
* @ Return int The price.
*/
Function getItemPrice ($ order_code ){
// This is where the code taht retrieves prices
// Goes. We'll just say everything costs $9.99 for this tutorial.
Return 9.99;
}

/**
* GetItemName ()-Get the name of an item.
*
* @ Param string $ order_code The order code of the item.
*/
Function getItemName ($ order_code ){
// This is where the code that retrieves product names
// Goes. We'll just return something generic for this tutorial.
Return 'my Product ('. $ order_code .')';
}

/**
* GetItems ()-Get all items.
*
* @ Return array The items.
*/
Function getItems (){
Return $ this-> items;
}

/**
* HasItems ()-Checks to see if there are items in the cart.
*
* @ Return bool True if there are items.
*/
Function hasItems (){
Return (bool) $ this-> items;
}

/**
* GetItemQuantity ()-Get the quantity of an item in the cart.
*
* @ Param string $ order_code The order code.
* @ Return int The quantity.
*/
Function getItemQuantity ($ order_code ){
Return (int) $ this-> items [$ order_code];
}

/**
* Clean ()-Cleanup the cart contents. If any items have
* Quantity less than one, remove them.
*/
Function clean (){
Foreach ($ this-> items as $ order_code => $ quantity ){
If ($ quantity <1) unset ($ this-> items [$ order_code]);
}
}

/**
* Save ()-Saves the cart to a session variable.
*/
Function save (){
$ This-> clean ();
$ _ SESSION [$ this-> cart_name] = $ this-> items;
}
}

?>

For cart_action, it implements the intermediate role of the shop_cart class and index for updating, deleting, and adding commodity operations.
Cart_action.php

The Code is as follows: Copy code

GetItemQuantity ($ _ GET ['order _ Code']) + $ _ GET ['quantity '];
$ Cart-> setItemQuantity ($ _ GET ['order _ Code'], $ quantity );
} Else {

If (! Empty ($ _ GET ['quantity ']) {
Foreach ($ _ GET ['quantity '] as $ order_code => $ quantity ){
$ Cart-> setItemQuantity ($ order_code, $ quantity );
}
}

If (! Empty ($ _ GET ['delete']) {
Foreach ($ _ GET ['delete'] as $ order_code ){
$ Cart-> setItemQuantity ($ order_code, 0 );
}
}
}
$ Cart-> save ();

Header ('location: cart. php ');

?>

You can also perform external operations by using javasindex.html, that is, adding operations.

The Code is as follows: Copy code
