Webforce Cart (wfCart) is a free PHP shopping cart class you can use a component of a PHP based online store. Its designed as a component for PHP developers who would rather write their own store rather than a complete solution.
Instructions and examples for the free PHP Shopping Cart
To use the cart in an existing script:
Rename wfcart.php.txt to wfcart.php and upload to your server.
Then include the file:
include("wfcart.php");
Start the session, and assign the cart to it. NOTE: You must include the file wfcart.php before you start the session, its just the way PHP works.
session_start();
$cart =& $_SESSION[cart];
if(!is_object($cart)) $cart = new wfCart();
Then you can use the functions like $cart->get_contents();, these functions are documented below.
Adding an Item - $cart->add_item( code , quantity , price , info )
If you have a widget with code AB313 and a price of $40.11, you can add it to the cart with :
$cart->add_item(AB313,1,40.11,Widget AB313 Standard);
If the item AB313 is alreay in the cart, then the quantity of it will be increased by the quantity supplied to the function, in this case 1. The itemid must be unique, and can be letters and/or numbers.
Deleting an Item - $cart->del_item( itemid );
E.g. to delete the item ID 123
$cart->del_item(123);
Changing the quantity of an item -
$cart->edit_item( itemid, new_quantity );
For example :
$cart->edit_item(HA2,3);
If you set the quanitity to zero, the item is deleted.
Getting the number of items in a cart
echo $cart->itemcount;
Getting the total value of the cart.
echo $cart->total;
Emptying the cart
$cart->empty_cart();
Getting the cart contents
$items = $cart->get_contents();
$items is an array, so the following code displays the items.
foreach($items as $item) {
echo "Code/ID :".$item[id]."
";
echo "Quantity:".$item[qty]."
";
echo "Price :".$item[price]."
";
echo "Info :".$item[info]."
";
echo "Subtotal".$item[subtotal]."
";
}
Note, subtotal is quantity X price for that item, not a running total..
Extending Webforce Cart
There are 2 functions you can create that will enable more flexability.
One is wf_get_price( itemid, qty ). If you need to do pricing based on Quantity ( e.g. bulk discounts ) then you can create a function called wf_get_price to do what you need itto do. If you do not pass a price to add_item, then the wf_ get_price function will be called. If you use this functionality, AND your price is quantity dependant, then you must uncomment the line in the edit_item function.
The other is wf_get_info, again, if you do not pass info to add_item then get_info will be called. TIP: you do not have to pass a string to add_item(), you could use an array of infomation instead. e.g. add_item( AS2112,5,19.95,array(size=>large,color=>red)); then when you use get_contents, you echo $item[info][color] etc.
Enhancements:
- The empty cart function was fixed.

Zen Cart truly is the art of e-commerce; a free, user-friendly, open source shopping cart system. Zen Cart software is being developed by group of like-minded shop owners, programmers, designers, and consultants that think e-commerce could be and should be done differently.
Some "solutions" seem to be complicated programming exercises instead of responding to users needs, Zen Cart puts the merchants and shoppers requirements first. Similarly, other programs are nearly impossible to install and use without an IT degree, Zen Cart can be installed and set-up by anyone with the most basic computer skills. Others are so expensive ... not Zen Cart, its FREE!
Zen Cart will deliver the ultimate online shopping experience to your customers. Navigating through your merchandise offerings is a breeze with Zen Cart, the program provides several "Spotlight" lists in addition to the traditional category to product links. Once a product is added to the shopping cart, secure checkout is a simple 3-step process.
After providing the billing information, your customer chooses the shipping method. (multiple shipping methods including real-time internet shipping quotes are built-in) Next, a payment type is chosen from one of the popular payment modules. (PayPal and AuthorizeNet are just 2 of the included modules) Last, the customer reviews the order, shipping and payment choices, and confirms the order.
You are immediately notified of the order and your customer automatically receives an e-mail confirmation.
Zen Cart addresses many of the goals we set:
- make the program easy to set up
- make it easy to customize
- automate tasks, such as order confirmation
- make navigation simple
- built in promotions; discount coupons, gift certificates, newsletters and product notification
- offer single item specials and storewide discounts (group discounts and quantity discounts - Coming in future editions)
- built in Search Engine Optimization tools
- password protect the Administration Tool (administration "levels" - Coming in future editions)
- support multiple languages, currencies and tax structures
- In short, Zen Cart is shopping cart software the way it should have been all along.
Zen Cart gives web designers a robust and customizable electronic storefront thats easy to keep up-to-date with new features.
It provides usable, intuitive and unobtrusive purchase flows right out of the box based on proven industry best-practices - there are no major revisions required to get things right for your clients!
One of the secrets behind its power lies in our robust template system that "abstracts" the look-and-feel from the code and logic behind Zen Cart. This enables you to give clients a truly custom solution that integrates quickly and perfectly with their existing marketing websites.
Developers are able to deploy cutting edge solutions based on Zen Carts modern standards and technologies. Combining PHP server-side technology with the ability to choose from multiple databases on the back end (coming in future editions, thanks to ADOdb), results in flexible software that you can customize and modify to suit your needs. Minimum/suggested server requirements: PHP 4.1.x or higher (PHP 4.3.3+ for optimal performance), Apache 1.3.x and MySQL 3.2x.x or higher.
Enhancements:
- Two vulnerabilities related to cross site scripting (XSS) have been fixed.
- Officially certified for Paypal Express Checkout (only for North American Paypal accounts as of 20070101).
- Also includes several minor improvements and bugfixes.
