Smart Cart 2 - javascript jQuery shopping cart plugin




Overview:

Smart Cart 2 is a flexible and feature rich jQuery plug-in for shopping cart. It makes the add-to-cart section of online shopping much easy and user friendly.
It is very easy to implement and only minimal HTML required. The selected items in the cart are accessible as an array of product/quantity pair delimited with ‘|’ on submit form or when checkout event is triggered. Smart Cart 2 have a simple and compact design with tabbed interface to saves space.
To avoid complexity I haven’t implemented built-in Ajax support, but using the events you can easily implement the Ajax features. The product list is more dynamic with built-in search and category filter. Template option gives you freedom to customize the product details display on product list and cart. It is also having option to show the product image and its expanded tool tip.

Some more details & descriptions:


1. How to show more product details on product list / How to customize Template?

<input type="hidden" pimage="products/product1.jpg" pprice="2299.99" pdesc="The Intel Core Duo." pcategory="Computers" pname="Apple MacBook Pro" pid="100"
product_sku ="SDK334455">

Here added a new pseudo attribute "product_sku".
Describes below is how to apply product list template, and the highlighted part will be replaced with the SKU of specified for corresponding product.

Specify your attribute by wrapping it with <%= and %> on the templates (productItemTemplate, cartItemTemplate) will be replaced with the value of the attribute on the product list or cart when displayed.
Example: <%=YOUR_ATTRIBUTE_NAME%>

  var productTemplateWithSKU = '<strong><%=pname%></strong><br />
          Category: <%=pcategory%><br /> 
      <small><%=pdesc%></small><br /><strong>Price: <%=pprice%></strong><br />

      <strong>SKU:  <%=product_sku%></strong>';
  // calling Smart cart
  $('#SmartCart').smartCart({productItemTemplate: productTemplateWithSKU });

2. How to enable category filter?

Category filter is an automatic option and you can enable or disable by specifying the Option parameter: enableCategoryFilter to true/false
Also the product category attribute should present the hidden element, if it is empty or null the category filter will be disabled. The category select box is filled automatically by reading the category attribute.

So to enable category filter you have to do only 2 things:
1. Enable it on option parameter enableCategoryFilter : true (true by default).
2. Specify category attribute in the hidden element.

<input type="hidden" pimage="products/product1.jpg" pprice="2299.99" 
 pdesc="The Intel Core Duo." pcategory="Computers" pname="Apple MacBook Pro" 
 pid="100">
