+
+<h1>Shopping Cart Class</h1>
+
+<p>The Cart Class permits items to be added to a session that stays active while a user is browsing your site.  
+These items can be retrieved and displayed in a standard "shopping cart" format, allowing the user to update the quantity or remove items from the cart.</p>
+
+<p>Please note that the Cart Class ONLY provides the core "cart" functionality.  It does not provide shipping, credit card authorization, or other processing components.</p>
+
+
+<h2>Initializing the Shopping Cart Class</h2>
+
+<p><strong>Important:</strong> The Cart class utilizes CodeIgniter's
+<a href="sessions.html">Session Class</a>  to save the cart information to a database, so before using the Cart class you must set up a database table
+as indicated in the <a href="sessions.html">Session Documentation</a> , and set the session preferences in your <kbd>appliction/config/config.php</kbd> file to utilize a database.</p>
+
+<p>To initialize the Shopping Cart Class in your controller constructor, use the <dfn>$this->load->library</dfn> function:</p>
+
+<code>$this->load->library('cart');</code>
+<p>Once loaded, the Cart object will be available using: <dfn>$this->cart</dfn></p>
+
+<p class="important"><strong>Note:</strong> The Cart Class will load and initialize the Session Class automatically, so unless you are using sessions elsewhere in your application, you do not need to load the Session class.</p>
+
+<h2>Adding an Item to The Cart</h2>
+
+<p>To add an item to the shopping cart, simply pass an array with the product information to the <dfn>$this->cart->insert()</dfn> function, as shown below:</p>
+
+<code>
+$data = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'sku_123ABC',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty'&nbsp;&nbsp;&nbsp;&nbsp; => 1,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'price'&nbsp;&nbsp; => 39.95,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp; => 'T-Shirt',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'options' => array('Size' => 'L', 'Color' => 'Red')<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
+<br />
+
+$this->cart->insert($data);
+
+</code>
+
+<p class="important"><strong>Important:</strong> The first four array indexes above (<dfn>id</dfn>, <dfn>qty</dfn>, <dfn>price</dfn>, and <dfn>name</dfn>) are <strong>required</strong>.
+If you omit any of them the data will not be saved to the cart. The fifth index (<dfn>options</dfn>) is optional.
+It is intended to be used in cases where your product has options associated with it. Use an array for options, as shown above.</p>
+
+<p>The five reserved indexes are:</p>
+
+<ul>
+<li><strong>id</strong> - Each product in your store must have a unique identifier. Typically this will be an "sku" or other such identifier.</li>
+<li><strong>qty</strong> - The quantity being purchased.
+<li><strong>price</strong> - The price of the item.
+<li><strong>name</strong> - The name of the item.
+<li><strong>options</strong> - Any additional attributes that are needed to identify the product.  These must be passed via an array.
+</ul>
+
+<p>In addition to the five indexes above, there are two reserved words: <dfn>rowid</dfn> and <dfn>subtotal</dfn>.  These are used internally by the Cart class, so 
+please do NOT use those words as index names when inserting data into the cart.</p>
+
+<p>Your array may contain additional data.  Anything you include in your array will be stored in the session.  However, it is best to standardize your data among
+all your products in order to make displaying the information in a table easier.</p>
+
+
+<h2>Adding Multiple Items to The Cart</h2>
+
+<p>By using a multi-dimensional array, as shown below, it is possible to add multiple products to the cart in one action.  This is useful in cases where you wish to allow
+people to select from among several items on the same page.</p>
+
+
+<code>
+$data = array(<br />
+
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty'&nbsp;&nbsp;&nbsp;&nbsp; => 1,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'price'&nbsp;&nbsp; => 39.95,<br />

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty'&nbsp;&nbsp;&nbsp;&nbsp; => 1,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'price'&nbsp;&nbsp; => 29.95,<br />

+
+
+<h2>Updating The Cart</h2>
+
+<p>To update the information in your cart, pass an array containing the product ID and quantity to the <dfn>$this->cart->update()</dfn> function:</p>
+
+
+<code>
+$data = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp; => '123XYZ',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty' => 3<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
+<br />
+
+$this->cart->update($data);
+
+</code>
+
+<p>Just as you can when inserting, you may use a multi-dimensional array in order to update multiple items simultaneously:</p>
+
+
+<code>
+$data = array(<br />
+
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
