Typically this will be an “sku” or other such identifier.</li>
|
||
<li><strong>qty</strong> - The quantity being purchased.</li>
|
||
<li><strong>price</strong> - The price of the item.</li>
|
||
<li><strong>name</strong> - The name of the item.</li>
|
||
<li><strong>options</strong> - Any additional attributes that are needed to identify
|
||
the product. These must be passed via an array.</li>
|
||
</ul>
|
||
<p>In addition to the five indexes above, there are two reserved words:
|
||
rowid and subtotal. 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>

<h4><a class="toc-backref" href="#id7">What is a Row ID?</a><a class="headerlink" href="#what-is-a-row-id" title="Permalink to this headline">¶</a></h4>
|
||
<p>The row ID is a unique identifier that is generated by the cart code
|
||
when an item is added to the cart. The reason a unique ID is created
|
||
is so that identical products with different options can be managed
|
||
by the cart.</p>
|
||
<p>For example, let’s say someone buys two identical t-shirts (same product
|
||
ID), but in different sizes. The product ID (and other attributes) will
|
||
be identical for both sizes because it’s the same shirt. The only
|
||
difference will be the size. The cart must therefore have a means of
|
||
identifying this difference so that the two sizes of shirts can be
|
||
managed independently. It does so by creating a unique “row ID” based on
|
||
the product ID and any options associated with it.</p>
|
||
<p>In nearly all cases, updating the cart will be something the user does
|
||
via the “view cart” page, so as a developer, it is unlikely that you
|
||
will ever have to concern yourself with the “row ID”, other than making
|
||
sure your “view cart” page contains this information in a hidden form
|
||
field, and making sure it gets passed to the <code class="docutils literal"><span class="pre">update()</span></code> method when
|
||
the update form is submitted. Please examine the construction of the
|
||
“view cart” page above for more information.</p>
