Quick Shop supports any WordPress that has the Sidebar Widgets installed, really. It adds a SideBar widget that shows the user what
they currently have in the cart and allows them to remove the items, not to mention a TinyMCE button to easily allow you to add products to your posts/pages.
Also, you will need to make your own CSS for this. I’ve included enough classes/ids for you.
Features:
<ul>
<li>
Inventory listing tied in to TinyMCE
</li>
<li>
Integrates automatically with CFormsII (and uses CFormsII API so you can edit it easily yourself)
</li>
<li>
Full range of formatting for widget layout in Admin -> Options -> Quick Shop
</li>
<li>
Shopping cart Widget
</li>
<li>
Checkout page
</li>
<li>
Ability to create different product options in a drop-down
</li>
<li>
WordPress MU compatible
</li>
</ul>
One of my clients required a quick and dirty shopping cart for WordPress. The background:
<ol>
<li>
They had more than one product per post
</li>
<li>
They only wanted orders to be sent via email
</li>
<li>
They only needed EFT (Electronic Fund Transfer – like Direct Debit or Internet Banking)
</li>
</ol>
Thus, Quick Shop was born thanks to the excellent way in which the WordPress Plugin API is set up.
List of possible future features:
<ul>
<li>
AJAX implementation
</li>
<li>
Inventory quantities
</li>
</ul>
Please be aware that I’ll only be updating this if I need to or if I’m paid to. Feel free to come on board and contribute!
