http://www.excellenc…omobile.com.sg/ is an online used-car catalog site i have developed fully using Yii, with the Yii Skeleton Application as a base and various extensions (like the Image extension to handle thumbnail generation) etc.
The entire site was developed as a freelance project for a local used-car exporter (local where i live, which is in Singapore).
The site enables public user registration and login as well as search for the catalog section.
For the administrator interface (which i will be unable to show you), i allowed the admin user to add/edit/delete cars and users.
I also modified the "JEditable" extension that came with the Yii Skeleton Application to use TinyMCE, so the entire site, when logged in as an Admin user, has a "click to edit" CMS functionality.
Do take a look around and give us your comments. I would be happy to share any pieces of code you are interested in if possible, though actually the site was developed in a little bit of a hurry so some of the code may not be optimal and/or easily reusable.
