how to use codeigniter for application

I'm new to codeigniter but I wanted to create an application like that of http://redbeacon.com or http://thumbtack.com.

What is the best approach to go about creating a site like one of the above and is there any open source application I can use as a skeleton? Even a tutorial on creating a site like that would be great!

Thank开发者_如何学JAVA you so much!

I doubt there are any specific open source solutions to your particular problem so I would say that you're going to have to create most of the site from scratch. That is, provided you have a good knowledge of PHP already.

If not, then I would suggest starting with some good php development books that will teach you the fundamentals of PHP.

For learning CodeIgniter you're quite lucky. One of the best parts about CodeIgniter is that it is very well documented.

For the quickest ramp up time I would take a hard look at Expression Engine. It is a commercial web publish tool that is based on CodeIgniter - so you get all the power of CI but with much greater ease of use. You can make pretty much any kind of site/web app with EE: showcase.
