Combining EE + CodeIgniter on existing website?

Question

It’s been a while since my recent post, but I’ll be very happy, if I can get some help from you guys as well as to share an interesting scenario for other newcomers.

We have a website running on a domain like this:

• domain.tld
• domain.tld/section1
• domain.tld/section2

Our goal is to rebuild certain sections on CodeIgniter, since we need flexibility, which is not available in EE (not because of its limitation, but because of the details we stress on in the new version). Simply said, we try to accomplish:

• EE - domain.tld
• EE - domain.tld/section1
• CI - domain.tld/section2

Is there any reasonable way to do this? I know it’s a matter of “hacking” EE core and / or heavily customizing, but any ideas are more than welcome.

Thanks!

Answer 1

First thing: ExpressionEngine uses a modified version of CodeIgniter. Ellis Lab maintains their own branch of the main CodeIgniter code base, so expect to run into occasional issues between documentation and actual function.

Second thing: Go to your EE route config file at:

/system/expressionengine/config/routes.php

and you can go a head and mess about how you want. You should be able to set routes and use CodeIgniter class methods:

I've never done this in production, just messed with it at some point a few years ago. But give it a go, this could be your solution.
