beta invite code + codeigniter

Question

I'd like to limit access to my app (in Codeigniter) for beta users. Wondering if anyone knows of a library, spark or other option that can help me get started.

Would prefer not to reinvent the wheel if there's something out there already. My searches on Google and other resources haven't yielded anything.

Answer 1

Just use ANY of the Authentication libraries - and add a field called "Beta Code" on the registration page. If "beta code = your secret beta code" then allow registration. If the code is incorrect, then dont allow them to sign up.

You could extend if further when you are ready to go live, and turn it into a "promotion code", and if code = X, then apply 10% discount, extra free time etc (if this is a paid service when you go live).
