Keeping It DRY

[eluser]CI-Newb[/eluser]
I was reading over this article: Keeping It DRY . I noticed it was published in 2010, Codeigniter has obviously gone through changes since then. My question: Is this still the most efficient way to accomplish this? Basically my entire app will require the user to be logged in. I would like to make a call "if user is logged in, continue, else redirect" and I would like to avoid having to put this call in every controller / function. Please Advise.

Thank you.

Hello CI-Newb!

Maybe yes, I still use the same approach now.
You should give a look to many other libraries for authentication here http://blog.pisyek.com/2011/11/5-best-au...deigniter/ for finding the best one for your.

Autoload user model, in <b>__construct</b> method check if user ID is present in session userdata.

Same method can do the redirect, just make sure you allow everyone to see the login page

I usually follow DRY in the sense of if I know I have to repeat the code multiple times, it will go in it's own function or in a for loop.
