Check if user exists on page load - El Forum - 12-18-2009

Hello!
I'm developing an membership system (based on tutorials, of course :-) ) and hit a wall... I'm saving the user id in a session variable and I want to check at each page load if that user id really exists, so I can update the 'login box' links. I have no idea how to to this...
Can somebody help me with this?
Thanks!

How are you saving it? In session?
If you use a MY_Controller you can just check it in the constructor of the MY_Controller.

Wow! That was fast! :-) Yes, I'm saving the id in a session variable. And thanks for reminding me of the MY_Controller which in fact, already is in my site... Again, from a tutorial
. Thanks again, Ben! That was my first silly post... More to come

Another suggestion would be to have your check inside a library and autoload it, so it get's automatically checked upon each page request. I think that's the way I usually go about this. Hope that helps.

That already happens automatically if you use MY_Controller.

Yep, in MY_Controller I load the user_model and check if the user_id from the session variable really exists in my database. If not, I destroy the session. Then, I extend MY_Controller with all my other controllers.
Thanks, guys!

I wasn't arguing that using MY_Controller wouldn't work, I know it does. I just wanted to share a different way to achieve the same goal
... I myself prefer the autoloaded library over using MY_Controller. Whichever is better or faster, I'll leave to the real CI experts.Cheers, Michiel
