Using codeigniter running locally on WAMP and dealing with sessions. I tried the default session handler, db session, native session and now db session. They all result in the same issue and I can't for the life of me figure it out.
The problem is that I am trying to set a session variable using a variable. I have confirmed the variable and have echoed it out and all is well in the controller. The controller calls on a view and the variable is there as well. The view calls on a uploader file and this is where the variable randomly gets set to "style.css" for some reason. If I set the session statically, say to "randyval", then it sticks. It's only when trying to use a variable that it breaks.
Using db session allows me to set using:
$some_val = $some_otherVal;
$_SESSION['sess'] = $some_val;
Only in the final page does echo $_SESSION['sess'] result in "style.css".
If however I do:
$_SESSION['sess'] = 'test';
Everything works as should.
Wouldn't ask unless I was at my wits ends... thanks for any input.
Color me stupid. :\ Turns out there was some bad html that was causing the problem(?). It had to do with, yeah, you guessed it, the header and more specifically where the "style.css" file was being called. Not sure why that was wrecking the session, but it indeed was. So, sorry for wasting everyones time, you can go home now.
You should work with CI sessions using Session Class
