PHP Session Seemingly Not Working

PHP session seemingly not working

You know that you've got to write session_start() before you use the $_SESSION variable in any request, right? It looks like you haven't put it in index.php anywhere.

PHP $_SESSION not working

You need session_start() at first.

PHP Sessions Troubleshooting

Okay, I've figured it out! Thanks everyone for your suggestions, turns out I need to learn to read error logs ...

I use vestacp and apparently it defaults the PHP sessions to /home/admin/tmp, and I'm not sure how but you're not able to change that (which I did). There was another problem though, the ownership and permissions weren't correct for that folder. Turns out all I needed was a chmod -R 700 /home/admin/tmp and chown -R root /home/admin/tmp - which I already tried on the other folder but it didn't allow that.

Btw, here's the error line that triggered the 'oh what the hell I can't change the session directory':

Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/home/admin/tmp) in Unknown on line 0

$_SESSION not seeming to work

You HAVE to start the session every time you intend to use it. (preferably at the beginning of the page)

<?php session_start();?>

PHP $_SESSION variable not working first time

I was using AWS Elastic Beanstalk to run this web app. I didn't think this matter but apparently it did. It turns out that sessions don't work the same as they do on localhost since you are dividing your servers. I needed to enable sticky session within the load balancer.

Sessions not showing but are definitely there as shown from next page

Okay... Sorted it out... Please read...

Even though this is a new page, the code is sort of coming off layers of other files...

I didn't think this should have been an issue...

(I had thought that each page needed it's own session_start() but for some reason they don't and all of them apparently are based off one page... bit complicated to explain - suffice it to say that I am trying to sort out someone else's code :-P)

Anyway, I went through all the files that are connected to this one, deleted all the session_start()s from them besides for the primary one. Now it's working fine.

The data now displays perfectly!

Question:
Does anyone have an explanation for this?

Why does having too many session_starts() cause problems?

PHP Session data not being saved

Thanks for all the helpful info. It turns out that my host changed servers and started using a different session save path other than /var/php_sessions which didn't exist anymore. A solution would have been to declare ini_set(' session.save_path','SOME WRITABLE PATH'); in all my script files but that would have been a pain. I talked with the host and they explicitly set the session path to a real path that did exist. Hope this helps anyone having session path troubles.
