Session variables not working php

Question

Here are the code of my login page where the login script checks for the authenticity of the user and then redirects to inbox page using header function    lt  php session start     include once  config php     user htmlentities stripslashes   POST  username       password htmlentities stripslashes   POST  password         Some query processing on database      if   id user fetched lt   id max fetched   amp  amp    id user fetched  0      SESSION  loggedIn      yes       header  Location http   xyz inbox php u  id user fetched          echo  Login Successful        else          echo  Invalid Login           echo  lt br   gt   lt a href  index html  gt Click here to try again lt  a gt               else      echo mysqli error  Login Credentials Incorrect             gt    The inbox php page looks like this    lt  php session start     echo  SESSION      SESSION  loggedIn    if   SESSION  loggedIn       yes    echo  message    you must log in to see this page      header  location login php         REST OF THE CODE    gt    Now with the above code  the inbox php always shows the output   SESSION you must log in to see this page  Which means that either the session variable is not being setup or the inbox php is unable to retrieve the session variable  Where am i going wrong

Maybe if your session path is not working properly you can try session save path path to any folder   function as alternative path  If it works you can ask your hosting provider about default path issue

I had the same issue for a while and had a very hard time figuring it out  My problem was that I had the site working for a while with the sessions working right  and then all of the sudden everything broke   Apparently  your session save path    for me it was  var lib php5   needs to have correct permissions  the user running php  eg www-data needs write access to the directory   I accidentally changed it  breaking sessions completely   Run sudo chmod -R 700  var lib php5  and then sudo chown -R www-data  var lib php5  so that the php user has access to the folder

Make sure session start    is called before any sessions are being called  So a safe bet would be to put it at the beginning of your page  immediately after the opening  lt  php tag before anything else  Also ensure there are no whitespaces tabs before the opening  lt  php tag    After the header redirect  end the current script using exit     Others have also suggested session write close    and session regenerate id true   you can try those as well  but I d use exit        Make sure cookies are enabled in the browser you are using to test it on    Ensure register globals is off  you can check this on the php ini file and also using phpinfo    Refer to this as to how to turn it off    Make sure you didn t delete or empty the session    Make sure the key in your   SESSION superglobal array is not overwritten anywhere    Make sure you redirect to the same domain  So redirecting from a www yourdomain com to yourdomain com doesn t carry the session forward    Make sure your file extension is  php  it happens         PHP session lost after redirect

The other important reason sessions can not work is playing with the session cookie settings  eg  setting session cookie lifetime to 0 or other low values because of simple mistake or by other developer for a reason    session set cookie params 0
