Session doesn't work

General PHP Help
#1

Hello

The problem is, Session lost when I refresh the page or when I click on any link on the sidebar

So when I log in, everything working fine. I get the details from username the session is working. But when I refresh or click on one of the links on the sidebar redirect me to the index page. If I switch off the SESSION then the link is working but no session data. on that page.

So the SESSION is not going to the next page on the admin area.

Can you help me with it?

So from the Login page to admin_dashboard.php working fine but from admin_dashboard.php to admin_user_setting.php, SESSION is lost.

Hopefully, you can help me.

Thank in advance

// login.php

Do you have a session_start() statement on each page that sets or references a $_SESSION variable?

Also, every header() redirect needs an exit/die statement after it to STOP program execution.

The ONLY thing you should store in a session variable when the user logs in is the user’s id. You should query on each page request to get any other user information, so that any changes mode to the user information will take affect immediately (on the next page request after the change), without needing the user to re-login.

Hi
Thanks your answer
I use session_start() on each page but can you help me with the rest?

#4

Yes, but is it running without error on each page? Do you have php’s error_reporting set to E_ALL and display_errors set to ON, preferably in the php.ini on your system, so that php would help you by reporting and displaying all the errors that it detects?

#5

This is the code on each admin page:

<?php session_start();

if($_SESSION['user_email']=="" OR $_SESSION['role']=="User"){

    header('location:../index.php');
}?>

If the header locations (header(‘location:…/index.php’):wink: active, automatically send me to the index.php

If I delete, redirect me to the correct page but I get this message : Notice** : Undefined index: user_email in C:\xampp\htdocs\testCopy\includes\admin_user_settings.php on line **5

The SESSION doesn’t send the details from the admin_dashboard to another page!!

#6

Hi
can you help with it?

#7

You need to check if the key isset

if ( isset( $_SESSION['user_email']))

or

if ( empty( $_SESSION['user_email']))
#8

From login page to admin page , workng fine but from admin to another page the session is lost.
redirect me to index.php
This is the code on the 3rd page:

<?php session_start(); if($_SESSION['user_email']=="" OR $_SESSION['role']=="User"){ header('location:../index.php'); } ?>
#9

And session_start is on every page?

#10

Yes

<?php include "db.php";?> <?php session_start(); if($_SESSION['user_email']=="" OR $_SESSION['role']=="User"){ header('location:../index.php'); } ?>
