I have come along something i could not solve for so long.
i have created a script in php that unsets one single session variable, However the page stats the session Here is my code for the page :
<?php
session_start();
require_once("../header.php");
if($_SESSION['user']) {
unset($_SESSION['user']);
echo "you succesfully logged out.";
header("Refresh:5; url=http://www.webmasteroutlet.com");
} else {
echo "you are already NOT LOGGED IN right now.";
}
require_once("../footer.php");
?>
That is the whole code on this page. and it always prints out "you are already NOT LOGGED IN right now." $_SESSION['user'] is assigned true in login.php page and i have session_start(); at the very beginning of the page right after the <?php opening.
The session variable is recognized at all other files with php extension and that is the only single file that it is not working on. I also tried
<?php
session_start();
echo $_SESSION['user'];
?>
and it does not print anything. It simply skips that line and does nothing. What am i doing wrong ?
Thank You very much for your help.
this is the header.php code
<?php
session_start();
require("config.php"); // that only contains connection to the database and it is successful.
if(isset($_SESSION['user'])==1){
echo "<div id=\"topnav\" class=\"topnav\"><span>".$_SESSION['username']."</span> <span>LOGOUT</span></div>";
}
else if ($_SESSION['admin']) {
echo "<div id=\"topnav\" class=\"topnav\">"."<span>".$_SESSION['adminusername']."</span> ";
echo "<span>LOGOUT</span></div>";
}
else if ( !isset($_SESSION['user'])) {
require ($_SERVER['DOCUMENT_ROOT']."/users/login.php");
}
require("search.php");
?>
i think you need the if is set and make sure you pass the sessions data to this page it looks like your unsetting this
Try this:
<?php
session_start();
require_once("../header.php");
if(isset($_SESSION['user'])) {
echo "User.".$_SESSION['user']." you are being logged out";
unset($_SESSION['user']);
header("Refresh:5; url=http://www.webmasteroutlet.com");
} else {
echo "You are not logged or var SESSION doesnt exist";
}
require_once("../footer.php");
?>
If still doesnt work, try deleting the require_once lines(for debug).
Justin, I think you're not setting the $_SESSION['user']. That'd be the reason why you're getting NULL when you vardump.
One other possibility, although I'm limited to the scripts you provided, would be that you made it possible for a person to login through $_SESSION['admin'] as well as $_SESSION['user']. If this is the case you'd have to change the script to:
if(isset($_SESSION['user'])) {
unset($_SESSION['user']);
echo "user succesfully logged out.";
}elseif(isset($_SESSION['admin'])){
unset($_SESSION['admin']);
echo "admin succesfully logged out.";
}else{
echo "you are already NOT LOGGED IN right now.";
}

I have a page where I set a value to a SESSION but when I redirect to another page
ex. index.php that value I put to that SESSION doesn't exist anymore!
<?php
session_start();
// this is the page where I set a value to a SESSION called var!
$SESSION['var'] = "hello";
if(isset($SESSION['var'])){
echo "Yes it is";
header("location: test.php");
exit();
}
else {
echo "No it isnt";
}
?>
And this is the test.php where I get the SESSION undefined error!
<?php
session_start();
if(isset($SESSION['var'])){
echo "Yes it is";
}
else {
echo "No it isnt";
}
?>
Ass you can see, I put session_start(); in both pages but still nothing!
Any help would be much appriciated,
thank you!
P.S Im using XAMPP
To access session variables you need to access the $_SESSION. Change $SESSION to $_SESSION. Hope this helps.
I'm trying to integrate a php login script that I have working, but I can't seem to get simple php calls going on a page. On this user profile page, I want to simply have the user name displayed (mysql field is "name"). The user is logged in and the session carries through, but on this page, all I see is the text "Here is your profile info..." What might be wrong in the code to prevent the user name from displaying?
<?php
include_once('classes/check.class.php');
include_once('header.php');
if( protectThis("*") ):
if(!isset($_SESSION)) {
session_start();
}
if(isset($_SESSION['jigowatt']['name'])) {
echo "You're name is: " . $_SESSION['jigowatt']['name'];
}
?>
<br />
Here are is your profile info...
<?php
else :
?>
<div class="alert alert-warning">
<?php _e('Only signed in users can view what\'s hidden here!'); ?></div>
<?php
endif;
include_once('footer.php');
?>
For check session is set already use session_id() Also check you have set $_SESSION['jigowatt']['name'] already with empty()
if(session_id() == '') {
session_start();
}
if(!empty($_SESSION['jigowatt']['name'])) {
echo "You're name is: " . $_SESSION['jigowatt']['name'];
}
else {
echo 'username is empty';
}
You need to put session_start(); at the very top of the page. No white space can be put before that. Try if that works.
First you need to write the sessions at the very top of the page if it works than okay else you can try this.
Just append this 2 function before and after the session_start();
Like this
ob_start();
session_start();
ob_end_clean();
I created two files
1.php
2.php
which are in the same folder(i am using xampp).
In 1.php used session_start() and also used $_session['name']=abc. Then i opened 2.php to check whether session was created or not
2.php:
<?php
if(isset($_session['name'])){
echo $_session['name'];
}
else{
echo "no session found!!";
}
?>
and it keeps on saying "no session found!!"
Plz help ...
I searched a few sites n they say that by default d session is for whole folder containing
d script and session_set_cookie_params($lifetime,'/') (where $lifetime=60*60) is also nt helping.
On d other hand if at d end of1.php i use require("2.php") then abc is displayed.
What you have done is right in 1.php,
however, 2.php must start the session before using it.
2.php
<?php
session_start();
if(isset($_SESSION['name'])) {
echo $_SESSION['name'];
}
else{
echo "no session found!!";
}
?>
You're missing session_start() at the top of your 2.php file which is needed to access $_SESSION variables.
<?php
session_start(); // missing
if(isset($_SESSION['name']))
{
echo $_SESSION['name'];
}
else
{
echo "no session found!!";
}
?>
You need to call session_start(); again at the top of every page where you want to access $_SESSION variables, not only on the page where you want to initiate the session.
<?php
session_start();
if(isset($_SESSION['name'])){
echo $_SESSION['name'];
}else{
echo "no session found!!";
}
?>
Today my question is how do i get people to roam the site with out logging in, I have tryed loads and loads of diffrent ways, when i tried to roam my site when i was not logged in it just used to redirect me to my login page, but when i tried my most recent code (the one below this post) it just comes up with this error, Undefined index: username in E:\wamp\www\login\main.php on line 6
<?php
ob_start();
//session
session_start();
$_session_username = $_SESSION['username'];
if (!isset($_session_username))
{
echo"Hello i'm sorry to say this but your not logged in <a href='login.php'>Log-in</a>";
exit();
}
else
{
echo "hello, ".$_session_username." <a href='logout.php'>Log out</a>";
}
ob_end_flush();
?>
Put simply you were on the right path, however you can't assign $_SESSION['username'] to a variable and then check if it is set. You first need to check if the $_SESSION['username'] is set, and then if it is you are able to assign it to a variable.
<?php ob_start();
//session
session_start();
if (!isset($_SESSION['username']))
{
echo"Hello i'm sorry to say this but your not logged in <a href='login.php'>Log-in</a>";
exit();
}
else
{
$_session_username = $_SESSION['username'];
echo "hello, ".$_session_username." <a href='logout.php'>Log out</a>";
}
ob_end_flush();
?>
How it should work:
Index.php is the secured page. It includes check.php, which checks if you have a session = good. If it hasn't, you're not logged in -> log off, remove session. But it doesn't work, it always logs off, like I didn't log in...
index.php
include ‘check.php’;
echo "logged in";
check.php
session_start();
if($_SESSION[‘login’] != ‘good’) {
unset($_SESSION[‘login’]);
unset($_SESSION[‘name’]);
header(‘Location: login.php?logoff’);
exit();
}
Login.php
if(isset($_POST[‘login’])) {
$gb = array();
$gb[‘user1’] = ‘pass1’;
$gb[‘user2’] = ‘pass2’;
if(isset($gb[$_POST[‘username’]]) && $gb[$_POST[‘username’]] == $_POST[‘password’])
{
$_SESSION[‘login’] = ‘good’;
$_SESSION[‘name’] = $_POST[‘name’];
header("Location: index.php");
} else {
header("Location: login.php?wrongpass");
}
} else { ?>
Login Form
<?php } ?>
I hope someone can help me!
You should verify you started the session in login.php.
Put session_start(); in all the pages
You need to have session_start() at the top of all the pages, you havent shown the session start for your login page.
(Thanks to Danny for proving I cant type)
Check that you have register_globals is On in your php.ini
First check on the pages you want to use session variables session is start or not and if session is not stat then start it.
and this is the very first line in the php file.
Code for the session checking is :
if(!session_id())
{
session_start();
}
if($count==1){
session_start();
$_SESSION['Username'] = $UserName;
$_SESSION['Password'] = $password;
UpdateOnlineChecker($Session);
header( "Location: http://". strip_tags( $_SERVER ['HTTP_HOST'] ) ."/newHolo/" );
exit;
}
else {
echo "Wrong Username or Password";
}
Look at my code. It checks if the statement is true (for me, if there is one row with a query statement i execute). Then i start a session and basically Ill define global session variables, sned out a query to my database to update the session and then refer through.
you are missing a session_start(); in your if true block.
Use one for action document such as index.php there is code:
session_start();
if(isset($_POST['login']) && isset($_POST['password'])){
// login
header('Location: (here is some page)');
}
if(!isset($_SESSION['user']){
// #todo some action
} else {
require_once('login.php');
}
if(isset($_GET['logout'])){
unset($_SESSION['user']);
header('Location: (here is some page)');
}
I think problem is header:
('location:------.php);
Your hosting server doesn't run this.
You can use this:
echo "<script>window.location.href='-----.php'</script>";
