Hello i am having problems holding sessions from page to page, code worked on my previous servers running php5 but not on my recent server, i am wondering whether its a bug?
<?php
session_start();
$_SESSION['session'] = $_POST['session'];
header("location: www.mysite.com/page1.php");
?>
<?php
session_start();
echo "Good morning" . $_SESSION['session']; //returns empty session always.
?>
ANy ideas? session is held on first page but not on the second.
In case you missed it, make sure you do a session_start() at every page you're using the $_SESSION variable.
You should check your php.ini file and see what's going on.
Make sure session.use_cookies = 1 and session.save_handler = files.
Use this test page to see whether it's a general PHP problem or just your code.
<?php
session_start();
if(isset($_SESSION)){
echo "Session variable exists<br/>";
if(!isset($_SESSION['test'])){
$_SESSION['test'] = "Success!";
echo "Variable has been set, refresh the page and see if stored it properly.";
}else{
echo $_SESSION['test'];
}
}else{
echo "No session variable has been created.";
}
?>
If that worked, then it's got to do with your code.
If you're setting your session variable to $_POST['session'] am I to assume you submitted a form with an input with the name session?
This setup should work.
index.php
<form action='page0.php' method='POST'>
<input type='hidden' name='session' value='SPAAAAACE' />
<input type='submit' />
</form>
Page0.php
<?php
session_start();
$_SESSION['session'] = $_POST['session'];
header("location: www.mysite.com/page1.php");
?>
Page1.php
<?php
session_start();
echo "Good morning" . $_SESSION['session'];
?>
For completeness and debugging purposes
In case you are using cookie-less sessions, you have to manually add the SID (session id) to the header redirect like this
header("location: www.mysite.com/page.php?".htmlspecialchars(SID));
If the problem still persists, it could be a permission issue.
Maybe you're not allowed to read the session file stored on the server?
Update: OP commented that it was a permission issue and the problem is now resolved
Turn on error reporting temperately with:
error_reporting(E_ALL) This may spit out an error related to your problem. Most likely an undefined index session notice.
You should always have a check in place on Super Globals.
<?php
session_start();
$_SESSION['session'] = (isset($_POST['session']))?$_POST['session']:null;
header("Location: www.mysite.com/page1.php");
die;
?>
Your code seems correct though I'm pretty sure $_POST['session'] is empty.
You should try this :
<?php
session_start();
$_SESSION['session'] = 'John Doe';
header("location: www.mysite.com/page1.php");
?>
<?php
session_start();
echo "Good morning" . $_SESSION['session']; //returns empty session always.
?>
To see if this works or not. I guess it will.
IF not, take a look at your cookies, maybe they are disabled.
Then, if it works, I probably because $_POST['session'] is null or empty, are you sure you posted something like <input type="text" name="session" /> ?
You need to pass the session id with the redirect.
Also make sure you use session_start() at the top of EVERY page that needs a session
First try using
<?php session_start();
instead of
<?php
session_start();
If the problem still exists, then open your script in Netbeans editor and see whether any unexpected characters found at very beginning of the the script.
In addition, please make sure that $_POST['session'] has a value to assign in $_SESSION['session'].
You will have to call
session_start();
on the first line of every page you want to retain the session in

Iam having issues echoing the session username and have no idea were to start any more cause every thing i have tried keeps saying string to array conversion but idk how to get this to correctly work. here is the code that would check for the loged in saying you logged in would you like to log out.
if(isset($_SESSION['username'])&& !empty($_SESSION['username'])){
echo "<P id='loged'>your loged in would you like to log out</p>";
echo'log out';
}else{
include 'logform.php';
}
You probably want to call session_start() before the $_SESSION variable will be available.
You just want to echo the username?
echo "Hello " . $_SESSION['username];
I suppose the following answers your question...
echo $_SESSION['username'];
...but you will also want to use session_start() first.
Also, no need to use isset() and !empty(), as empty() checks if it is set first. All you really need is:
if(!empty($_SESSION['username']))
You forgot to mention session_start() in the begining.
session_start(); //add this in the begining of the file.
echo $_SESSION['username']; //this will display username
Try this:
call the function session_start() at beginning of the page and then check the $_SESSION array using
echo '<pre>';
print_r($_SESSION);
after that you see all the indexes set in session variable.
Thanks
Why I am getting an empty array of the session when I am trying a var_dump in another page?
In the server, the session is stored without any content, only with the name of the id.
With cookies all works well. Sometimes (yes, sometimes), I restart the server, and then, the sessions works well too. What may cause this issue?
Maybe a bug of the php 5.1.6? or a problem in the config of the server?
index_2.php
<?php
session_start();
$_SESSION['xxx'] = "tessstsse";
var_dump($_SESSION);//here show the correct session
header( 'Location: index_3.php');
index_3.php
<?php
session_start();
var_dump($_SESSION);
The output of this will be:
array
empty
Give this a try.. if this works I'd re examine your code else it is probably an issue with your server...
page1.php
<?php
session_start();
$_SESSION['auth'] = "true";
$_SESSION['superhero'] = "batman";
?>
Click here
page2.php
<?php
session_start(); // start the session before using it
//echo $_SESSION['auth']; // will output 'true'
print_r($_SESSION);
?>
destroy.php
<?php
session_start(); // start the session before using it
session_destroy(); // deletes the current session..
?>
I have the web server without space to store the session content.
0% of free space. Delete some data and the problem is solved.
I have created a php session and have assigned data like so
session_start();
$_SESSION['desd']=$imgD;
When i try to retrieve it on other page i get nothing.
this is what i have done on second page,
session_start();
$_imgname = $_SESSION['desd'];
How to do that?
The code is valid, assuming that the variable $imgD is defined (var_dump is one way of checking this, but print or echo may also work).
Check to ensure that cookies are enable in your browser.
Also, be sure that session_start() comes near the top of your script, it should be the first thing sent to the client each time.
To test a session, create "index.php" with the following code:
<?php
session_start();
if(isset($_SESSION['views']))
$_SESSION['views'] = $_SESSION['views']+ 1;
else
$_SESSION['views'] = 1;
echo "views = " . $_SESSION['views'];
?>
Reload the page several times and you should see an incrementing number.
An example of passing session variables between two pages is as follows:
PageOne.php
<?php
session_start();
// makes an array
$colors=array('red', 'yellow', 'blue');
// adds it to our session
$_SESSION['color']=$colors;
$_SESSION['size']='small';
$_SESSION['shape']='round';
print "Done";
?>
PageTwo.php
<?php
session_start();
print_r ($_SESSION);
echo "<p>";
//echo a single entry from the array
echo $_SESSION['color'][2];
?>
For simplicity put PageOne.php and PageTwo.php in the same directory. Call PageOne.php and then PageTwo.php.
Try also tutorials here, here, and here.
If you call session_start(), the server gets the session ID from cookies.
Maybe something is wrong with the cookies because the code is valid.
I'm writing a user login system, and I (like so many others) am having a problem with my sessions.
Here's the pointer from the login script when the inputs are validated:
session_start();
$_SESSION['id']=$id;
header('location: memberhome.php');
Here's the first thing on memberhome.php:
<?php
session_start();
$id=$_SESSION['id'];
?>
And later in memberhome.php:
You are logged in as: <?php echo $id; ?>
The problem is $_SESSION['id'] is apparently empty so the echo $id prints nothing.
An alternate that also does NOT work:
//removed session_start and $_SESSION bit from the top
You are logged in as: <?php session_start(); echo $_SESSION['id']; ?>
NOW, here's the weird part. This method DOES work:
You are logged in as: <?php echo session_start();$_SESSION['id']; ?>
You can see the session_start() is moved AFTER the echo. This works when the page loads from the login script. However, upon refresh, it does NOT work once again.
I've tried a bunch of alternatives and spent a few hours searching for answers in previous questions. I also looked at my phpinfo() for something fishy and found nothing. This is entirely what my progress is hinging on. Thanks!
First of all, please enable debugging:
error_reporting(E_ALL);
ini_set('display_errors', '1');
Second, session_start() needs to be at the top of the page. So the line you wrote;
You are logged in as: <?php echo session_start();$_SESSION['id']; ?>
will never work.
The following line needs to be on top of the page, before any HTML etc.
<?php
session_start();
$id=$_SESSION['id'];
?>
Have you tried:
print_r($_SESSION);
to examine the contents of the session?
Make sure you're calling session_start() before you output anything on the page. The standard cookie-based sessions require some header information to be exchanged, which must be done before you send any content.
You're most likely running into output buffering, which is why it sometimes works and other times it does not. Generally speaking, stick to starting the session before any output is generated, you'll find your code works better.
use
ob_start(); #session_start();
on the top of the both page
My website doesn't start a session when I visit, I don't know why but my website works like this:
<?php
session_start();
$title = "Home";
include("include/header.php");
include("include/functions.php");
?>
...HTML stuff here...
<?php
include("footer.php");
?>
But when I check with Cookies (add-on for Firefox) there are no sessions started... I used session_regenerate_id(); but it doesn't work at all.
It fails to log in since there are no sessions, I do not have any session_destroy() in my website, only in the logout.
But funny thing is, when I login (without refreshing or navigating just yet) and then click on the logout button, there is a session on my website, then when I log in again, it tells me that I am logged in BUT if I login and navigate or refresh, it doesn't tell me that I'm logged in since there are no sessions...
Logout:
<?php
session_start();
session_destroy();
setcookie("cookie-name", "", time()-60, "", "", 0);
header("Location: ../index.php");
exit;
?>
What do I do?
You must have session_start() at the beginning of every file that is being accessed and uses sessions. The name is misleading, session_start() actually doesn't start a new session but initialzes PHP session menagment.
Not sure if it's related, but there was a strange PHP quirk that required the SESSION_START() to be on the line immediately below the <?php tag. Something about whitespace and extra things above the session used to make it go haywire for me. I've been using Zend of late, which avoids that issue with its own session handling system.
You might try doing a print_r($_SESSION) to see if there's anything in the session array at all.
It's probably because you are not setting a session in either of the examples you have given, you have to have a line like the one below to actually create a session, and then to access the session variables on all subsequent pages you need session_start();
$_SESSION['example'] = 'something';
It doesn't look like your setting anything in the session or the cookie.
If you want to pass information around in the session you'll need to assign the necessary values in the $_SESSION variable.
For example on your main page you can do:
<?php
session_start();
$_SESSION['myVariable'] = "my text";
?>
And then on any subsequent pages you can access the variable you've set.
<?php
session_start();
echo $_SESSION['myVariable']; //This will print "my text"
?>
