Hi,

I am developing a website. In Login form , on successful login of user, i had created session variable $_SESSION['username'] and redirected to second page. In second page when i checked , isset($_SESION['username']) is returning false.

This is the first website I am developing. Do I have to change any settings in php.ini for sessions to work?

For us to *really* help and not just guess, we need to see your code. Please post it using [code] tags.

My guess is you're not starting the session with session_start() .

Here is the code:

loginpage.php

Code:

<?php
session_start();
require('config.php');

if($_POST['submit'])
{
  $username = $_POST['name'];
  $password = $_POST['password'];
  $mysql = mysql_connect($dbhost,$dbuser,$dbpassword);
  mysql_select_db($dbdatabase,$mysql);
  $loginsql = "select * from logins where username='" . $username ."' and password='". $password. "';";
  $loginres = mysql_query($loginsql);
  $numlogin = mysql_num_rows($loginres);
  $row = mysql_fetch_assoc($loginres);
  if($numlogin==1)
   {
    session_register('USERNAME');
    session_register('SESS_LOGGEDIN');
    $_SESSION['USERNAME'] = $row['username'];
    $_SESSION['SESS_LOGGEDIN'] = 1;
    if(isset($_SESSION['USERNAME']))
     {
       header("Location:".$config_basedir."index.php");

     }
      else echo"sessions not set";
   }
   else
     echo "Incorrect Login, please try again";



}
require('header.php');



?>

<form name='loginForm' action='<?php $SCRIPT_NAME?>' method='POST'>

<table>
<tr>
<td> UserName : </td> <td><input type='text' name='name'></td>
</tr>
<tr>
<td> Password : </td> <td><input type='password' name='password'></td>
</tr>
<tr>
<td> </td> <td><input type='submit' name='submit' value='Login'></td>
</td>
</table>

</form>




<?php
require('footer.php');
?>

On successfull login of user , page is redirected to index.php which is using header.php

index.php

Code:

<?php

 require('header.php');
?>

header.php

Code:

<?php
session_start();
 require('config.php');
 $db = mysql_connect($dbhost,$dbuser,$dbpassword);
 mysql_select_db($dbdatabase,$db);
?>

<html>

<head>
<title><?php echo $config_blogname; ?> </title>
<link rel='stylesheet' href='stylesheet.css' tyep='text/css'>
</head>

<body>
<div id='header'>
<h1><?php echo $config_blogname; ?></h1>
</div>
<div id='menu'>
<a href='index.php'>Home</a>
<a href = 'viewcat.php'> Categories </a>
<?php
if(isset($_SESSION['USERNAME']))
{
   echo "<a href='logout.php'> Logout</a>".$_SESSION['USERNAME'];
   echo "<a href='addcat.php'> Add Category </a>";
   echo "<a href='addentry.php'> Add Entry </a>";
}
else
  echo "<a href='loginpage.php'> Login </a> <a href='signup.php'> SignUp </a> ";

?>
</div>
<div id="bar">
<img src= "../shoppingcart/Sai.jpg" width="200px" height="250px" top="200px">
</div>
<div id='main'>

In header.php isset($_SESSION['USERNAME']) is returning false.

have u check in loginpage line 16 $row['username']; is return any thing?

**urfriend202** · Nov 15 '08, 09:48 AM

Yes. It is returning username correctly. In loginpage
isset($_SESSION['USERNAME']) is returning true. But echo $_SESSION['USERNAME'] is not printing anything.

try changing your code in the index.php to:

Code:

<?php
          session_start();
          require('header.php');
?>

I hope this helps!

That shouldn't change anything but give you a notice for starting the session again.

Take lines 17 and 18 out of loginpage.php - this won't be the problem, but you don't need to use them.

I can't see anything wrong with what you posted.

We'll have to see if someone else can spot it.

The solution you have suggested (to add session_start() in index.php) is working in IE but not in mozilla. In mozilla firefox the problem still persists.

try to take out these lines from your login.php:

Code:

session_register('USERNAME');
session_register('SESS_LOGGEDIN');
