Header Problem

Recommended Posts

I am working on a small website using PHP 4x, MySQL 5.0 and Apache 1.2. When I try to login I get some header problems. I am new to PHP and I am learining it. The logincheck.php code is below:

<?php
session_start();
header("Cache-control: private");
require_once($_SERVER['DOCUMENT_ROOT'].'/sports/includes/db_config.php');

$login_name = $_POST['login_name'];
$password = $_POST['password'];
$password = md5($password);
$userIP = isset($REMOTE_HOST) ? $REMOTE_HOST : @gethostbyname($REMOTE_ADDR);
$today = date("Y-m-d h:m:s");
$sql = "SELECT * FROM admin WHERE login_name='$login_name' AND password='$password'";
$query = "UPDATE admin SET last_login = '$today', ip_address = '$userIP' WHERE login_name = '$login_name'";
$result = mysql_query($sql) or die("Unable to execute $sql query: " . mysql_error());
$count = mysql_num_rows($result);
if($count == 1)
{
@mysql_query($query) or die("Unable to execute $query query: " . mysql_error());
$_SESSION['login_name'] = $login_name;
header("Location: ./admin/adminhome.php");
}
else
{
header("Location: relogin.php");
}
?>

I get this error in the browser:

Warning: open(/tmp\sess_612acdf0193058442bb485e14b7d713b, O_RDWR) failed: No such file or directory (2) in c:\apache group\apache\htdocs\sports\logincheck.php on line 2

It can't write your session file.

Check your PHP.ini file and make sure you have read / write access to the folder. All the other errors are because it has already sent the headers (means it has already output something to the screen).

Read item # 4 in our session troubleshooting guide:
[a href=\"http://www.phpfreaks.com/forums/index.php?showtopic=31047&view=findpost&p=157705\" target=\"_blank\"]http://www.phpfreaks.com/forums/index.php?...ndpost&p=157705[/a]

Remember to restart your server after making any changes to the php.ini file so the changes take effect.

If you're new to PHP, please post in the newbie topic area. I'm moving this post there. Thanks.
