php login script

Post by alchemist »

Hallo everyone.
I tried to make login script as it is described here. http://www.phpeasystep.com/phptu/6.html. Tell you the truth, I just copied everything but while trying to log in I get following message:
Warning: session_register() [function.session-register]: Cannot send session cookie - headers already sent by (output started at C:\Program Files\VertrigoServ\www\test\checklogin.php:1) in C:\Program Files\VertrigoServ\www\test\checklogin.php on line 32

Warning: session_register() [function.session-register]: Cannot send session cache limiter - headers already sent (output started at C:\Program Files\VertrigoServ\www\test\checklogin.php:1) in C:\Program Files\VertrigoServ\www\test\checklogin.php on line 32

Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\VertrigoServ\www\test\checklogin.php:1) in C:\Program Files\VertrigoServ\www\test\checklogin.php on line 34
Any ideas? :banghead:

here is the code for checklogin.php

Code: Select all

<?php
ob_start();
$host="localhost"; // Host name 
$username="root"; // Mysql username 
$password="vertrigo"; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="members"; // Table name 
 
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
 
// Define $myusername and $mypassword 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword']; 
 
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
 
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
 
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
 
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword"); 
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
 
ob_end_flush();
?>
I think there is no any output or any other thing that can possibly lead to these errors.

If your editing in a Unicode character encoding, such as UTF-8, check your editor isn't saving a BOM.
