Session Cookie/Cache limiter/Headers Error ?

Recommended Posts

hi, im gettin the following error, when i put the code with some html.


Warning: session_register(): Cannot send session cookie - headers already sent by (output started at c:\project\htdocs\checklogin.php:1) in c:\project\htdocs\checklogin.php on line 34

Warning: session_register(): Cannot send session cache limiter - headers already sent (output started at c:\project\htdocs\checklogin.php:1) in c:\project\htdocs\checklogin.php on line 34

Warning: Cannot modify header information - headers already sent by (output started at c:\project\htdocs\checklogin.php:1) in c:\project\htdocs\checklogin.php on line 35

my php code :

<?php
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="dv8_database"; // 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");

$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 and redirect to file "login_success.php"
session_register("myusername");
header("location:login_successful.php");
}
else {
echo "Wrong Username or Password";
}
?>


its a simple login form and happens when the username and password is correct.

thanks
