Still sessions

alex57

Hey I get these error messages when trying to start my sessions:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Program Files\xampp\htdocs\Login\home.php:5) in C:\Program Files\xampp\htdocs\Login\home.php on line 6

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Program Files\xampp\htdocs\Login\home.php:5) in C:\Program Files\xampp\htdocs\Login\home.php on line 6

Any ideas would be appreciated thanks.

Here is my code:

<?php

mysql_connect("localhost", "root", "dinosaur") or die(mysql_error());

mysql_select_db("info") or die(mysql_error());

$username = $POST['username'];
$password = $POST['password'];

$result = mysql_query("SELECT * FROM users WHERE username = '$username' && password='$password'");

$row = mysql_fetch_array($result);//the result

if(($row['username'] == $username) && ($row['password'] == $password) && (mysql_numrows($result) == 1))//check username and password
{
//session_start();

//$_SESSION['username'] = $username;
?>
<script language="JavaScript" type="text/javascript">
window.location.replace("home.php");
</script>
<?php
}
elseif (mysql_numrows($result) == 0) {
echo "incorrect login, please retry in 2 seconds ...";
?>
<meta http-equiv="refresh" content="2; URL=login.php">
<?php
}

<?php
session_start();

echo "hey, you are logged in g !!!";
echo "your session ID is : " . session_id();

sorry, resolved that one, was extra spaces before the session_start().

Schoolboy error !!

hey
I always use this

I put session_start as soon as possible in a script where i will use sessions.
because if before session_start happens to be a 'PHP Notice',
there can be an output of html to display and that means a sending of header

and then later in script when
session_start();
comes, you will get this 'Warning headers already sent'

<?php
session_start();
