trouble with session variables
The problem is that I need to declare & use some session variables for logging in

this is the verify password file: just took out the ip's

<?php
session_start();

$connection = mysql_connect("???.???.??.???","root") or die ("Unable to connect to server.");

$db = mysql_select_db("users",$connection) or die ("Unable to find Reciept database.");

$sql = "SELECT password FROM users WHERE username = '$_POST[username]'";

$sql_result = mysql_query($sql, $connection) or die (mysql_error());

$row = mysql_fetch_array($sql_result);
$passcheck = $row["password"];



if ($_POST['password'] != $passcheck)
{
header("Location: http://???.???.??.???/php");
exit();
$_session['logg'] = "no";
}
else
{
header("Location: http://???.???.??.???/php/main.php");
exit();
$_session['logg'] = "yes";
}
?>

and then this is the main.php

<?php
session_start();

if($_session['logg'] = "no")
{
header("Location: http://155.238.93.171/php");
exit();
}
?>
<html>
<head>
<title>ICDL Prog</title>
...


but now the problem is that even if you logg in correctly main still sends you back to the logg in screen, even though $_session['logg'] should be = "yes";

Any help would be appreciated

You need an extra equal sign in your log check. With only the single, you're actually setting $_SESSION['logg'] to 'no' instead of checking it.

I just telling u that u have some miscoding in u'r script.
$connection = mysql_connect("???.???.??.???","root","password")
$sql = "SELECT password FROM users WHERE username = '$_POST[username]'";
It should $_POST['username']
one more thing as per my knowledge
u use relative path in header function.just mention the name of file if both are in same folder.
tried it out

another thing you need to do is set your session variables and callsession_write_close() before calling header()
