On the checklogin.php page change

 

$_SESSION['is_valid'] = true;

 

to

 

$_SESSION['is_valid'] = "true";

 

and try that.

 

Ok so:

 

session_start();
echo $_SESSION['is_valid'];
exit();

 

to

 

session_start();
echo $_SESSION['is_valid'] = "true";
exit();

If you want us to program for you please "Don't ask someone to write or re-write a script for you, unless you are posting a message to the Freelancing Forum. The forums are not the place to request XYZ script. This is a community of people learning PHP, and not a script location service. Try searching SourceForge, PHP Classes, HotScripts, or Google."

 

I'll stop posting in this thread now it's just really annoying to see

no, on your check login page, you set $_SESSION['is_valid'] = true; if the user is logged in.

 

right here

 

// Register $myusername, $mypassword and redirect to file "index.php"
$_SESSION['username'] = $myusername;
$_SESSION['is_valid'] = true;
session_register("myusername");
session_register("mypassword");

 

change it there

This is what I have for now.

 

If you can be nice enough to add in the codes in the correct spots would be great.

<?php
session_start();
$_SESSION['is_valid'] = "true";

$username = "bucketho_****"; // <-- Mysql username MAKE SURE THIS IS SET!
$password = "*****"; // <-- Mysql password MAKE SURE THIS IS SET!
$db_name = "bucketho_*****"; // <-- Database name CHANGE THIS TOO!
$tbl_name = "members"; // Table name
// Connect to server and select databse.
mysql_connect($host, $username, $password)or die("cannot connect");
mysql_select_db($db_name)or die("cannot select DB");

if ($_GET['change_pass'] == true && $_SESSION['is_valid'] == true){
$new_pass1 = mysql_real_escape_string($_POST['pass1']);

$old_pass = mysql_real_escape_string($_POST['old_pass']);
$username = $_SESSION['username'];
$sql = "SELECT COUNT(*) AS `total_found` FROM `members` WHERE `username`='$username' AND `password`='$old_pass' LIMIT 1;";
$result = mysql_query($sql);
$row = mysql_fetch_assoc($result);
$total_found = $row['total_found'];
if (($total_found == 1) && ($new_pass1 == $new_pass2)){
	$sql = "UPDATE `members` SET `password`='$new_pass1' WHERE `username`='$username';";
	mysql_query($sql);
	header("location:./");
	exit();
}
else{
	print "Error processing Password change. Please try again";
}
}
