Superseded PHP Session Side-Effect existed until 4.2.3

Hello,

I have tried changing all my login scripts from the old session_registered and $username=$_SESSION[‘Username’] but for some reason the new method of code doesn’t work either and now thing will work, please help as i am lost ?

Check LOGIN Page

[code=php]<?
session_start();
session_destroy();
?>
<?php

// username and password sent from signup form
$Username=$_POST[‘PostUsername’];
$Password=$_POST[‘PostPassword’];

$sql=”SELECT * FROM $tbl_name WHERE username=’$Username’ and password=’$Password'”;
$result=mysql_query($sql);
$count=mysql_num_rows($result);

if($count==1){

// Register $Username, $Password and redirect to file “logged_h.php”
$_SESSION[‘Username’] = $Username;
$_SESSION[‘Password’] = $Password;
header(“location:logged_in.php”);
}
else {
session_destroy();
header(“location:login_failure.php”);
}
?>[/code]

Here is my Logged in code to check to see if the user is registered.

[code=php]<?php
session_start();

if(isset($_SESSION[‘Username’])){

$sql=”SELECT * FROM $tbl_name WHERE username=’$Username’ and password=’$Password’ LIMIT 1″;
$result=mysql_query($sql) or die(“SQL Error: $sql<br>” . mysql_error());
$rows=mysql_fetch_array($result);
$usernamematch=$rows[‘username’];
if($usernamematch==$Username){
$logincheck=”pass”;
}
else{
$checkuser=”failed”;
session_start();
session_destroy();
}
}
else{
$checkuser=”failed”;
session_start();
session_destroy();
}
?>[/code]
