[SOLVED] global session?

[rhale]

for some reason my session variables dont stay when i use require once on login_success.php and i get these errors. everything works properly when i use them on the checklogin.php but when i try to use them on other pages they dont.

 

 

Notice: Undefined index: myusername in C:\wamp\www\login\checklogin.php on line 13

 

Notice: Undefined index: mypassword in C:\wamp\www\login\checklogin.php on line 14

Wrong Username or Password

Notice: Undefined variable: _SESSION in C:\wamp\www\login\login_success.php on line 5

 

checklogin.php

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

// username and password sent from form 
$myusername=$_POST['myusername']; 
$mypassword=$_POST['mypassword']; 


$sql="SELECT username and password FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
$accesslevels = mysql_query("SELECT accesslevel FROM $tbl_name WHERE username='$myusername' and password ='$mypassword'");
$accesslevel = mysql_fetch_assoc($accesslevels); 


// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

//register user and accesslevel
if($count==1 and $accesslevel['accesslevel']=='1'){
session_start(); 
$_SESSION['user'] = $myusername;
$_SESSION['accesslevel'] = $accesslevel['accesslevel'];
header("location:login_success.php");
}
elseif($count==1 and $accesslevel['accesslevel']=='2'){
session_start(); 
$_SESSION['user'] = $myusername;
print $_SESSION['user'];
echo "welcome manager"; 
}
elseif($count==1 and $accesslevel['accesslevel']=='3'){
session_start(); 
$_SESSION['user'] = $myusername;
print $_SESSION['user'];
echo "welcome admin"; 
}
else {
echo "Wrong Username or Password";
}
?>

 

 

login_success.php

<?php
// Check if session is registered
require_once 'checklogin.php';
print $_SESSION['user'];
?>

You're not placing

session_start();

 

At the top of your pages. session_start() allows session variables to continue on from page to page.

The session_start() will be the first line i think.
