getting user details from a database

[buddysal]

how do i get info about a user from a databse when its laid out like this...

Index.php > login.php > members.php

the login is on index.php login.php is only a processing script and it redirects to members. php

i need to get the username and the other database rows listed on members.php but i dunno how to do that, or how to carry the username on members.php from login.php

you need sessions, or a cookie

im trying to do something with sessions but its not working....

this is on my login script

if (!mysql_num_rows($query) < 1) { 
session_start();
$_SESSION['username'];
header("Location: http://www.ragz-to-richez.com/members.php");
}else{ 
echo "Oops username or password was wrong! retry again or <a href=http://www.ragz-to-richez.com/signup.php>Click Here</a> to get a free account"; 
} 

this is on my members.php

if (isset($_SESSION['username']) == false) {
header ("Location: http://www.ragz-to-richez.com");
} else {

well i dont know quite what the line:

$_SESSION['username'];

is supposed to do, but it doesnt do anything.

From the manual:

Note: Please note when working with sessions that a record of a session is not created until a variable has been registered using the session_register() function or by adding a new key to the $_SESSION superglobal array. This holds true regardless of if a session has been started using the session_start() function.

so i think you're trying to use session_register(), but not if you see what i mean.
