Mysql user/sessions

[lewisstevens1]

Hello i am using mysql sessions to bring back data recalled from a database, the thing is i had to use a premade login script and dont know how to get this working, i can get it working by like selecting id 1, though i wanted to have it so it selects the data by the person logged in, this is some of the code i have.

 

i am only posting the usefull parts though i will attach the files used here as an attachment, if theres any more you want just ask and i can send the whole entire script. I know some divs may not be closed but thats because i shortened it.

 

 

index.php

<?php 
session_start();

if (!isset($_SESSION['user']))
{
header("Location: login.php");
}
?> 

<?php
require_once 'connect.php';

$sql="SELECT * FROM $tbl_name ORDER BY id DESC";
// OREDER BY id DESC is order result by descending 
$result=mysql_query($sql);
?>

<?php
while($rows=mysql_fetch_array($result)){ // Start looping table row 
?>

<?php if (isset($_SESSION['user'])) { ?>
<p>Logged as <?php echo $_SESSION['user']; ?> | <a href="settings.php">Settings</a> 
| <a href="logout.php">Logout</a> </p>
<?php } ?>

Well, you'll need to pull back some from the session (cookie, session_id, whatever).

[lewisstevens1]

:S still dont really understand... how will i get it so it echos the users level from the database of that user.

You have to figure out who is logged in somehow -- I assume you're storing that somehwere.
