My Login Script

[Inigoesdr]

updates.php should look something like this to prevent the undefined index error after login:

PHP Code:

<?php
session_start();
include 'config.php';

if(isset($_POST['user']) && isset($_POST['pass']))
{
    $user = mysql_real_escape_string($_POST['user']);
    $pass = mysql_real_escape_string($_POST['pass']); 
    $stat = mysql_fetch_array(mysql_query("select * from members where user='$user' and pass='$pass'"));

    $_SESSION['stat'] = $stat;

    print "Welcome {$stat['user']}";
}
else if(isset($_SESSION['stat']['user']))
{
    print "Welcome {$_SESSION['stat']['user']}";
}

It been a while since I checked this post as ive been very busy .Ive just made the relevant changes to updates.php and its now just giving me a blank page. I really want to get this sorted

Obviously the session still isnt carrying over. Its frustrating because I want to continue with this site im just well and truly stuck here.

How do you know the session isn't being carried over? - Did you not read my comment previously about you not even using the $_SESSION array? - That is where you store things. In your next script you then call session_start() and the $_SESSION array then contains all the keys and values you used previously in your last script.

I've not seen you use $_SESSION anywhere so how can you claim it's not working? - Anything you want made available to the next script must be put into the session array like this:

Script one

PHP Code:

session_start();
$_SESSION['text'] = 'Hello'; 


Script two

PHP Code:

session_start();
print $_SESSION['text']; 


As for your blank page, if you're on wamp then you'll have an apache error log somewhere which will list the error with the page.

Let me see if I understand what you mean. In the past I would have just put the following in my header file.

$stat = mysql_fetch_array(mysql_query("select * from members where user='$user' and pass='$pass'"));

The session would of kept that alive and then when I wanted to show someones user name I would of just put $stat[user]. But now I have to use session variables. Is that correct?

No it wouldn't. $stat would be forgotten as soon as the script ended.

To use a session, anything you want remembered between scripts must be put into the $_SESSION array. I've made this clear more than once to you yet you seem to do anything but accept it.

No it's not correct. You've ALWAYS had to use session variables it's just that you have not been doing so. If you go back and read my previous replies you will see I have been telling you this multiple times.

Normal variables that you use (eg $User or $stat) were never remembered by sessions. They were available in other files that you might include() or require() but not between scripts on different urls and http calls.

Anything you want remembered between two scripts that are at different urls must go into the $_SESSION array. I've given you a basic code sample above so please use it! It isn't hard, just a call to session_start() in your script and then use the $_SESSION array just like any other array. It's really easy to do
