logging in help

Lamez · August 26, 2007

I have been trying to fix this annoying script error for hours and nothing is working.

This has been working until now.

I log in, and it recognizes my username and password and allows me to login, but when I get to the members page it says I am not logged in. The only page I modified is the members page.

Here is my member's page script

echo "<u>Welcome</u> <b>$username</b>";
?>
</center></font></div>


<?php
$getlink = $_GET["process"];

if ($getlink == "members_list") {

USERNAME: test

PASSWORD: test

Uh was the cookie ever set?

Lamez · August 26, 2007

I believe so

I think this is what is giving me trouble

<?php //makes sure the user is logged in
$username = $_COOKIE['loggedin'];
if (!isset($_COOKIE['loggedin'])) die("You are not logged in, <a href=../../login.php>click here</a> to login.");
echo "<u>Welcome</u> <b>$username</b>";
?>

Ken2k7 · August 26, 2007

Right, but I can't tell from that code whether the cookie was set.

Lamez · August 26, 2007

I am using sessions from what I understand, is that the same thing as a cookie?

Sorry I am a PHP noob still learning.

Ken2k7 · August 26, 2007

No. $_SESSION will only keep the information as long as the user stays on the site. Once the user exits the page, the $_SESSION is deleted. $_COOKIE is different. You can set a cookie to expire after some specified time or until the user closes the browser.

Try if (!isset($_SESSION['loggedin'])) or whatever you named it. Though I would not use loggedin as the name for a session because you don't know who the person is.

Lamez · August 26, 2007

My Database is online.

I am not sure what the heck is going on. Do you think it could be my login script? Man I am so lost.

Ken2k7 · August 26, 2007

Post in your login script.

<?php

$match = "select id from $table where username = '".$_POST['username']."' 
and password = '".$_POST['password']."'"; 

?>

Try replacing the one you have for match with that one. that. Also for num_rows, it's not going to be < 0, so just say == 0.

Lamez · August 26, 2007

nope, man I am tired of this, I am going to go to sleep for a while, thanks though

Ken2k7 · August 26, 2007

It says $_POST['username']. Where's the form?

Lamez · August 26, 2007

that script was my script to log you in from the users input, or the form action

here is the form action url http://lamezz.com/_bin_/login.php

here is the form http://lamezz.com/login.php

here is the login form code

Hmmm in your login script, it says something like:

$sql = "select id from $table...";

Is $table defined?

Lamez · August 26, 2007

yea in my config.php

its ac_users or in my words account users

Ken2k7 · August 26, 2007

Okay try verifying the cookies by using echo $_COOKIE["loggedin"];

Lamez · August 26, 2007

would I put that in my members page?
