PHP 5.2 sessions

Post by **Helx** » Fri Jun 29, 2012 10:35 am

Wow, PHP 5.2 is really annoying XD

Right, so I have this code:

<?php
	  session_start();
      if(isset($_SESSION['user'])) {
		  $session_username = $_SESSION['user'];
		  ?>
      <img src="<?php echo "http://website.net/render.minecraft.face.php/?player=" . $session_username ?>" height="20" width="20" /> <font color="#666666" style="padding-left:6px"><?php echo $_SESSION['username']; ?></font> // EDIT: lol, I put in the actual website
      <?php
	  }else{
	  ?>
      <font color="#666666"><a href="/login">Login</a></font>
      <?php } ?>

And it will only show the }else{ part EDIT: (after logging in). *irked*

This is the login script:

<?php
	
	include('core/DB_connect.php');
	$user=$_POST['user']; 
	$password=$_POST['password'];
	$user = stripslashes($user);
	$password = stripslashes($password);
	$user = mysql_real_escape_string($user);
	$password = mysql_real_escape_string($password);
	$enc=md5($password);
	$sql="SELECT * FROM $tbl_name WHERE username='$user' and password='$enc'";
	$result=mysql_query($sql);
	$count=mysql_num_rows($result);
	if(isset($_POST['user'])){
		if($count==1){
			session_start();
			$_SESSION['user'] = $_POST['user'];
			header("Location: ../");
		}else{
			$false_enc = '<b><font color="#CC0000">Incorrect details</font></b>';
			$enc_type = 'text-input-wrong';
		}
	}else{
		$false_enc = 'Need help? Contact the <a href="/contact/admin/">Admin</a>';
		$enc_type = 'text-input';
	}
?>

And the logout script (just in case)

<?php
session_start();
unset($_SESSION['user']); // Its the only thing set, so I'm not going to unset the pass.
header('Location: http://website.net/'); // EDIT: lol, I put in the actual website
?>

I would really appreciate any help, I'm stumped :/

Hmm, well there is no point in defining this variable

$session_username = $_SESSION['user'];

you may as well just use the $_SESSION['user'] one directly.

But if you are always getting the else part that must mean that isset() is always returning false so you could try adding a

print_r($_SESSION);

above that to see what is actually in the session.

print_r($_SESSION); returns "Array ( )"

I'm guessing that means its got something to do with validation?

Maybe the session is never starting on the login page but it's being hidden from you because of the redirect ?

Try commenting out the header("Location: ../"); line and see if an error appears when you log in.

Still returning the same thing sadly...

Is there anything that needs to be explicitly defined for $_SESSION to work?
Something like the older versions, where session_start() was required? (I do have session_start() in the code.. Might that be the reason?)

EDIT:

Ah, ok. I think it may be something to do with PHP itself...

Yeah all you need is the session_start() and a browser that will accept the cookie that it sends.

No, that is from 2006

Do you definitely have error_reporting turned on ?

Everything looks like it should work really.

Thats the thing getting me stuck, I see no problems. Oh, and I turned error_reporting(); to "E_ALL"... Is that right?
When I do that, the Array ( ) still stands..

Okay, I think I'll paste the (almost) entire website here I guess...

Index.php (home page, auth not REQUIRED)

<?php
include('core/init.inc.php'); // This is for the template system... Don't worry about it.

And /login/logout.php

<?php
session_start();

unset($_SESSION['user']);
unset($_SESSION['passwd']);

header('Location: ../');
?>

This really is getting on my nerves now, PHP never used to be this difficult

Are you sure I don't have to enable any PHP modules?

Well, if it won't work, then thanks for your help anyway. I may try self-defining cookies or something

Post by **jacek** » Sun Jul 01, 2012 12:15 pm

Well the session_start() has to come before any output from the page, but that would normally give you at error. It should really be in your init.inc.php file and nowhere else

If that is the problem then you need to make sure you have display_errors set to On as well as the error_reporting setting.

Post by **Helx** » Mon Jul 02, 2012 7:16 am

Ok

I fixed it!
I'm so happy now, but in case anyone else is having this problem I'll explain how I fixed it.

The variables for the sessions need to be defined in the same if() block. Like this:

if(isset($_POST['user'])){
		if($count==1){
			$duf67f = $_POST['user']; //Set the variable
			
			$_SESSION['log_usr'] = $duf67f; //Define the sessions

			echo "Logged in! : D";
		}else{
			echo "Incorrect credentials.";
		}

Hope it helps.

Thanks for your help jacek

That's odd ! But good that you fixed it
