[SOLVED] Wierd Error?

[Crew-Portal]

I have never seen this before. I just started making a new login script and about 3 minutes into it I started getting an error:

Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

 

Here is the script

login.php

<?php
session_start();
?>
<form action="go.php" method="post">
  Username: <input type="text" name="username" />
  Password: <input type="password" name="password" />
  <input type="submit" value="Login" class="button">
</form>
<?php
echo $login_s;
?>
<?php if (isset($_POST['destroy'])) { //if login pressed
session_destroy();
} else { //else show form
?>
<form action="" method=post>
<input type=submit name=destroy value=Destroy Session!>
<?php } ?>

 

go.php

<?php
session_start();
$connection = @mysql_connect(localhost, ****, *******) or die("Couldn't connect.");
$db = @mysql_select_db(database, $connection) or die("Couldn't select database.");

$sql="SELECT * FROM user
WHERE username = \"$_POST[username]\" AND password = \"$_POST[password]\"";

$result = @mysql_query($sql,$connection) or print("<b>A fatal MySQL error occured</b>.\n<br />Query: " . $query . "<br />\nError: (" . mysql_errno() . ") " . mysql_error());
$num=mysql_num_rows($result);
while ($row = mysql_fetch_array($result)) {
$active = $row['active'];
$confirm = $row['confirm'];
}
if($num >0) {
if($active == "yes") {
$valid_user = $_POST['username'];
session_register("valid_user");
if (isset($valid_user)){
$login_s = 'You Have Been Sucessfully Logged In!';
}
include("index.php");
}
}
?>

 

Okay I do realize this script is not safe but As I said I started designing it 2 minutes ago so who really cares. The only problem is that I got this error. Could someone help?

You might want to read up on sessions. session_regsister() has long been depricated.

Hu? I didnt change the script and all of a sudden the error just stopped coming up! it may have been an error in the PHP .dlls itself? IDK but its working fine now so sorry for buggin you guys!

 

TOPIC SOLVED!!!

Still, session_register() has long bee depricated and should no longer be used.

Wait the errors back and what do you mean it shouldnt be used? How am I supposed to register variables in PHP5?

How am I supposed to register variables in PHP5

 

session_registaer() was deprictaed long before php5.

 

A simpe example...

 

p1.php

<?php

  session_start();
  $_SESSION['foo'] = 'bar';
  echo '<a href="p2.php">link</a>';

?>

 

p2.php

<?php

  session_start();
  if (isset($_SESSION['foo'])) {
    echo $_SESSION['foo'];
  }

?>

 

No session_register() required.
