Help needed :) If Error then

[WhOOt]

Hey out there 🙂
I don't know.. this might should have been in the newbie section...
Here it comes 🙂
I've made a Login / Register script.

I have an error;

Notice: Undefined variable: _SESSION in c:\xx\usersfiles.php on line 2

I belive my problem is that the variable is not defined, when user is not logged in.

I guess it'd be easier, if you could see my scripts... 🙂
Please respond to this message, if you want the scripts, to help me 😃

EDIT::
The thing I belive would help is like the command in VB,
If Error then...
If not logged in then...
know what I'm saying? 🙂

umm... PHP varabiables take on the form of
$[a-zA-Z\x7f-\xff][a-zA-Z0-9\x7f-\xff]*

So "SESSION" is not a variable, but a string. "$SESSION" would be a variable.

Try changing SESSION to $SESSION in your code.

Read up on [man]variables[/man] in the PHP manual as well.

looks like you are not calling [man]session_start[/man]

usersfiles.php should be:

<?php
session_start();
echo $_SESSION['username']."'s Files";
?>

loginner.php should start like this:

<?php
if ($_POST['username']) 
{

session_start();
		echo '<style type="text/css">
<!--
.style1 {font-size: 14px}
-->
</style>
 <span class="style1">';
// set your infomation.
$dbhost='localhost';
$dbusername='root';
$dbuserpass='';
$dbname='users';



// connect to the mysql database server.
mysql_connect ($dbhost, $dbusername, $dbuserpass);
mysql_select_db($dbname) or die('Cannot select database');

//did they supply a password and username
$username=$_POST['username'];
$password=$_POST['password'];
if ($password==NULL) {
	echo "A password was not supplied";
}else{
	$query = mysql_query("SELECT username,password FROM users WHERE username = '$username'") or die(mysql_error());
	$data = mysql_fetch_array($query);
	if($data['password'] != $password) {
		echo "The supplied login is incorrect";
	}else{
		$query = mysql_query("SELECT username,password FROM users WHERE username = '$username'") or die(mysql_error());
		$row = mysql_fetch_array($query);
		$_SESSION["s_username"] = $row['username'];
	}
}
echo "Logged in as ".$_SESSION['s_username']." <a href='logout.php'>LogOut</a>.";
echo '</span>';
}
else
{
?>

<h1 class="style1">Login</h1>
      <form action='index.php' method='POST' class="style1">
        <table style='border:1px solid #000000;'>
          <tr>
            <td align='right'> Username:
                <input type='text' size='15' maxlength='25' name='username'>
            </td>
          </tr>
          <tr>
            <td align='right'> Password:
                <input type='password' size='15' maxlength='25' name='password'>
            </td>
          </tr>
          <tr>
            <td align='center'>
              <input name="submit" type="submit" value="Login">
            </td>
          </tr>
          <tr>
            <td align='center'> <a href='register.php'>Register Here</a> </td>
          </tr>
        </table>
        <p>
		<?

	?>
	&nbsp;</p>
  </form>
<?
}
?>

Devinemke was right... you were missing the session_start()....

Read up in the manual on [man]session_start[/man]. It has to be the first line, and nothing can be sent to the browser first (inlcuding HTML). Otherwise, you get that error.
