Functions are driving me crazy....

[Jason Pruim <japruim@xxxxxxxxxx>]

Hi everyone :)

So partly to get an answer, and partly to boost my post rankings for  
the week I have a question.

I am attempting to write an authentication function which would query  
a database, check the username/password and return true if it matches.  
If it doesn't match, then it shouldn't return anything and they are  
denied access.

Here is the code for the function:

<?PHP
	
	function authentication(){
		if($user && $pass) { // Keep in mind, PASSWORD has meaning in MySQL
			// Do your string sanitizing here
			// (e.g. - $user = mysql_real_escape_string($_POST['user']);)
			$loginQuery = "SELECT * FROM login WHERE user='".$user."' AND  
Userpass='".$pass."' LIMIT 0,1;";
			$loginResult = mysql_query($loginQuery) or die("Wrong data supplied  
or database error"  .mysql_error());
			while($row1 = mysql_fetch_array($loginResult)) {
				$_SESSION['user'] = $row1['User'];
				$_SESSION['loggedin'] = "YES";
				$authenticated = "true";
			}
		}
	}return $authenticated;
?>

and here is the code that I am using to call it:

$authenticated = authentication($user, $pass);

but when ever I try and run it I get the following errors in my log  
file, and the page doesn't load the info in the database.

Help me please!



My error log shows this:

[Fri Jan 25 14:55:14 2008] [error] PHP Notice:  Undefined variable:
