Can't use function return value in write context

mosherben

Hi,
I have a file called index.php which includes login.php and functions.php. My idea is that the page will be posting to it's self but I am having trouble getting my login system to work. Here's my code for my 3 files.

functions.php

<?php
$loggedIn=false;

function logIn($username,$password)
{
	$sql="SELECT * FROM $tbl_name WHERE username='$username' and password='$password'";
	$result=mysql_query($sql);

$count=mysql_num_rows($result);

if($count==1)
{
	$loggedIn=true;
}
else
{
	echo "Wrong Username or Password";
}
}
?>

<HTML>
<HEAD>
<TITLE>Login</TITLE>
</HEAD>
</HTML>

<FORM ACTION="index.php" METHOD="POST">Username
<INPUT TYPE="text" name="Username">Password
<INPUT TYPE="password" name="Password">
<INPUT TYPE=SUBMIT VALUE="submit">
</FORM>
</HTML>

Part of the index.php where the error is occuring:

include('functions.php');

if ((isset($_GET('$username'))&&(isset($_GET('$password')))))
{
	logIn($username,$password);
}

Can anyone see what the problem is?

Cheers,

NogDog

Your array syntax for the $_GET elements in incorrect:

include('functions.php');

if (isset($_GET['username']) && isset($_GET['password']))
{
    logIn($username,$password);
}

Note the use of square brackets for the array index, and no "$" for the index names.
