[SOLVED] Var returned by function is empty

[keeps21]

I have a  page which takes a variable from an URL. Eg /index.php?c=Article

 

// Get variables from url
if ( !isset( $_GET['c'] ) ) {
$controller = 'Article'; // Default to article page showing all articles
} else {
echo "c=".$controller = escape_data($_GET['c']) ;
}

 

The variable from the url is escaped using my escape_data() function and assigned to a variable and echoed out.

 

Here is the escape_data() function.

function escape_data($data) {
if (ini_get('magic_quotes_gpc')) {
	$data = stripslashes(trim($data));
}
$escaped_data = mysql_real_escape_string(trim($data));
return $escaped_data;
}

 

The function is in a separate file but is definitely being included.

 

The problem is on my live server the $controller is empty/not set but on my local server it is working as expected.

 

Also the file works as expected if the escape_data function isn't used, though unescaped data isn't desirable

 

Any ideas?

Even the following doesn't work on the live server, but does on the locahost.

$controller = mysql_real_escape_string($_GET['c']);

 

Could this be a php issue?

Ah I believe I've found the problem.

 

The database connection $dbc was not made public in the function that connects to the database.

 

Now that I've madwe $dbc public the function is working as expected.
