clean function - getting error

[runnerpaul]

Hi,

 

I am creating a website but am having trouble with the following:

 

I have an include file(db.inc) which contains the following:

 

function clean($input, $maxlength)

{

$input = substr($input, 0, $maxlength);

$input = EscapeShellCmd($input);

return ($input);

}

The file I am having the problem with is my view.php file. I get the following error:

 

Notice: Undefined variable: file in C:\wamp\www\fermpix\view.php on line 4

 

Line 4 contains the following:

$file = clean($file, 4);

 

My view.php does have the line:

include 'db.inc';

 

 

Does anybody have any idea what the issue might be?

 

Cheers

Paul

Where is $file defined?
