Is there a shortcut way of letting your form proceesor know that if ANY fields besides the email contain html or script tags that it should die?

Here's the code I have (from John-Marc) to keep it out of the comments text area:

PHP Code:
if (ereg('[http\\:\\/\\/]*[www\\.]*[A-Za-z0-9_-]+\\.[A-Za-z0-9]+', $_POST['comments'])) 
{
header("Location: error.php");
exit;
}
