I feel bad about asking a question like this, but I've spent quite a bit of
time trying to track down what should be a simple answer and, no luck.
Anyway...
I'm trying to create a simple function that will match two form fields
against each other, e.g. "Email" equals "Repeat Email". The following
function seems to work, however, I'm a little uncomfortable because I don't
understand it. Specifically, I don't understand why returning $str1 by
itself (or $str2 by itself) makes it work.
---------------------------------------------
/* checks two fields against each other to make sure they match and if they
don't match it throws an error message into the $err_text array */
function CheckMatch($str1, $str2, $name)
{
global $err_text;
$match = ($str1 == $str2);
if ($match != true)
{
$err_text[] = "$name must match.";
}
return $str1;
}
---------------------------------------------
Any help is appreciated! Thanks!
Jeff
