Smarty

[ricklach]

I have created a function to check a postal code. the file is called smarty_validate_criteria_isPostalCode.php and here is the code;

function smarty_validate_criteria_isPostalCode($value, $empty, &$params, &$formvars) {

$value = preg_replace("/[\s|-]/", "", $value);
$length = strlen ($value);
//echo "length = " . $length;
if($length == 0) return $empty;

if ($length <> 6) {
return FALSE;
} else {
return preg_match ("/([A-z][0-9]){3}/", $value);
}
}

I then put this code into the Plugins directory. However, when I try to use it here is what I get:

Notice: SmartyValidate: [is_valid] criteria function 'isPostalCode' was not found. in c:\php\smarty\libs\SmartyValidate.class.php on line 387

Which I believe means it cant find the code which is in the c:\php\smarty\libs\plugins directory. Any idea what the problem is?
