Reg Expression: Canadian Zip Code

[timbr8ks]

I need a code that says:

If the country is Canada and the zip code is not [letter][number][letter][space][number][letter][number] (e.g., G3H 6A3), then the zip code is wrong.

Here's what I have:

$pattern_canada = "/^[A-Z]\d[A-Z] ?\d[A-Z]\d$";
if (@$_POST['Country'] == "CANADA" && !ereg($pattern_canada, $_POST['Zip'])) {
	$message[] = "<li>You must enter a valid Zip Code</li>";

... but it's not working. I've also tried:

$pattern_canada = "^[A-Z]\d[A-Z] ?\d[A-Z]\d$";
$pattern_canada = "^{[A-Z][0-9][A-Z][]?[0-9][A-Z][0-9]$";}
$pattern_canada = "^{[A-Z][0-9][A-Z]\s?[0-9][A-Z][0-9]$";}

... and just about every combination of these options as I could think of. But it's still telling me that G3H 6A3 is an invalid Canadian Zip Code.

Can anyone tell me what I'm doing wrong here?

Thanks.

$pattern_canada = "/([A-Z][0-9]A-Z*[0-9][A-Z][0-9])/i"

Don't put /i if you only expect upper case letters.

$pattern_canada = "^{[A-Za-z][0-9][A-Za-z]} ?[0-9][A-Za-z][0-9]$";

Or alternatively, use the one the poster above used, but with preg_match instead (it doesn't work with ereg)

With a slight variation, it worked. I used:

$pattern_canada = "^[A-Za-z][0-9][A-Za-z] ?[0-9][A-Za-z][0-9]^";

Note the ^ instead of $ at the end. I also used preg_match.

Thanks to you both.
