Dear all,

I've tried to create a custom validation rule for a dutch zipcode. I've succeeded in getting a rule in the validation.php and I'm able to select it.

However: I think I've got the rule itself wrong:
function nlzipcode($value)		// toegevoegd door M.R. Visser tbv NL-postcode validatie
	{
	return preg_match("/^([0-9]{4})([A-Z]{2})?$/i",$value);
	}

A dutch zipcode is in this format: 9999AA (e.g.: my zipcode is 3723LD).

What did I do wrong?

Regards,
Marco Visser
