keep the state/province "not emtpy" validation checking on or off?

[blackhorse]

For USA or Canada or many other countries, we have javascript and php script to check to see if the customer fill in the state/province field yet in their order form.

But once a while, we will run into some cases that the countries(or areas) the customers from don't have state or province level information.

So we turn off the "not empty" validation checking on the state/province field in the order form. But then we miss the validation checking for most countries which has state or province.

How do you handle it? keep the state/province "not emtpy" validation checking on or off?

The same question goes with the zip code, some countries don't have the zip code, so do we have the zip code "not empty" validation checking on or off?

Thanks!

Simply do a two-part condtion: if the country is one of a set of countries for which you want to know the state/province, then check to see if it has been provided. E.g.:

if(in_array($country, array('USA', 'Canada') and empty($state))
{
   // raise error for empty state field
}
