Validating a country / state form input

horseatingweeds · July 30, 2007

I'm having trouble validating a state and country input. I didn't write it so I'm confused about why my code isn't working with it.

This is the form part:

<legend><span>*</span> Location</legend>

</fieldset>

And this is the JavaScript that builds it:

// If you have PHP you can set the post values like this
//var postState = '<?= $_POST["state"] ?>';

//var postCountry = '<?= $_POST["country"] ?>';

var postState = '';

var postCountry = '';

// State table

//

// To edit the list, just delete a line or add a line. Order is important.

// The order displayed here is the order it appears on the drop down.

//

var state = '\

And here is the code that is acting funny:

$country = $_POST['country'];

$state = $_POST['state'];

if ($country == ('CA' || 'US' || 'AU' || 'BR' || 'NL' || 'UK' || 'EI'))

{

if ($country == ('NL' || 'US' || 'UK'))

{

$response = 'Plesae enter a state for your location in the ' . $country;

}

else

{

$response = 'Plesae enter a state for your location in ' . $country;

}

Regardless of the input, the function returns the else response.

if ($country == ('CA' || 'US' || 'AU' || 'BR' || 'NL' || 'UK' || 'EI'))

You have to compare country separately to each of these values. You cannot use the OR operator like that. So,

if ($country=="CA" || $country=="US")

and so on with the OR operator
