Okay i have this problem,i need to do some modifications in the registration page (zip code)it will only recognize us zip codes i need it to recognize uk postcode to heres the code

if (!isNotNull($txtZIP)) {
        $message .= "* Zip cannot be empty! <br>";
    }
	elseif($txtZIP==0 || (strlen($txtZIP)!=5 && $ddlCountry=="US"))
	{	
		 $message .= "* Enter valid Zip code! <br>";

PHP:

if anyone can help it would be very helpful

Thanks

 

You probably need to change this line

elseif($txtZIP==0 || (strlen($txtZIP)!=5 && $ddlCountry=="US"))

it's checking whether zip is 0 or length of zip is not equal to 5 and country is US
if true then it considers it as invalid zip..

 

looks like it should be

if (is_null($txtZIP)) {

Code (markup):

and it's

 elsif 

Code (markup):

note missing the e

 

Thanks i have tried both of the above with no luck,

thanks
