add word NONE to zip in validation

[kabucek]

hi @LL,

we are using simple code for validation in zip, but now we want to be able to type the word
"NONE" also.
How this code can be modified to do that?

case 'zip':
if ($inString=='') { appendError("Required Field"); }
else {
$length=strlen($inString);
switch($length)
{
default:
appendError("Must be 5 digit zip '00000', or zip+4 '00000-0000' or 'NONE'");
break;

case '5':
$pattern="^[[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]]$";
$emailTest=ereg($pattern, $inString);
if (!$emailTest) { appendError("Only numbers allowed in zip"); }
break;
case '7':
$pattern="^[[:digit:]][[:digit:]][[:digit:]][[:space:]][[:digit:]][[:digit:]][[:digit:]]$";
$emailTest=ereg($pattern, $inString);
if (!$emailTest) { appendError("Canadian postal codes must be three digits, one space, three digits"); }
break;
case '10':
$pattern="^[[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]]-[[:digit:]][[:digit:]][[:digit:]][[:digit:]]$";
$emailTest=ereg($pattern, $inString);
if (!$emailTest) { appendError("Not a valid Zip+4 format"); }
break;




Thanks

Something like this should work:

case 'zip':
    if ($inString=='') {
        appendError("Required Field");
    } elseif($inString != 'NONE') {
        $length=strlen($inString);
        switch($length)
        {
            default:
                appendError("Must be 5 digit zip '00000', or zip+4 '00000-0000' or 'NONE'");
            break;
            case '5':
                $pattern="^[[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]]$";
                $emailTest=ereg($pattern, $inString);
                if (!$emailTest) { appendError("Only numbers allowed in zip"); }
                break;
            case '7':
                $pattern="^[[:digit:]][[:digit:]][[:digit:]][[:space:]][[:digit:]][[:digit:]][[:digit:]]$";
                $emailTest=ereg($pattern, $inString);
                if (!$emailTest) { appendError("Canadian postal codes must be three digits, one space, three digits"); }
                break;
            case '10':
                $pattern="^[[:digit:]][[:digit:]][[:digit:]][[:digit:]][[:digit:]]-[[:digit:]][[:digit:]][[:digit:]][[:digit:]]$";
                $emailTest=ereg($pattern, $inString);
                if (!$emailTest) { appendError("Not a valid Zip+4 format"); }
                break;
        }
    }

SJH already replied it. Maybe you may also accept 'none', 'None' ...

(strtolower($inString)!='none')

[kabucek]

SJH,
that worked perfectly!!
Thanks!!

glenngould,
Can we modify it so it will take lower & upper case?
for ex. 'none' or 'NONE' ?

THANKS!

[glenngould]

The one I wrote does that already (also for 'nOne' 'None' etc.).

Canadian postal codes are not all digits, ie: T1B 4A5. You would need to change your pattern and error message for case 7.

$pattern="^[[:alpha:]][[:digit:]][[:alpha:]][[:space:]][[:digit:]][[:alpha:]][[:digit:]]$";
