RSForm!Pro - Unique registration number

Unique registration number

In this article we will describe how to ensure that the registry number is correct. For instance, if you enter a registration number, it must only allow a number which is on a predefined list. It will not allow a number which is not known. These codes will not be visible to the public.

In order to achieve this a new validation rule will have to be added to RSForm! Pro. Just edit the file /components/com_rsform/helpers/validation.php and add the new validation function here:

 
function registrationCode($param,$extra=null)
{
$validCodes = array('AAAA','BBBB','CCCC','DDDD');
$bul = true;
foreach($validCodes as $validCode)
if(strtolower($validCode) == strtolower($param))
{
$bul = true;
break;
}
else
$bul = false;
return $bul;
}
 

Now a new validation rule will be selectable for your fields. You will just have to change the codes 'AAAA', 'BBBB', 'CCCC' and 'DDDD' with the ones of your choice.
