Help with business map - validation

[elisa.deko]

Hello,

regarding to your question, I would suggest you to create a Custom Validation.
I'm writing here an example for you (pls put the right field names before testing )

PHP Code:

<?php

function checkCreditCard($fieldname, $fieldvalue, $params, $entity)
 {
 $current_record = $entity['recordid'];
 $type = $entity['typeofpayment'];
 $pno = $entity['paymentsno'];
 $pattern = '^(?:0[1-9]|10)$';
 if ($type == "Credit Card" && preg_match($pattern, $pno) && !empty($pno))
 {
 return true;
 }
  else
 {
 return false;
 }
 }

?>

Then in your Validations Map you should add the following validation:
...
<field>
           <fieldname>paymentsno</fieldname>
           <validations>
               <validation>
                   <rule>custom</rule>
                   <restrictions>
                       <restriction>include/validation/checkCreditCard.php</restriction>
                   </restrictions>
               </validation>
           </validations>
       </field>
...

I hope this helps
