Hi,

I would like to add a required field for a coupon code input that is needed to submit. How do I do this?

Thank you for your help.

Diana

Hi Diana,

I would use Custom Serverside validation to check that the coupon code is valid.

Hi Bob,

I used this that I found in another post but if I put in something other than SUG2014 it still submits. Is there something I am missing?

Is there a way to have 3 or 4 coupon codes in the statement?

<?php
$promo_code = JRequest::getString('promo_code', '', 'post');
if ( $promo_code && $promo_code != 'SUG2014' ) {
      return "Sorry, that is an invalid promo code";
}
?>

Hi Diana,

I think that the V$ you have here is probably CFv4 . . . if it is then please see this FAQ

Bob

Yes, CFv4.........sorry typo

I added the code as in the Faqs but it doesn't work just throws the error message no matter what I put in the field.

HI Diana,

Exactly what code are you testing? The code in your previous post isn’t quite the same as the example in the FAQ.

Bob

I tried the code in the faqs post. I must need to do something else maybe in the field setting, but the faqs didn't address that. Here is what I used.

<?php
$ok_values = array(
  'sug2014', 
  'specialsug',
  'sugfree'
);
if ( !in_array($form->data['data'], $ok_values) ) {
  $form->validation_errors['data'] = "Sorry your promo code is incorrect. Please refer to your StandUpGirl Promo letter for the correct promo code";
  return false;
}
?>

Hi Diana,

That looks OK except that you have replaced 'promo_code' with 'data' What is the name of the input you are using for the promo code?

Bob

That was it Bob..................thank you! I just wasn't sure what to change in the code other than the promo codes themselves.

Works perfectly!

Cheers!
