difficulty with duplicate field

[germanoalves]

Hello I have a question:

I have an order registration form with the following structure:

- name
- email

-product
-amount

The fields 'product' and 'quantity' are in a repeating group.

I would like to know if I can limit repetitions of selected items, for example, in the 'product' field, so that if a user tries to add an item already inserted more than once, an error message or something like that appears.


Thank you !

Did you try "isuniquevalue" validation? (I'm not sure if it's working inside a repeat group)

A php validation should do in any case.

Yup, has to be php-validation. Here are some examples:

Have u tried it? For me blocks even if there is no duplication in between repeated groups.

I have also tried this one with Javascript which blocks the selection of an already selected dropdown value.

No, not these particular examples. I trusted Hugh's expertise on that

And you seem to be right, these examples do not work with at least databasejoin element. Didn't go to troubleshoot these particular examples, but diged out what I have been used successfully:

if (is_array($formModel->formData['table___your-dbjoin-element_raw'])) {
  $allValues = array();
  foreach ($formModel->formData['table___your-dbjoin-element_raw'] as $thisArray) {
    $allValues = array_merge($allValues, $thisArray);
  }
  return count(array_unique($allValues)) === count($allValues);
}
return true;

Yes, I was referring to the database join element.
And yes the above works as expected
Thanks.
