Input validation return empty array

Hi ozornick,
thanks a lot for taking time to check the code and for your feedback.
It's really weird...since I cannot get the validated data...if I edit the code using the getPost() I can see the input POST data...[/url]

You can see the working page at the following link: [url=https://aeclidb.it/census/collection]https://aeclidb.it/census/collection

In the page ( a paginated gallery ) there are a couple of input field: a select and one autocomplete input text. A jQuery code submit the form as soon as selected a region or an item in the autocomplete list.
I don't think that the issue could be related to the Javascript code....
Thanks a lot for any help

EDIT: I just realized that in your code validated is:

Code:

["validated"]=>
  array(0) {
  }

Is this correct? I thought I should get the list of input validated...
