Hi, I need help
I'm trying to make cred form
and I need required taxonomy select box and show up the error message but I can't don't know how

I added this filter in functions.php

add_filter('cred_form_validate','price_validation',10,2);
function price_validation($field_data, $form_data) {
list($fields,$errors)=$field_data;
if ($form_data['id']==5031) {
if (empty($fields['price']['value'][0]))
$errors['price']='Please select a topic';
}
return array($fields,$errors);
}

and this is cred field
[cred_field field='price' force_type='taxonomy' output='bootstrap' display='select' single_select='true' data-parsley-required="true" ]

Is there any documentation that you are following?
