I am trying to: access a select-field value in my custom validator (https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_validate)

I expected to see: the ID of the post that is selected so i can get the related posts with this function: https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_post

Instead, I got: no value of the selected item

Here is the relevant part of the validator that I'm using:

add_filter('cred_form_validate','pkwFormValidation',10,2);
function pkwFormValidation($error_fields, $form_data)
{
    //field data are field values and errors
    list($fields,$errors)=$error_fields;
    
// this returns nothing (and yes there is a value selected in the form): 
    print_r($fields['@pkw-fahrzeugbuchung.parent']["value"]);
	(...)
}

this is the shortcode of the form:

[cred_field field='@pkw-fahrzeugbuchung.parent' class='form-control' output='bootstrap' select_text='Wählen Sie das Auto aus, das Sie reservieren möchten' value='[wpv-post-id]' ]

The shortcode above represents a relation to another post type. [wpv-post-id] in this context is the id of the related Post.

Hello. Thank you for contacting the Toolset support.

Well - I checked with the following code and I see the parent field value is displayed with $_POST AND $fields:

add_filter('cred_form_validate','cred_filetype_size_validation',10,2);
function cred_filetype_size_validation($field_data, $form_data){
    list($fields,$errors)=$field_data;
    if ( 9999 == $form_data['id'] ) {
	
		echo "<pre>";
		print_r($_POST);
		print_r($fields);
		exit;
    }
    return array($fields,$errors);
}

Where:
- Replace 9999 with your form ID

$_POST did the trick. In this variable I get all the data.

But in $fields the value @pkw-fahrzeugbuchung.parent is not filled. thanks.
