Random number/string in hidden field

Hi @graphixz

I hope you are doing well today.

I pinged our SLS Team to review your query and see what will be possible in this case. We will post an update here as soon as more information is available.

Kind Regards,
Kris

Hi again @graphixz

Please us this snippet as a mu-plugin:

add_filter( 'forminator_prepared_data', 'wpmudev_random_user_hidden_field', 10, 2 );
function wpmudev_random_user_hidden_field( $prepared_data, $module_object ){
	if ( 1771 != $module_object->id ) { // Please change the form ID.
		return $prepared_data;
	}

    foreach ( $prepared_data as $key => $value ) {
        if ( '{random_user}' == $value ) {
            $prepared_data[$key] = 'USR' . random_int( 100000, 999999 );
        }
    }
	return $prepared_data;
}

add_action( 'forminator_custom_form_submit_before_set_fields', 'wpmudev_user_hidden_field_data', 10, 3 );
function wpmudev_user_hidden_field_data( $entry, $module_id, $field_data_array ) {
    $form_ids = array( 1771 ); // Please change the form ID.
	if ( ! in_array( $module_id, $form_ids ) ) {
		return;
	}
    
    foreach ( $field_data_array as $key => $value ) {
        if ( '{random_user}' == $value['value'] ) {
            Forminator_CForm_Front_Action::$info['field_data_array'][$key]['value'] = sanitize_text_field( Forminator_CForm_Front_Action::$prepared_data[ $value['name'] ] );
        }
    }
}

Please change 1771 to your form ID twice in above code. In your hidden field please use Custom Value and type “{random_user}”.
