// the snippet for the form action which currently works looks like this:

function referring_affiliate_form_action ( $atts ) {
	$output_form_action = '';
	if ( !is_admin() ) {
		if ( !class_exists( "Affiliates_Service" ) ) {
			include_once( AFFILIATES_CORE_LIB . '/class-affiliates-service.php' );
		}
		$affiliate_id_form_action = Affiliates_Service::get_referrer_id(); 
		if ( $affiliate_id_form_action && $affiliate_id_form_action != affiliates_get_direct_id() ) {
			if ( $user_id_form_action = affiliates_get_affiliate_user( $affiliate_id_form_action ) ) {
				if ( $user_form_action = get_user_by( 'id', $user_id_form_action ) ) {
					$output_form_action .= '' ;
					if (
						get_user_meta( $user_id_form_action, 'form_action' , true ) &&
						( get_user_meta( $user_id_form_action, 'form_action' , true )!== "" )
					) {
						$output_form_action .=''.get_user_meta( $user_id_form_action, 'form_action' , true ).'';
					}
				}
			}
		}
	}
	return $output_form_action;
}

// The input value shortcode that just renders as a shortcode and doesn't work looks basically the same.
add_action( 'init', 'referring_affiliate_input_value_shortcode' );
