Программно добавить заказ D7

Скрипт js, в котором собираем необходимые данные в sendData и с помощью ajax отправляем их в файл обработки order.php:

var form = $('.registr__desc'),
    btn = $('.registr__btn');
function checkInput(){
    $('.registr__desc').find('.required').each(function(){
        if($(this).val() != ''){
            $(this).removeClass('empty_field');
            $(this).removeAttr('style');
        } else {
            $(this).addClass('empty_field');
        }
    });
}
function lightEmpty(){
    form.find('.empty_field').css({'border-color':'rgba(217, 31, 67, 0.5)'});
    $(".alert_required").text("Заполнены не все поля");
}
setInterval(function(){
    checkInput();
    var sizeEmpty = form.find('.empty_field').size();
    if(sizeEmpty > 0){
        if(btn.hasClass('disabled')){
            return false

Скрипт создания заказа содержит в себе неточности, касающиеся создания нового пользователя, а также добавления заказа только для одного типа плательщика, что легко может быть доработано посредством передачи и получения необходимых полей.
