我正在运行AngularJS app。
我以前曾在本地跑过，可以发布到本地服务器上。
现在我正在实时服务器上尝试它，但出现以下错误：
Unable to create Reservation.
只要无法发布到服务器，就会从create.php页发布该错误。
有人知道我的代码有什么问题吗？
create.php页面

// get database connection
include_once '../config/database.php';
// instantiate reservation object
include_once '../objects/reserve.php';
$database = new Database();
$db = $database->getConnection();
$reservation = new Reservation($db);
// get posted data
$data = json_decode(file_get_contents("php://input"));
// set product property values
$reservation->name = $data->name;
$reservation->eMail = $data->eMail;
$reservation->phoneNumber = $data->phoneNumber;
$reservation->colorScooter = $data->colorScooter;
$reservation->amountScooters = $data->amountScooters;
$reservation->inputDate = $data->inputDate;
$reservation->returnDate = $data->returnDate;
$reservation->category_id = $data->category_id;
$reservation->created = date('Y-m-d H:i:s');
// create the reservation
if($reservation->create()){

echo '"message": "Reservation was created."';

}
// if unable to create the reservation, tell the user

}

似乎没有设置属性值。
// set product property values
$reservation->name = $data->name;
$reservation->eMail = $data->eMail;
$reservation->phoneNumber = $data->phoneNumber;
$reservation->colorScooter = $data->colorScooter;

$reservation->inputDate = $data->inputDate;
$reservation->returnDate = $data->returnDate;
$reservation->category_id = $data->category_id;
$reservation->created = date('Y-m-d H:i:s');
运行create.php现场直播还是本地直播

添加了2018年11月8日
添加var_dump($product);结果表明变量$product确实返回了表，而$data实际上是问题所在。
var_dump($product);

NULL
["name"]=>

当前状态
如果我打开create.php文件，它确实会创建一个产品，但是如果我使用表格，则会收到错误消息“无法创建产品”。
另外，当我打开create.php文件时，出现以下错误消息：

更新08-12-2018
运行createproduct（）会将post放入create.php
我用google chrome的检查器网络标签检查了它。
{name: "test", email: "test", phone: "test", amount: "test", description: "test", pickup: "test",…}
amount
:
"test"
back
:
"test"
description
:
"test"
email
:
"test"
name
:
"test"
phone
:
"test"
pickup
:
"test"
它还返回代码：200
根据此link的意思是：
200好 此响应代码表示请求成功。
201已创建 这表明请求成功，并且资源已创建。用于确认PUT或POST请求是否成功。
似乎没有在创建新资源，而且什么也没有发布。
答案 0 :(得分：3)
您为什么使用php：// input？为什么不使用$ _POST访问已发布的数据？如果POST请求命中php，则创建全局关联数组$ _POST。每个索引都将与表单中的名称属性之一匹配，并包含其值。
由于php：// input可以是任何东西，因此$ data可以是这种方法所显示的错误。在这种情况下，您尝试从实际上不是对象的对象中分配值（$ reservation-> name = $ data-> name;）。
// get posted data
$data = json_decode(file_get_contents("php://input"));
// set product property values
$reservation->name = $data->name;
$reservation->eMail = $data->eMail;
$reservation->phoneNumber = $data->phoneNumber;
$reservation->colorScooter = $data->colorScooter;
$reservation->amountScooters = $data->amountScooters;
$reservation->inputDate = $data->inputDate;
$reservation->returnDate = $data->returnDate;
$reservation->category_id = $data->category_id;
$reservation->created = date('Y-m-d H:i:s');
阐明$ data的数据类型，并确保无论如何保持不变。 （尝试使用var_dump代替echo或print_r，会授予其他信息）
答案 1 :(得分：1)
确保在执行任何事务之前检查所有变量值和数组值。您可以使用
在任何时候验证它们isset()
和
is_array()
因此，您会清楚地知道哪一个位置不正确。这样您就可以非常清楚地跟踪它。否则，您会通过查找问题来浪费时间。
答案 2 :(得分：1)
file_get_contents("php://input")（var_dump）上得到了什么url: 'http://localhost/api/product/create.php'。这是你想要的吗？从远程调用到本地主机？您不使用'/api/product/create.php'吗？
