无法使用AngularJS和PHP发布

我正在运行AngularJS 应用程序.

我之前在本地跑过,我可以发布到本地服务器.

现在我在实时服务器上尝试它,我收到以下错误:

Unable to create Reservation.

create.php只要无法发布到服务器,就会从页面发布此错误.

有人知道我的代码有什么问题吗？

It seems it can't find the "name" properties.

I've got the idea whats causing the issue,

Running the createproduct() it does post it into create.php

I checked it with google chrome's inspector network tab.

{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"

it also returns code:200

which according to this link means:

200 OK This response code indicates that the request was successful.

201 Created This indicates the request was successful and a resource was created. It is used to confirm success of a PUT or POST request.

It seems it's not creating new resources and nothing has been posted.

为什么使用 php://input ？您不使用 $_POST 访问发布的数据是否有原因？如果 POST 请求命中 php，则会创建全局关联数组 $_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。

显示的错误可能来自此方法，因为 php://input 可以是任何内容，因此 $data 可以是任何内容。如果是这种情况，您尝试从实际上不是对象的对象中分配值（$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');

澄清 $data 的数据类型并确保它无论如何保持不变。（尝试使用 var_dump 而不是 echo 或 print_r，授予附加信息）
