php - Ionic + Angular + PHP 未定义属性:insert.php 中的 stdClass::$variable

Question

一共有三个文件。当在 ionic 页面中单击提交按钮时，它会将所有输入发送到 Controller ，然后 Controller 将解析到 insert.php。当我只使用html(没有ionic内容)时，表单输入数据被保存，但当我使用IONIC时，表单将空数据发送到mysql数据库。我从 Firebug 中发现的错误是:1. 响应 - 注意:insert.php 中未定义属性:stdClass::$firstname2. POST (JSON) - 没有子对象请帮助我，下面是我的文件。

第 3 页 - Insert.php

 <?php
 $data = json_decode(file_get_contents("php://input"),true);
 var_dump($data);die;
$firstname = $data->firstname;
$lastname = $data->lastname;
$email = $data->email;
$telephone = $data->telephone;

 mysql_connect("localhost","root","");
 mysql_select_db("example_demo");
 $singam = "INSERT INTO `tbl_order`(`firstname`,`lastname`,`email`,`telephone`)
 VALUES('".$firstname."','".$lastname."','".$email."','".$telephone."')";

 mysql_query($singam);
//      var_dump(mysql_fetch_assoc($singam));die;
 ?>

Answer 1

不要使用这个，

$data = json_decode(file_get_contents("php://input"),true);
var_dump($data);die;
$firstname = $data->firstname;

尝试使用$_POST类似的东西，

$firstname = $_POST['firstname'];
