我是PHP新手。我在我的项目中使用下面的代码,但是它不起作用,但是没有引发任何错误。我试图将其转换为GET方法,但仍然无法正常工作。

PHP是我的前端,而MySQL数据库是后端。

我已经在后端创建了表,并检查了用户表,但没有插入值。

尝试的方法:

我已经使用insert命令手动插入了数据,并且工作正常。

API调用

http://localhost/test/register.php?phone=12345&name=Smith&birthdate=1974-12-01&address=7th Avenue

错误:

{"error_msg":"Required parameter (phone,name,birthdate,address) is missing!"}

Register.php

<?php
require_once 'db_functions.php';
$db=new DB_Functions();
$response=array();
if(isset($_POST['phone']) &&
isset($_POST['name']) &&
isset($_POST['birthdate']) &&
isset($_POST['address']))

{
    $phone=$_POST['phone'];
    $name=$_POST['name'];
    $birthdate=$_POST['birthdate'];
    $address=$_POST['address'];

    if($db->checkExistsUser($phone))
    {
        $response["error_msg"]="User already exists with" .$phone;
        echo json_encode($response);
    }
    else
    {
       //Create new user
        $user=$db->registerNewUser($phone,$name,$birthdate,$address);

        if($user)
        {
            $response["phone"]=$user["Phone"];
            $response["name"]=$user["Name"];
            $response["birthdate"]=$user["Birthdate"];
            $response["address"]=$user["Address"];

            echo json_encode($response);
        }
        else
        {
            $response["error_msg"]="Unknown Error occurred in registration!";
            echo json_encode($response);
        }

姓名,电话,地址和出生日期值需要插入MYSQL数据库中。

您的URL调用是GET方法,但是您正在查询POST变量。

因此,基本上,您的if语句导致为false,从而导致错误消息。将它们更改为GET。

if(isset($_GET['phone']) &&
isset($_GET['name']) &&
isset($_GET['birthdate']) &&
isset($_GET['address']))

然后它应该工作
