Question

<?php

require("config.inc.php");

//if posted data is not empty
if (!empty($_POST)) {

if (empty($_POST['username']) || empty($_POST['password'])) {


    // Create some data that will be the JSON response 
    $response["success"] = 0;
    $response["message"] = "Please Enter Both a Username and Password.";

    die(json_encode($response));
}
else if (empty($_POST['name']) || empty($_POST['mobilenumber']) || empty($_POST['address']) || empty($_POST['city']) || empty($_POST['state'])) {

    // Create some data that will be the JSON response 
    $response["success"] = 0;
    $response["message"] = "Please Enter the required marked ** field.";

    die(json_encode($response));
}
else if (strlen($_POST['password']) < 6) {
$response["success"] = 0;
    $response["message"] = "Your password should be at least 6 characters.";
die(json_encode($response));               
}
else if ($_POST['password'] != $_POST['confirmpassword']){
    $response["success"] = 0;
    $response["message"] = "Confirm Password is not the same with Password you have entered.";
die(json_encode($response));
}

$query        = " SELECT 1 FROM user WHERE email = :email";
$query_params = array(
    ':email' => $_POST['username']
);

//Now let's make run the query:
try {
    // These two statements run the query against your database table. 
    $stmt   = $db->prepare($query);
    $result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
    // For testing, you could use a die and message. 
    //die("Failed to run query: " . $ex->getMessage());

    //or just use this use this one to product JSON data:
    $response["success"] = 0;
    $response["message"] = "Database Error1. Please Try Again!";
    die(json_encode($response));
}

//fetch is an array of returned data.  If any data is returned,
//we know that the username is already in use, so we murder our
//page
$row = $stmt->fetch();
if ($row) {
    // For testing, you could use a die and message. 
    //die("This username is already in use");

    //You could comment out the above die and use this one:
    $response["success"] = 0;
    $response["message"] = "I'm sorry, this username is already in use";
    die(json_encode($response));
}
$query = "INSERT INTO user ( name, email, password, mobilenumber, address, city, postcode, state) VALUES ( ;name, :email, :password, :mobilenumber, :address, :city, :postcode, :state) ";

//Again, we need to update our tokens with the actual data:
$query_params = array(
    ':name' => $_POST['name'],
    ':email' => $_POST['username'],
    ':password' => $_POST['password'],
    ':mobilenumber' => $_POST['mobilenumber'],
    ':address' => $_POST['address'],
':city' => $_POST['city'],
    ':postcode' => $_POST['postcode'],
':state' => $_POST['state']
);

//time to run our query, and create the user
try {
    $stmt   = $db->prepare($query);
    $result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
    // For testing, you could use a die and message. 
    //die("Failed to run query: " . $ex->getMessage());

    //or just use this use this one:
    $response["success"] = 0;
    $response["message"] = "Database Error2. Please Try Again!";
    die(json_encode($response));
}

//If we have made it this far without dying, we have successfully added
//a new user to our database.  We could do a few things here, such as 
//redirect to the login page.  Instead we are going to echo out some
//json data that will be read by the Android application, which will login
//the user (or redirect to a different activity, I'm not sure yet..)
$response["success"] = 1;
$response["message"] = "Username Successfully Added!";
echo json_encode($response);

//for a php webservice you could do a simple redirect and die.
//header("Location: login.php"); 
//die("Redirecting to login.php");

这是我收到的消息 {“成功”：0，“消息”：“数据库错误2.请再试一次！”} 我不知道程序有什么特别之处...，任何人都可以帮助我吗？ 非常感谢大家的帮助。 如果需要任何其他编码我可以在这里给它。

Answer 1

$query = "INSERT INTO user ( name, email, password, mobilenumber, address, city, postcode, state) VALUES ( ;name, :email, :password, :mobilenumber, :address, :city, :postcode, :state) ";

更改为

$query = "INSERT INTO user ( name, email, password, mobilenumber, address, city, postcode, state) VALUES ( :name, :email, :password, :mobilenumber, :address, :city, :postcode, :state) ";
