Class 'update_user_info' 未在 \android_login_example\login 中找到。php

Question

说 Class 'update_user_info' 在 \android_login_example\login 中找不到。php 这里是 Login.php...

IDK 发生了什么，但我也尝试删除 update_user_info.php 文件中函数前面的 public！它没有用！我正在为 android 应用创建登录页面和注册页面！

谢谢特蕾西

<?php
require_once 'update_user_info.php';
$db = new update_user_info();

// json response array
$response = array("error" => FALSE);

if (isset($_POST['email']) && isset($_POST['password'])) {

    // receiving the post params
    $email = $_POST['email'];
    $password = $_POST['password'];

    // get the user by email and password
    $user = $db->VerifyUserAuthentication($email, $password);

    if ($user != false) {
        // use is found
        $response["error"] = FALSE;
        $response["uid"] = $user["unique_id"];
        $response["user"]["name"] = $user["name"];
        $response["user"]["email"] = $user["email"];
        $response["user"]["age"] = $user["age"];
        $response["user"]["gender"] = $user["gender"];
        echo json_encode($response);
    } else {
        // user is not found with the credentials
        $response["error"] = TRUE;
        $response["error_msg"] = "Login credentials are wrong. Please try again!";
        echo json_encode($response);
    }
} else {
    // required post params is missing
    $response["error"] = TRUE; 
    $response["error_msg"] = "Required parameters email or password is missing!";
    echo json_encode($response);
}
?>

现在这是update_user_info.php..

<?php
     function StoreUserInfo($name, $email, $password, $gender, $age) {
        $hash = $this->hashFunction($password);
        $encrypted_password = $hash["encrypted"]; // encrypted password
        $salt = $hash["salt"]; // salt

        $stmt = $this->conn->prepare("INSERT INTO android_php_post(name, email,
encrypted_password, salt, gender, age) VALUES(?, ?, ?, ?, ?, ?)");
        $stmt->bind_param("ssssss", $name, $email, $encrypted_password, $salt, $gender, $age);
        $result = $stmt->execute();
        $stmt->close();

        // check for successful store
        if ($result) {
            $stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");

Answer 1

尝试将您的 update_user.info.php 中的代码包装在一些

中

    class update_user_info{
...
}

那里没有 class，只有一些功能...

Answer 2

我不知道为什么，但您尝试创建一个不存在的实例 class update_user_info。这是我正在谈论的代码片段

$db = new update_user_info();

您包含一个包含结构化代码的文件，而不是 objective。只需调用函数即可使用函数 func() 或将代码重写为面向对象。

使用当前代码代替

$user = $db->VerifyUserAuthentication($email, $password);

你应该打电话给

$user = VerifyUserAuthentication($email, $password);

Answer 3

您实际上并没有在 update_user_info.php 中声明一个 class，只是一些函数。

类声明如下：

class MyClass
{

    // Here is a method:
    public function anExampleFunction()
    {
        //...
    }

}

您可以尝试将 class update_user_info { 放在文件的开头，将 } 放在文件的结尾，看看是否适合您；还要在每个成员函数定义前加上public。

如果要将 update_user_info.php 用作 class

，则需要将其封装在 class 中

<?php
class update_user_info {
    function StoreUserInfo($name, $email, $password, $gender, $age) {
        $hash = $this->hashFunction($password);
        $encrypted_password = $hash["encrypted"]; // encrypted password
        $salt = $hash["salt"]; // salt

        $stmt = $this->conn->prepare("INSERT INTO android_php_post(name, email,
                                        encrypted_password, salt, gender, age) VALUES(?, ?, ?, ?, ?, ?)");
        $stmt->bind_param("ssssss", $name, $email, $encrypted_password, $salt, $gender, $age);
        $result = $stmt->execute();
        $stmt->close();

        // check for successful store
        if ($result) {
            $stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");
            $stmt->bind_param("s", $email);
            $stmt->execute();
            $stmt-> bind_result($token2,$token3,$token4,$token5,$token6,$token7);

            while ( $stmt-> fetch() ) {
                $user["name"] = $token2;
                $user["email"] = $token3;
                $user["gender"] = $token6;
                $user["age"] = $token7;
            }
            $stmt->close();
            return $user;
        } else {
            return false;
        }
    }

    function hashFunction($password) {

        $salt = sha1(rand());
        $salt = substr($salt, 0, 10);
        $encrypted = base64_encode(sha1($password . $salt, true) . $salt);
        $hash = array("salt" => $salt, "encrypted" => $encrypted);
        return $hash;
    }

    function VerifyUserAuthentication($email, $password) {

        $stmt = $this->conn->prepare("SELECT name, email, encrypted_password, salt, gender, age FROM android_php_post WHERE email = ?");

        $stmt->bind_param("s", $email);

        if ($stmt->execute()) {
            $stmt-> bind_result($token2,$token3,$token4,$token5,$token6,$token7);

            while ( $stmt-> fetch() ) {
                $user["name"] = $token2;
                $user["email"] = $token3;
                $user["encrypted_password"] = $token4;
                $user["salt"] = $token5;
                $user["gender"] = $token6;
                $user["age"] = $token7;
            }

            $stmt->close();

            // verifying user password
            $salt = $token5;
            $encrypted_password = $token4;
            $hash = $this->CheckHashFunction($salt, $password);
            // check for password equality
            if ($encrypted_password == $hash) {
                // user authentication details are correct
                return $user;
            }
        } else {
            return NULL;
        }
    }

    function checkHashFunction($salt, $password) {
        $hash = base64_encode(sha1($password . $salt, true) . $salt);
        return $hash;
    }

    function CheckExistingUser($email) {
        $stmt = $this->conn->prepare("SELECT email from android_php_post WHERE email = ?");

        $stmt->bind_param("s", $email);

        $stmt->execute();

        $stmt->store_result();

        if ($stmt->num_rows > 0) {
            // user existed 
            $stmt->close();
            return true;
        } else {
            // user not existed
            $stmt->close();
            return false;
        }
    }
}

或将 class 方法调用转换为普通函数：

$user = $db->VerifyUserAuthentication($email, $password);

至

$user = VerifyUserAuthentication($email, $password);
