用户登录错误

Question

(对不起，如果这是一个nooby问题-我是PhP的新手)

因此，我已经很好地设置了注册页面，并将其添加到MySQL数据库中，但是，当我使用正确的详细信息登录时，会得到错误：

PHP致命错误:调用未定义的方法用户：：authenticate()

这是我的ClassUser代码

`

     function __construct() {
         if(session_id() == "") {
             session_start();
         }
    if (isset($_SESSION['isLoggedIn']) && $_SESSION['isLoggedIn'] == true) {
        $this->_initUser();
    }
}//end__construct

public function autheniticate($user,$pass) {
    $mysqli = new mysqli(DBHOST,DBUSER,DBPASS,DB);
    if ($mysqli->connect_errno) {
        error_log("Cannot connect to MySQL: " . $mysqli->connect_error);
        return false;
    }
    $safeUser = $mysqli->real_escape_string($user);
    $incomingPassword = $mysqli->real_escape_string($pass);
    $query = "SELECT * from Customer WHERE email = '{$safeUser}'";
    if (!$result = $mysqli->query($query)) {
        error_log("Cannot retrieve account for {$user}");
        return false;
    }
    //Will be obly one row, so no while() loop needed
    $row = $result->fetch_assoc();
    $dbPassword = $row['password'];

    if (crypt($incomingPassword, $dbPassword) != $dbPassword ) {
        error_log("Passwords for {user} don't match");
        return false;
    }

    $this->id = $row['id'];
    $this->username = $row['username'];
    $this->isLoggedIn = true;

    $this->_setSesstion();

    return true;
}//end function authenticate

private function _setSession() {

    if(session_id() == '') {
        session_start();
    }

    $_SESSION['id'] = $this->id;
    $_SESSION['username'] = $this->username;
    $_SESSION['isLoggedIn'] = $this->isLoggedIn;

}//end function setSession

private function _initUser() {

    if(session_id() == '') {
        session_start();
    }

    $this->id = $_SESSION['id'];
    $this->username = $_SESSION['username'];
    $this->isLoggedIn = $_SESSION['isLoggedIn'];

}//end function initUser
 }//end classUser

 ?>`

这是我的登录流程代码；

`

 require_once('functions.inc');

 //prevent access if they haven't submitted the form
 if (!isset($_POST['submit'])) {
     die(header("Location: login.php"));
 }

 $_SESSION['formAttempt'] = true;

 if(isset($_SESSION['error'])) {
     unset($_SESSION['error']);
 }
 $_SESSION['error'] = array();

 $required = array("username","password");

 //Check required fields
 foreach ($required as $requiredField) {
     if (!isset($_POST[$requiredField]) || $_POST[$requiredField] == "") {
         $_SESSION['error'][] = $requiredField . " is required.";
     }
 }

 if (count($_SESSION['error']) > 0) {
     die(header("Location: login.php"));
 } else {
     $user = new User;
     if($user->authenticate($_POST['email'],$_POST['password'])) {
         unset($_SESSION['formAttempt']);
         die(header("Location: authenticated.php"));

任何帮助都将不胜感激！谢谢

您定义的函数名是：

// You are misspelling "authenticate"
autheniticate($user,$pass)

但你在打电话：

authenticate()
