一直在打这个代码得到了大部分错误,但现在我得到了这个错误消息

  

致命错误:在第26行的/home/jsnow/public_html/registration.php中调用非对象的成员函数prepare()

这是我的代码:

<?php

if(isset($_POST['username']) && isset($_POST['password']))
{
$db =connect('********','*********');
if($db!=false)
{
   register($db);
   echo "User registered";
}

}

function connect($dbuser,$dbpassword)
{
    try{
        $db = new PDO('mysql:host=localhost;dbname=jsnow_login', '*******' , '*********');
        return $db;
    }catch(PDOException $e){
        echo $e;
        return false;}
}

function register($db)
{
    $result_set = $pdo->prepare("INSERT INTO `users` (`username`, `password`) 
                            VALUES (:username, :password)");
 $result_set->execute(array(
':username' => $username, ':password' => $password
));

}




?>

答案 0 :(得分:1)

register()内,未定义$pdo。请改用以下内容:

$result_set = $db->prepare("INSERT INTO `users` (`username`, `password`) 
                        VALUES (:username, :password)");

关于$sername$password变量未在函数中初始化,请将函数定义更改为:

function register($db,$username,$password)

并将其称为:

register($db,$_POST['username'],$_POST['password']);
