注意: undefined variable :/home/sultanp1/public_html/includes/handlers/register-handler.php 第 32 行中的帐户

最佳答案
您未能在页面/handlers/register-handler.php 第 32 行之前创建类 Account 的对象:
if(isset ($_POST['registerButton'])){
....
$account = new Account($connectionObject); /* missing line, use appropriate name for connectionObject */
$wasSuccessful = $account->register($username, $first_name, $last_name, $email, $password);
关于php 和 c-panel 令人沮丧，用户似乎没有正确注册到数据库中，我收到错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50195427/
