那么我如何让它将数据输入数据库呢？我没有收到任何错误消息-只是一个空白屏幕，注册按钮会将我重定向到该屏幕

这个问题的简单解决方案。我想要一些帮助！万分感谢

有几件事需要指出

当您提交表单的代码位于index.php上时，表单会将页面重定向到header.php（我认为这是这里的主要问题。然后您可能会出现错误）

在类标题中。函数寄存器向它们传递了$first\U name、$last\U name、$email\U id、$password，那么当$first\U name被传递到类中时，为什么要用$first\U POST['first\U name']重置$first\U name的值呢

我看到很多大错误

第一。在index.php中，您正在执行以下操作：

$first_name= $_POST['first_name'];
$last_name = $_POST['last_name'];
$email_id = $_POST['email_id'];
$password = $_POST['password'];

$object = new Header();
$object -> Register($first_name, $last_name,$email_id,$password);

然后你再做一遍：

 public function Register($first_name, $last_name, $email_id, $password){
     if(isset($_POST['first_name'])){

     first_name = $_POST['first_name'];
     $last_name = $_POST['last_name'];
     $email_id = $_POST['email_id'];
     $password = $_POST['password'];
     // other stuff

你不应该依赖$u POST或$u GET来完成你的任务 1.已经在参数中询问您需要什么。 2.向你的职能部门谎称它真正需要什么。永远不要依赖super global来完成您的功能

第二，我建议你用它来约束你的价值观

那么，你应该做的是告诉我们你得到了什么错误！它可能是任何东西，从错误的列名到简单的打字错误。为此，请执行以下操作：

var_dump($odb->errorInfo());

您需要使用`$query=$this->odb->prepare（$q）；`，否则，您的数据库句柄超出范围。注意，try-and-catch与抛出异常无关you@YourCommonSense然而，如果你因为这个而给我打分，那么也许你应该在另一篇帖子上，因为他们也使用了$odb->errorInfo（）
