我在用户表单中上传图像的代码有什么问题？

Question

我正在开发一个 MySQL 和 PHP 项目，在该项目中我创建了一个表单来捕获用户详细信息，包括他们的护照。但是，当用户填写表单并单击“提交”时，页面会变为空白，并且数据不会插入到数据库中。奇怪的是，图像确实被移动到指定的目录。我需要帮助解决这个问题以确保一切顺利。以下是我的代码，主要问题是图片上传。

以下是相关的 PHP 和 HTML 代码：

if(isset($_POST['submit']))
{
$name=$_POST['name'];
$image = $_FILES['image']['name'];
$regno=$_POST['regno']; 
$email=$_POST['email']; 
$password=$_POST['password'];
$status=1;
// image file directory
    $target = "images/".basename($image);

    move_uploaded_file($_FILES['image']['tmp_name'], $target);


$sql="INSERT INTO  tblstudents(name,image,regno,email,password,status) VALUES(:name,:image,:regno,:email,:password, :status)";

$query = $dbh->prepare($sql);
$query->bindParam(':name',$name,PDO::PARAM_STR);
$query->bindParam(':image',$_image,PDO::PARAM_STR);
$query->bindParam(':regno',$regno,PDO::PARAM_STR);
$query->bindParam(':email',$email,PDO::PARAM_STR);
$query->bindParam(':password',$password,PDO::PARAM_STR);
$query->bindParam(':status',$status,PDO::PARAM_STR);

$query->execute();
$Id = $dbh->Id();
if($Id)
{
$msg="user added successfully";
}

elseif (move_uploaded_file($_FILES['image']['tmp_name'], $target)) {
        $msg = "Image uploaded successfully";
}else 
{
$error="Something went wrong. Please try again";
}

}
?>

这是我的 html 表单

 <form class="form-horizontal" method="post" enctype="multipart/form-data">
                                                    <!-- image file  enctype="multipart/form-data" -->

                                                    </div>
                                                </form>

我已经解决了这个问题，现在运行良好。我使用数组来捕获所有变量。
