Question

我已经创建了一个非常基本的PHP创建用户表单，在我的个人计算机上它工作正常但是因为找到一个合适的主机我遇到了错误不停。第一个是使用Date我是不安全的，所以我禁用了它，现在我没有错误，但它没有插入数据到表并重定向到index.php但是我所有的看到的是一个空白的白页。有什么帮助吗？

    <?PHP
include'../include_htm/global.htm';

error_reporting(-1);

//Connect to server and select databse.
$link = mysqli_connect("$DB_HOST", "$DB_USER", "$DB_PASS", "$DB_NAME") 
    or die ('Could not connect to database!');

//Grab information from post page
$reg_username=$_POST['username']; 
$reg_password=$_POST['password'];  
$email=$_POST['email'];
$avatar=$_POST['avatar'];

if($avatar == null) {
    header("location:../register.php?no_avatar=true");
}
else
{
//Set variables
//$date = date('j\/m\/Y');
$false = "false";
$ipaddress = $_SERVER["REMOTE_ADDR"];
$role = "user";

//Encrypt Password With MD5
$encrypt_password=hash('sha256', $reg_password);

//Insert Information
$query = "INSERT INTO $DB_TABLE (username, password, email, role, ipaddress, avatar) VALUES ('$reg_username', '$encrypt_password', '$email', '$role', '$ipaddress', '$avatar')";

mysqli_query($link, $query);
mysqli_close($link);

//Select login details from database
$_SESSION['user'] = $reg_username;

//$query1 = "UPDATE $DB_TABLE SET avatar='$avatar' WHERE `username`='$reg_username'";
//mysqli_query($link, $query1);
//mysqli_close($link);

header("location:../index.php?welcome=true");
}
?>

Answer 1

//Insert Information
$stmt = $link->prepare("INSERT INTO `$DB_TABLE` (`username`, `password`, `email`, `role`, `ipaddress`, `avatar`) VALUES (?,?,?,?,?,?)");

/* bind parameters for markers */
$stmt->bind_param("ssssss", $reg_username, $encrypt_password, $email, $role, $ipaddress, $avatar);

/* execute query */
$stmt->execute();
mysqli_close($link);

PHP / MySQLi Insert返回空白页面
