Question

所以我试图在我的数据库上上传个人资料图片。这是我制作的一个小脚本。我正在使用BLOB，但我尝试了很多事情，但是没有任何反应... 我可能不需要base64编码或解码吗？

有人可以花点时间看一下我的代码吗？提前致谢。：3

    IClock clock,
    IWebDriver driver,
    TimeSpan timeout,
    TimeSpan sleepInterval
)

不要在if statement内准备查询，请为if statement申请$stmt->execute()。像这样修改您的代码

$password =password_hash($_POST['password'],PASSWORD_DEFAULT);
$file=file_get_contents(base64_decode($_FILES['profilepicture'['tmp_name']));
$stmt = $conn->prepare('INSERT INTO `users` (firstname, lastname, email, username, password, groupname, profilepicture) VALUES (?, ?, ?, ?, ?, ?, ?)');
$stmt->bind_param('ssssssb', $_POST['firstname'], $_POST['lastname'], $_POST['email'], $_POST['username'], $password, $_POST['groupname'], $file);
if($stmt->execute()){
      echo 'You have successfully registered, you can now login!';
}else{
      echo 'Could not prepare statement!';
}
