Your method needs 5 arguments, you only pass 2: User->register('ds', 'dsssssss')
您的方法需要 5 个参数，您只需传递 2 个： User->register('ds', 'dsssssss')
Edit this line in Register.php:
编辑此行Register.php：
$user->register($username, $password)
to
到
$user->register($name, $surname, $username, $password, $email)
Additionally you have this line twice $stmt->bindParam(":password", $password);
另外你有这行两次 $stmt->bindParam(":password", $password);

In php 7 instead of:
在 php 7 中，而不是：
public function register($name, $surname, $username, $password, $email)
{
...
use:
用：
public function register($name = null, $surname = null, $username = null, $password = null, $email = null)
{
...

I experienced this same error after my hosting company updated our PHP version from 7.0.x to 7.1.x. They assumed that since it was a minor update, it should be compatible with previous versions. They were wrong: here'sa list of the incompatibilities from the migration page.
在我的托管公司将我们的 PHP 版本从 7.0.x 更新到 7.1.x 后，我遇到了同样的错误。他们认为由于这是一个小更新，它应该与以前的版本兼容。他们错了：这是迁移页面中的不兼容性列表。
In this particular case code that would previously throw a warning about the lack of parameters for a function call is now throwing the fatal error in the OP's question.
在这种特殊情况下，以前会抛出有关函数调用缺少参数的警告的代码现在在 OP 的问题中抛出致命错误。
The solution is obviously to provide the appropriate parameters as the other answers have indicated.
解决方案显然是提供适当的参数，如其他答案所示。

For anyone who encountered this error or something similar, the answer below works! I encountered this error when trying to get an older version of WordPress WooCommerce to run on PHP 7.2. Lol, I know. The WooCommerce Product Edit Screen was blank with the error below (which broke the product tabs)
