Describe the bug

The following code is mentioned in "Validating $_POST data":

`public function updateUser(int $userID)
{
if (! $this->validate([
'email' => "required|is_unique[users.email,id,{$userID}]",
'name' => 'required|alpha_numeric_spaces'
]))
{
return view('users/update', [
'errors' => $this->errors
]);
}

// do something here if successful...

}`

This code gives the impression that the controller class has a variable called "$errors" but this is not the case.

A solution is to use \Config\Services::validation()->getErrors() instead of $this->errors.

PS: The same applies for the second example code in the same section!

CodeIgniter 4 version
CodeIgniter 4 Alpha 2

please try latest develop branch, I can see that it already uses $this->validator->getErrors() at https://github.com/codeigniter4/CodeIgniter4/blob/develop/user_guide_src/source/incoming/controllers.rst#validating-_post-data
