#if ($errors->any())
#foreach ($errors->all() as $error)
{{ $error }}
#endforeach
#endif
can anyone help me to solve this issue.

Answer 1

If there are validation errors, you should use $errors in your view to get them. The $errors variable is an instance of Illuminate\Support\MessageBag and Laravel always makes it available to your views. You can use it like this:
#if ($errors->any())
<div class="errors">
#foreach ($errors->all() as $message)
<p>{{ $message }}</p>
#endforeach
</div>
#endif
That will output all of your validation messages (if there are any) to your view. If you want to check to see if there's an error message for a specific field, you can use the has method. You can then use the first message to retrieve the first message for that field or the get method to retrieve them all. An example using first:
#if ($errors->has('your_field'))
<div class="error">{{ $errors->first('your_field') }}</div>
#endif
See here for more information

Answer 2

Validation messages are stored in $errors, which is globally passed to all views, and not in session()->get("message"), unless you specifically used that. With the above, you'd use
#if($errors->has("first_name"))
<p class="alert alert-info">{{ $errors->first("first_name") }}</p>
#endif
Do the same for all fields being validated and you should start seeing your error messages.

Do you override the function "showRegistrationForm"?
If Yes, you should override the function "register":
public function register(Request $request) {
$validation = $this->validator($request->all());
if ($validation->fails()) {
$errors = $validation->errors();
return view('auth.register', compact('errors'));
}
else {
$user = $this->create($request->all());
Auth::login($user);
return redirect('/')->with(['message'=>'Account Successfully Created.']);
}
}
