I trying to insert value into database by form in laravel but my all value's is not inserted .
..insert only email,password,created_date
Here is my code of migration :-

    Schema::defaultStringLength(191);
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('fname');
        $table->string('lname');
        $table->string('email')->unique();
        $table->string('phone');
        $table->string('gender');

        $table->string('country');
        $table->string('city');
        $table->string('district');
        $table->string('upozila');
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });

here is code of controller :-

public function register(Request $request)
{
    $this->validation($request);
    User::create($request->all());
    return redirect('/');
}

public function validation($request)
{
    $validatedData = $request->validate([
    'fname' => 'required|max:255',
    'lname' => 'required|max:255',
    'email' => 'required|email|max:255|unique:users,email',
