Laravel 5 - Validation error on form doesn't re-enter user input

Entering data on a form that throws a validation error, doesn't re-input the user's previous input.

public function store(ClinicFormRequest $request)
    {

        $user = new \App\User;
        $user->name = $request->name;
        $user->email = $request->email;
        $user->password = Hash::make(str_random(10));
        $user->save();

        $user->user_id;

        $clinic = new \App\Clinic;
        $clinic->name = $request->clinicname;
        $clinic->telephone = $request->telephone;
        $clinic->save();

        $clinic->users()->attach(user_id);

        return Redirect::route('clinic.index')->with('message', 'Clinic created');

    }

Clinic Form Reqeust:

class ClinicFormRequest extends Request {

    public function authorize()
    {
        return true;
    }

    public function rules()
    {
