how to create select box with data from table?

In your controller, get the tables and pass to the form

$genders = Gender::all();

return view('registration')->withGenders($genders);

The in the form

<select name="gender">
    <option>Select Gender</option>
    @foreach($genders as $gender)
        <option value="{{$gender->id}}">{{$gender->name}}</option>
    @endforeach 
</select>

thank you Mr. Snapey ... I'll try this (y)

to get table which controller i put this? inside RegisterController or make new controller?

I get an error Undefined Variable: genders (View........

You can add it to RegisterController where are you rendering your views(Registration form).

you can try like this

$genders = Gender::all();

return view('registration', compact('genders'));

thanks all, but it's have same error like before.

You are definitely doing something wrong. Can you please show your controller and views where you adding your codes?

it's my RegisterCOntroller:

and this my view:

Have you got it working? I thought you wanted it as part of the registration, but you have created a new view?

In RegisterController.php, add this method, then add the gender stuff to this.

    /**
     * Show the application registration form.
     *
     * @return \Illuminate\Http\Response
     */
    public function showRegistrationForm()
    {

        $genders = Gender::all();

        return view('auth.register')->withGenders($genders);

    }

(and remove it from your create function)

This replaces the same function in the RegistersUsers trait

Then put the select in the auth/register.blade.php view

thank you Sir. it's Solve my problem...
