Sending email laravel form

I'm trying to send emails with form details in. I succeed to send one with email information but when I'm trying to add more data, i get errors such as undefined var etc.

After sending the mail, I'd like to redirect to a new view saying ' Thx for contacting us" before getting back to index. Any help ? :(

Controller

namespace App\Http\Controllers;

use  App\Http\Requests\ContactFormRequest;

class AboutController extends Controller {
    public function create()
    {
        return view('contact');
    }
    public function store(ContactFormRequest $request)
{

    \Mail::send('emails.hello',
        array(
            'event_type' => $request-> get('event_type'),
            'date' => $request->get('date'),
            'personnes' => $request->get('personnes'),
            'lieu' =>'lieu',
            'rayon_km' => $request->get('rayon_km'),
            'accessoires' => $request->get('accessoires'),
            'civilite' => $request->get('civilite'),
            'nom' => $request->get('nom'),
            'prenom' => $request->get('prenom'),
            'email' => $request->get('email'),
            'telephone' => $request->get('telephone'),
            'telephone2' => $request->get('telephone2'),
            'horaires' => $request->get('horaires'),
        ), 

        function($message)
    {
        $message->from('wj@wjgilmore.com');
        $message->to('x@gmail.com', 'Admin')->subject('Form');
    });

  return \Redirect::route('contact')->with('message', 'Thanks for contacting us!');
}}
