Route::post('/contact', 'contactController@submit_contact')->name('submitContactMessage');

   protected $fillable = [
        'name', 'email', 'subject', 'message'
    ];

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ContactController extends Controller
{
    public function contact()
    {
        return view('contact');
    }

    public function submit_contact(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'email' => 'required',
            'subject' => 'required',
            'message' => 'required'
        ]);

        Contact::create($request->except('_token'));

        flash('پیام شما با موفقیت ارسال شد.')->success();
        return redirect(route('viewContactPage'));
    }
