<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;

class LoginController extends Controller
{
public function login(Request $request){

    if($request->method()=='POST'){

    }
    return view('login.login');
}

public function register(Request $request){
    if($request->method()=='POST'){
        $this->validate(request(),[
            'name'=>'required|min:4|unique:users,name',
            'email'=>'required|unique:users,email|email',
            'password'=>'required|min:6|confirmed'
        ]);

        $password = bcrypt($request->input('password'));
        $name = $request->input('name');
        $email = $request->input('email');

        $user = User::create(['name'=>$name,'email'=>$email,'password'=>$password]);
        if($user){
            return redirect()->route('login');
        }

    }

    return view('login.register');
}
