Answer 1

The $request is an object so you can get the properties with ->. Change your controller code as below:

<?php
namespace App\Http\Controllers; // HERE

use Illuminate\Http\Request; // FOR YOUR COMMENT
use App\Http\Requests;
use App\User;
use App\UserTypes;

use Auth;
use Hashids;
use Redirect;
use Request;
use Hash;



class UserController extends controller
{
    public function getdashboard()
    {
        return view('dashboard');
    }

    public function postSignUp(Request $request)
    {
        $email = $request->email;// HERE
        $first_name = $request->first_name;// HERE
        $password = bcrypt($request->password);// HERE


        $user = new User();
        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;

        $user->save();
        return redirect()->route('dashboard');
    }
    public function postSignIn(Request $request)
    {
        if(Auth::attempt([ 'email' => $request->email,'password' => $request->password])){// HERE
            return redirect()->route('dashboard');
        }
        return redirect()->back();
    }
}

Answer 2

There are some laravel usage samples which I would like to link here, and there is a class called Controller at App\Http\Controllers\Controller which you need to use as your base class, but in short, just change your controller namespace from App\Controllers into App\Http\Controllers, or you could even implement the Controller class for your self which could be looking something like below:

<?php
namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

use App\User;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;

class UserController extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function postSignUp(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email|unique:users',
            'first_name' => 'required|max:120',
            'password' => 'required|min:4'
        ]);
        $email = $request['email'];
        $first_name = $request['first_name'];
        $password = bcrypt($request['password']);
        $user = new User();
        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;
        $user->save();
        Auth::login($user);
        return redirect()->route('dashboard');
    }
    public function postSignIn(Request $request)
    {
        $this->validate($request, [
            'email' => 'required',
            'password' => 'required'
        ]);
        if (Auth::attempt(['email' => $request['email'], 'password' => $request['password']])) {
            return redirect()->route('dashboard');
        }
        return redirect()->back();
    }
    public function getLogout()
    {
        Auth::logout();
        return redirect()->route('home');
    }
    public function getAccount()
    {
        return view('account', ['user' => Auth::user()]);
    }
    public function postSaveAccount(Request $request)
    {
        $this->validate($request, [
           'first_name' => 'required|max:120'
        ]);
        $user = Auth::user();
        $old_name = $user->first_name;
        $user->first_name = $request['first_name'];
        $user->update();
        $file = $request->file('image');
        $filename = $request['first_name'] . '-' . $user->id . '.jpg';
        $old_filename = $old_name . '-' . $user->id . '.jpg';
        $update = false;
        if (Storage::disk('local')->has($old_filename)) {
            $old_file = Storage::disk('local')->get($old_filename);
            Storage::disk('local')->put($filename, $old_file);
            $update = true;
        }
        if ($file) {
            Storage::disk('local')->put($filename, File::get($file));
        }
        if ($update && $old_filename !== $filename) {
            Storage::delete($old_filename);
        }
        return redirect()->route('account');
    }
    public function getUserImage($filename)
    {
        $file = Storage::disk('local')->get($filename);
        return new Response($file, 200);
    }
}

Note that PHP is case-insensitive for the class naming, but you could use and extend \App\Http\Controllers\Controller instead of just controller

Answer 3

Your name space is wrong for accessing the Controllers folder, the first line of the code on the controller file change:

namespace App\Controllers;

to

namespace App\Http\Controllers;

also change this part in case if you have this error (Cannot use object of type Illuminate\Support\Facades\Request as array):

use Request;  to  use Illuminate\Http\Request;

and

$email = $request['email'];
$first_name = $request['first_name'];
$password = bcrypt($request['password']);

to

$email = $request->email;
 $first_name = $request->first_name;
 $password = bcrypt($request->password);

Answer 4

By default laravel places controller under

app\Http\Controllers

therefore, replace namespace App\Controllers; by namespace App\Http\Controllers;

Edit:

Access the variable of request like following:

 $email = $request->input('email');
 $first_name = $request->input('first_name');
 //similar way for other inputs
