将数据从textarea传递到函数和路由

Question

I am new to web development and have been learning Laravel. I am following a video tutorial series (https://laracasts.com/series/laravel-5-from-scratch). In the series they use a text are to pass data to a post controller. I would like the user to input their name. If they are in the database, then they are taken to a user's page. I have the Model, database, and migrations working.

For the index page, routing:

Route::get('/','UserController@index');
Route::get('/user', UserController@checked');
Route::get('/accesdenied','UserController@accessdenied');

index view:

    <h1>Welcome</h1>
    <h1>Please enter User Name</h1>
    <form>
       <div>
           <textarea name="body"></textarea> 
           <button type="submit">Access</button>
       </div>     
    </form>

controller:

class UserController extends Controller
{
    public function index()
    {
        return view('users.index');//view is in users folder
    }
    public function check(Request $request)
    {
        $user = DB::table('users')->where('name', $request->body)->first();
        if (isset($user))
            return view(‘users.checked’, compact(‘user’));
        else
            return view('users.accessdenied');//is it right to direct to a page back to a controller?
    }   
    public function accessdenied(Request $request)
    {
        //try again is same as index page with text added
        return view('users.tryagain');
    }   
} 

I have no idea what to pass from the form.

Thank you.

just do a small change

<h1>Welcome</h1>
<h1>Please enter User Name</h1>
<form method="get" action="{{ action('UserController@checked') }}">
   <div>
       <textarea name="body"></textarea> 
       <button type="submit">Access</button>
   </div>     
</form>
