My problem is this:

I uploaded the data to the view banner, which is included in the view main, which in turn is expanded in the home view, is working well. But when I try to access another view (view create-lemma) in which the view main is also expanded, the following error appears:

Undefined variable: motto (View: C: \ xampp \ htdocs \ GEIGRE \ resources \ views \ pages \ banner.blade.php) (View: C: \ xampp \ htdocs \ GEIGRE \ resources \ views \ pages \ banner.blade.php) (View: C: \ xampp \ htdocs \ GEIGRE \ resources \ views \ pages \ banner.blade.php)

I need help. And thank you in advance.

Here's the code.

LemaController

public function create()
{
    $lema=new Lema;
    $lema->texto_lm = Input::get('texto');
    $lema->refBilblica_lm = Input::get('refBiblica');
    $lema->status_lm = Input::get('status');
    $lema->save();
    return redirect('/');
}

HomeController

use App\Lema;
use Redirect;

class HomeController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $lema = Lema:: where('status_lm', 'Activo')->get();

        return view('home')->with('lema',$lema);
    }
 }

Route

Route::get('criar-lema', function () {
    return view('lema.create-lema');
});


Route::post('criar-lema', 'LemaController@create');

Route::get('/', 'HomeController@index');

view banner

<div class="page-header page-header-home">

    <div class="container" style="margin-bottom: 0px; background-color: #85B200">

I think the problem is this here:

Route::get('criar-lema', function () {
    return view('lema.create-lema');
});

In your index() method, you are passing the motto in the ->with() method. In the above method, you are returning the direct view on the route.

If you pass route to a controller, you can reuse the logic of how you are catching the lemmas and switch back to the view whenever you need them. Example:

ROUTE:

Route::get('criar-lema', 'LemaController@showCreate');

CONTROLLER (Main, Controller.php)

protected function getLemas() {
    return Lema::where('status_lm', 'Activo')->get();
}

LEMA CONTROLLER

public function showCreate() {
    return view('lema.create-lema')->with('lema', $this->getLemas());
}

public function create()
{
    $lema=new Lema;
    $lema->texto_lm = Input::get('texto');
    $lema->refBilblica_lm = Input::get('refBiblica');
    $lema->status_lm = Input::get('status');
    $lema->save();
    return redirect('/');
}

HOME CONTROLLER

public function index() {
    return view('home')->with('lema', $this->getLemas());
}
