Creating a message of success when able to perform an action LARAVEL 5.4

Question

I’m trying to get you informed a message of success in a div when an action is carried out, however I could not yet, the error that appears is:

(3/3) Errorexception Undefined variable: sucess (View: /opt/lampp/htdocs/projetoslaravel/clinica-beta/Resources/views/layouts/app.blade.php) (View: /opt/lampp/htdocs/projetoslaravel/clinica-beta/Resources/views/layouts/app.blade.php)

my code is as follows on the page layout

@if(isset($errors) and count($errors) > 0)
     <div id="msg" class="alert alert-error">                
                <p>{{$error}}</p>
     </div>           
@elseif(isset($sucess) and count($sucess) > 0)
     <div id="msg" class="alert alert-sucess">                
                <p>{{$sucess}}</p>
     </div>
@endif

in the controller as follows

public function ativar($id) 
{
    $apt = $this->ModelApartamento->find($id);
    $liberacao = $apt->verificarAtivar();
    if ($liberacao) {
        $dados = ['status' => 'L'];
        //dd($dados);
        $update = $apt->update($dados);
        if ($update) {
            return redirect()
                   ->back()
                   ->with('sucess','Apartamento ativado com sucesso'); 
        } else {
            return redirect()
                   ->back()
                   ->with('errors', 'Ocorreu um erro ao tentar ativar apartamento');
        }
    } else {
        return redirect()
                   ->back()
                   ->with('errors', 'Apartamento está com paciente no momento');
    }
}

There are several ways to make a status, in my view yours is wrong, including because your test in the if does not correctly test the variables and could be done for example as follows:

Create a variable from a predefined class in PHP, i.e., stdClass, and in the code of controller make these changes:

public function ativar($id) 
{
    $apt = $this->ModelApartamento->find($id);
    $liberacao = $apt->verificarAtivar();

    $st = new StdClass;

    if ($liberacao) 
    {
        $dados = ['status' => 'L'];        
        $update = $apt->update($dados);
        if ($update) 
        {
            $st->status = true;
            $st->message = "Apartamento ativado com sucesso";
            return redirect()
                   ->back()
                   ->with('st', $st); 
        } 
        else 
        {
            $st->status = false;
            $st->message = "Ocorreu um erro ao tentar ativar apartamento";
            return redirect()
                   ->back()
                   ->with('st', $st);
        }
    } 
    else 
    {
        $st->status = false;
        $st->message = "Apartamento está com paciente no momento";
        return redirect()
                   ->back()
                   ->with('st', $st);
    }
}

and in the View also make these changes:

@if(session()->has('st'))
@if(!session()->get('st')->status)
    <div id="msg" class="alert alert-error">                
        <p>{{$st->message}}</p>
    </div>           
@else
    <div id="msg" class="alert alert-sucess">                
        <p>{{$st->message}}</p>
    </div>
@endif
@endif

could still get better at your View as follows:

@if(session()->has('st'))
<div 
  id="msg" 
  class="@if(session()->get('st')->status){{'alert alert-sucess'}}@else{{'alert alert-error'}}@endif">
    <p>{{$st->message}}</p>
</div>
@endif

that would be one of the ways.
