Condition within foreach before saving template

In my% s of CakePHP a Controller was made by passing all the data of a form to a variable.

Now, how do I make a specific% wc, what would your goal be if the foreach is passing is empty, move on to the next?

foreach ($this->request->data['CursoNavigation'] as $indice => $valor) {
    if (empty($valor)) continue;
    // código para continuar e salvar as informações no 'CursoNavigation'
}
