Filtering when selecting a checkbox

Solution:

In% of% I make a filter for each Controller , in the case of the example below I will only do three:

Controller

  $this->Filter->addFilters(
          array(
              'filter1' => array(
                   'Filtro1.descricao' => array(
                       'operator' => 'ILIKE',
                       'value' => array(
                           'before' => '%',
                           'after' => '%'
                        )
                    )
               )
               'filter2' => array(
                   'Filtro2.descricao' => array(
                       'operator' => 'ILIKE',
                       'value' => array(
                           'before' => '%',
                           'after' => '%'
                        )
                    )
               )
               'filter3' => array(
                   'Filtro3.descricao' => array(
                       'operator' => 'ILIKE',
                       'value' => array(
                           'before' => '%',
                           'after' => '%'
                        )
                    )
               )
          )
   );

Then I initialize the variables that will be used in Checkbox below:

$conditions = array();
$vFiltro = array();
$filtro1 = '';
$filtro2 = '';
$filtro3 = '';

foreach ($this->Filter->getConditions() as $chave => $valor) {
    if ($valor != '%0%') {
        if ($chave == 'Filtro1.descricao ILIKE') {
            $filtro1 = $valor;
        }
        if ($chave == 'Filtro2.descricao ILIKE') {
            $filtro2 = $valor;
        }
        if ($chave == 'Filtro3.descricao ILIKE') {
            $filtro3 = $valor;
        }
    }
}

Next, if the filters are not empty I add each filter in the% conditions variable foreach to make the pagination.

if (!empty($filtro1)) {
    $conditions[] = "Filtro1.descricao ILIKE '" . $filtro1 . "'";
} elseif (!empty($filtro2)) {
    $conditions[] = "Filtro2.descricao ILIKE '" . $filtro2 . "'";
} elseif (!empty($filtro3)) {
    $conditions[] = "Filtro3.descricao ILIKE '" . $filtro3 . "'";
} else {
    $conditions[] = "";
}

After we paginate to show the items we want.

$this->Paginator->settings = array(
    'fields' => array('Ose.id', 'user_nome', 
                      'Status.descricao', 'Group.descricao'),
    'joins' => array(
        array('table' => 'groups',
            'alias' => 'Group',
            'type' => 'LEFT',
            'conditions' => ['User.group_id = Group.id'],
        ),
        array('table' => 'statuses',
            'alias' => 'Status',
            'type' => 'LEFT',
            'conditions' => ['Status.id = Ose.status_id_destino'],
        ),
        array('table' => 'statuses',
            'alias' => 'Filtro1',
            'type' => 'LEFT',
            'conditions' => ['Filtro1.id = Ose.status_id_destino'],
        ),
        array('table' => 'statuses',
            'alias' => 'Filtro2',
            'type' => 'LEFT',
            'conditions' => ['Filtro2.id = Ose.status_id_destino'],
        ),
        array('table' => 'statuses',
            'alias' => 'Filtro3',
            'type' => 'LEFT',
            'conditions' => ['Filtro3.id = Ose.status_id_destino'],
        ),
    'condition' => array($conditions),
    'order' => array('Ose.id' => 'asc')
);

Above is the alias $conditions and the alias Ose , I do not make their relationship here, since it has already been done in User .

After I hedge the pagination values.

// Aqui é definido quais status serão exibidos
$i = [1, 2, 3];
$this->set(
    'ose', $this->paginate(
        'Ose', array(
            'Ose.ativo' => 't%', 
            'Ose.status_id_destino' => $i
        )
    )
);

Then in Model we do the following:

View

 <?php 
      echo $this->Search->create();
      echo $this->Search->input(
                      'filter1', array(
                            'id' => 'filter1', 
                            'type' => 'hidden'
                       ));
      echo $this->Search->input(
                      'filter2', array(
                            'id' => 'filter2', 
                            'type' => 'hidden'
                       ));
      echo $this->Search->input(
                      'filter3', array(
                            'id' => 'filter3', 
                            'type' => 'hidden'
                       ));
 ?>

And we end with View below where when we click on the desired Snippet , the value is added in the text field sampled in Checkbox , but in fact it will be included in the Snippet field above, as it is done in input .

function filtro1(value) {
  var filter = document.getElementById('filter1');
  if (document.getElementById('1').checked) {
    filter.value = value;
  }
}

function filtro2(value) {
  var filter = document.getElementById('filter2');
  if (document.getElementById('2').checked) {
    filter.value = value;
  }
}

function filtro3(value) {
  var filter = document.getElementById('filter3');
  if (document.getElementById('3').checked) {
    filter.value = value;
  }
}

</table>
