Dynamic checkbox and get the values from the checkbox checked - php

Question

I am having difficulty creating dynamic checkboxes from db, and getting the values from the checkboxes when checked.
I have this Controller:
public function proporEvento(){
$natureza = $this->evento_model->naturezaEvento();
$apoio = $this->evento_model->apoioPertendido();
$espaco = $this->evento_model->espaco();
$material = $this->evento_model->material();
$suportgraf = $this->evento_model->suporteGrafico();
$audiovisual = $this->evento_model->audioVisual();
$data['title'] = 'Propor Evento';
$data['naturezaEvento'] = $natureza;
$data['apoioPertendido'] = $apoio;
$data['espaco'] = $espaco;
$data['material'] = $material;
$data['suporteGraf'] = $suportgraf;
$data['audioVisual'] = $audiovisual;
$this->load->view('cliente/clienteheaderdash_view', $data);
$this->load->view('cliente/clientemenu_view', $data);
$this->load->view('cliente/clienteproporevento_view', $data);
$this->load->view('cliente/clientefooterdash_view', $data);
}
Have this model:
public function naturezaEvento(){
$query = $this->db->get('tblnaturezaevento');
return $query->result();
}
public function apoioPertendido(){
$query = $this->db->get('tblapoio');
return $query->result();
}
public function espaco(){
$query = $this->db->get('tblespaco');
return $query->result();
}
public function material(){
$query = $this->db->get('tblmaterial');
return $query->result();
}
public function suporteGrafico(){
$query = $this->db->get('tblsuportegraf');
return $query->result();
}
public function audioVisual(){
$query = $this->db->get('tblaudiovisual');
return $query->result();
}
...and I have this view (one part for example):
<label>Apoio Pertendido</label>
<div class="form-group">
<?php foreach ($apoioPertendido as $row) { ?>
<label>
<input type="checkbox" class="flat-red" name="apoiopretendido[]" value="<?php echo $row->idApoio ?>" /> <?php echo $row->descricao; ?>
</label>
</br>
<?php } ?>
</div>
this code create the <input type="checkbox"...> correctly but how can I get the values from checked checkbox?
My form to go with this controller function:
public function etapa2(){
//$this->load->library('form_validation');
// $this->form_validation->set_rules('naturezaEvento', 'naturezaEvento', '|required|');
//$this->form_validation->set_rules('denominacao', 'denominacao', '|required|');
// $this->form_validation->set_rules('datainicio', 'datainicio', '|required|');

// $this->form_validation->set_rules('datainicio', 'datainicio', '|required|');
