How to update multiple fields on one row with CakePHP - mysql

Question

I'm trying to update multiple fields of a row on a table on the database. I tried several solutions I found here in stackoverflow but no one had worked for me.
In this function, I give a feedback of a 'Product', and in the table Product I have 4 fields, called num_votes, num_negative_votes, num_neutral_votes and num_positive_votes.
When I call this function, i need to update this fields of the database depending on the value of the form.
How can I update 2 fields at the same time?
The solution I tried is this one: CakePHP - How to update multiple records
public function setFeedback($id = null) {
$this->autoRender = false;
if (!$id) {
$this->redirect(array('action' => 'index'));
}
else {
$product = $this->Product->findById($id);
$num_votes = $product['Product']['num_votes'] + 1;
if($this->request->data['Product']['num_points'] == "0") {
$num_negative_votes = $product['Product']['num_negative_votes'] + 1;
$arrayToSave = array(
'num_votes' => $num_votes,
'num_negative_votes' => $num_negative_votes);
$this->Product->saveMany($arrayToSave, array('deep' => true));
}
else if ($this->request->data == "1") {
$num_neutral_votes = $product['Product']['num_neutral_votes'] + 1;
$arrayToSave = array(
'num_votes' => $num_votes,
'num_neutral_votes' => $num_neutral_votes);
$this->Product->saveMany($arrayToSave, array('deep' => true));
}
else if ($this->request->data == "2 ") {
$num_positive_votes = $product['Product']['num_positive_votes'] + 1;
$arrayToSave = array(
'num_votes' => $num_votes,
'num_positive_votes' => $num_positive_votes);
$this->Product->saveMany($arrayToSave, array('deep' => true));
}
$this->redirect(array('action' => 'index'));
}
}

Try this-
public function setFeedback($id = null) {
$this->autoRender = false;
if (!$id) {
$this->redirect(array('action' => 'index'));
}
$product = $this->Product->findById($id);
$num_votes = $product['Product']['num_votes'] + 1;
if($this->request->data['Product']['num_points'] == "0") {
$num_negative_votes = $product['Product']['num_negative_votes'] + 1;
$arrayToSave['Product']['num_negative_votes'] = $num_negative_votes;
}
else if ($this->request->data == "1") {
$num_neutral_votes = $product['Product']['num_neutral_votes'] + 1;
$arrayToSave['Product']['num_neutral_votes'] = $num_neutral_votes;
}
else if ($this->request->data == "2 ") {
$num_positive_votes = $product['Product']['num_positive_votes'] + 1;
$arrayToSave['Product']['num_positive_votes'] = $num_positive_votes;
}
$arrayToSave['Product']['num_votes'] = $num_votes;
$this->Product->id = $id;
if($this->Product->save($arrayToSave)){
$this->redirect(array('action' => 'index'));
}else{
$this->Session->setFlash('Something is wrong.');
}
}
