How to update an object in Zend Framework 2 - zend-framework

Question

i'm trying to update an object by using this code :
The column co_nbre will be updated to 0 !!!!
I think you will help me to fix this issue and thnx a lot.
public function update($model) {
$data = get_object_vars($model);
$id = (int) $model->id;
$this->tableGateway->update($data, array('id' => $id));
}
and this is how did i use it in my controller:
if ($form->isValid()) {
$data = $form->getData();
$addi_info = new Addiinfo();
$addi_info->exchangeArray($data);
$addi_info->co_nbre = $request->getPost("co_nbre");
$addi_info->user_pin = $this->layout()->pin;
$addi_info->co_latitude = $request->getPost("latitude");
$addi_info->co_longitude = $request->getPost("longitude");
$addi_info->co_adresse = $request->getPost("adresse");
print_r($addi_info);die;
$checkuser=$this->getAddiinfoTable()->getAddiInfoByUserPin($user_pin);
if($checkuser[user_pin]==$user_pin){
$this->getAddiinfoTable()->update($addi_info);

Answer 1

I think you should create a function that returns associative array from model itself.
May be some of property in "Addiinfo" class be protected/private, so you need to get all property-value of model from inside it.
This one should be in your "Addiinfo" class,
public function getArrayData()
{
return get_object_vars($this);
}
Then call it in update function
public function update($model) {
$data = $model->getArrayData();
$id = (int) $model->id;
$this->tableGateway->update($data, array('id' => $id));
}
