Question

I have a SectorModel with this function:

public function update(Sector $sector) {
        $this->db->where('sector_id', $sector->getScetor_id());
        return $this->db->update(_SECTOR_, $sector);
} 

There are times that I’ll change only the name of the Sector object:

$Sector = new Sector();
$Sector->setSector_name = 'test';

$this->SectorModel->update($Sector); 

The generated select looks like:

UPDATE realestate_sector SET sector_name = 'teste', sector_description = NULL 

It will update but will set all other properties to NULL because it was not set on my object.
Right now, I have to fill the whole object before sending it.

Is there a way to map the Sector class and update only what was sent on the object?

Thanks in advance for any help.

Sorry for any typos, my English is not good =)

Answer 1

Just loop through all your object’s properites and then if any is NULL just drop it with unset.

Here is your model’s method edited to achieve that:

public function update(Sector $sector)
{
   foreach($sector as $k=>$v)
   {
      if($v === NULL)
         unset($sector->$k)
   }

   $this->db->where('sector_id', $sector->getScetor_id());
   return $this->db->update(_SECTOR_, $sector);
}
