Hi,

I have a problem when trying to update data in my MySQL DataBase, the update method look like :

Code:

function UpdateUser($option=array()){     //required data
if(!$this->_required(array('F_IMGH_USER_ID'), $options
)) return false;
    
if(isset($option['F_IMGH_USER_NAME']))    $this->db->set('F_IMGH_USER_NAME',$option['F_IMGH_USER_NAME']);
  
if(isset($option['F_IMGH_USER_PNAME']))    $this->db->set('F_IMGH_USER_PNAME',$option['F_IMGH_USER_PNAME']);
  
if(isset($option['F_IMGH_USER_DAT_NAISS']))
$this->db->set('F_IMGH_USER_DAT_NAISS',$option['F_IMGH_USER_DAT_NAISS']);
  
if(isset($option['F_IMGH_USER_EMAIL']))
$this->db->set('F_IMGH_USER_EMAIL',$option['F_IMGH_USER_EMAIL']);
  
if(isset($option['F_IMGH_USER_LOGIN']))
$this->db->set('F_IMGH_USER_LOGIN',$option['F_IMGH_USER_LOGIN']);
  
if(isset($option['F_IMGH_USER_PASSWORD']))
$this->db->set('F_IMGH_USER_PASSWORD',$option['F_IMGH_USER_PASSWORD']);
  
if(isset($option['F_IMGH_USER_ACTIVE']))
$this->db->set('F_IMGH_USER_ACTIVE',$option['F_IMGH_USER_ACTIVE']);
  
if(isset($option['F_IMGH_USER_LEVEL']))
$this->db->set('F_IMGH_USER_LEVEL',$option['F_IMGH_USER_LEVEL']);
  
if(isset($option['F_IMGH_USER_LAST_LOGIN']))
$this->db->set('F_IMGH_USER_LAST_LOGIN',$option['F_IMGH_USER_LAST_LOGIN']);
  
$this->db->where('F_IMGH_USER_ID',$option['F_IMGH_USER_ID']);
  
$this->db->update('fimgusers');
  
return $this->db->affected_rows();
  
}

and in the login method of the user model, i do :

Code:

...
if($this->UpdateUser($data)){
   return true;
}else{
   return false;
}
...

but when i run my application nothing hapend! thhe login method is called but it return false and the update process is never done!!

Can some one help me to fix this
