Make model classes more extension friendly

I also posted it on GitHub, not sure whether it was the right place or not, hence I post it here, too.

It would be nice if the model classes could be made more extension friendly.
Sometimes 3rd party addons introduce new DB fields in e.g. the 'category', 'product'
or other DB tables.

If the add methods, such as the function 'addCategory' in 'admin/model/catalog/category.php'
were to return the primary key value, e.g. 'category_id', then an extended model class
could simply add its own additional field values like this:

Code: Select all

// example of an overridden method in an extended model class
public function addCategory($data) {
  $category_id = parent::addCategory($data);
  $sql = "UPDATE ".DB_PREFIX."category SET newfield = '".$data['newfield']."' WHERE category_id = '".(int)$category_id."'";
  $this->db->query($sql);
  return $category_id;
}
