Hello!

I am developing a miniframework, for my projects, and tbm create more knowledge about object orientation in PHP

I created a MODEL where it is a big part of everything, and my classes extend this MODEL.... So far virtually everything is working, update, delete, update, findAll, findAllByPk, Findallbyattributes etc.

But what I wanted to do now is class relations. Ex:I have a class Product and a Category, where every product has a category.

At the time of showing this in the view, I wanted to call as follows:

$Product->Category->attribute_category

but so far I am unsuccessful, I thank anyone who can help me (gives me a north) of how to do this.

What I would do if I were you would be the following:

class Produto
{

  protected $objCategoria; //faça get's end seter's
  protected $idCategoria;  //faça get's end seter's
  ...

  protected function getCategoriaProduto($idCategoria){
     $this->$categoria = new Categoria($idCategoria);
  }

  public function getProduto($idProduto){
    //processamento para pegar produto
    $this->getCategoriaProduto($this->$idCategoria);  
  }
}

What I did was create an objCategory property, which stores an object of the category class (which has to be defined by you), when you do a product search through a getProduct method, for example. Such a method creates an instance of the Category class, which feeds the objCategory property.

to better fit in with what you have already done, you can feed $objCategoria with a findAllByPk of the Category class, within your findAllByPk method of the Product Class.
