callback_before_update and Amazon API

Hi everybody,

GC saved me a lot of time, I love it a lot.

Now I have a problem with callback_before_update and the amazon api. I searched a lot via google and in this forum, but I didn't find any solutions.

I have in my database table two rows with amazon values: price_new and price_old. I want to receive this values via the amazon api.

For this I have created a function:

public function getAmazonInformation($post_array,$primary_key)
    {
        $amazonerg = $this->amazon_api->getItemByEan($post_array['ean_code']);
        $price_new =  $amazonerg->Items->Item->OfferSummary->LowestNewPrice->FormattedPrice;
        $price_used = $amazonerg->Items->Item->OfferSummary->LowestUsedPrice->FormattedPrice;


        $post_array["price_amazon_new"] = $price_new;
        $post_array["price_amazon_used"] = $price_used;

        return $post_array;
    }

My CRUD Function looks like:

public function item()
    {
        $crud = new grocery_CRUD();
       
        $crud->set_theme('datatables');
        $crud->set_table('item');
        $crud->set_subject('Item');

        $crud->columns('main_media','model','price','filter','power_watt','noise_level');

        $crud->set_relation('manufacturer_id','manufacturer','name');
        
        $crud->set_field_upload('main_media','assets/uploads/');
        $crud->callback_before_update(array($this, 'getAmazonInformation'));

        $crud->callback_after_upload(array($this,'thumbnailer'));

        $crud->unset_texteditor('teaser');
        $crud->unset_read();

        $output = $crud->render();
        $this->_example_output($output);
    }

It doesn't works and I dont know why. When I call the function getAmazonInformation direct, everything works fine. The values are right, but via the callback function nothing happens and the values aren't available.

Thank you for your support!
