Magento 1.9 – Save Quote Custom Data and Read It Again

custom-optionsmagento-1.9ordersquote

I store my custom data in my ajax CartController issuing:

foreach ( $quote->getAllItems() as $item ) {
    /* @var $item Mage_Sales_Model_Quote_Item */
    $item->setMyCustomData( 'OK' );
    $item->setOriginalCustomPrice( 777 );
    $item->save();
}

and I want to read these data again in my Order/Pdf/Invoice.php:

foreach ($invoice->getAllItems() as $item){
    Mage::log($item->getOrderItem()->getData()); // Here I wish to see my data set previously
}

The problem is I can only see the price update, but I can not see my MyCustomData field. So I suppose that my custom data stored just as protected _data array don't transfer from quoteItem to orderItem.

How to make it work? Should I rather use some another way to set my custom data?
I thought about product options way, but I don't want to affect all the products, only particular ones.

Thanks.

If you attributes are set up correctly on both the order_item and the quote_item then you maybe missing the xml that copies the attribute value when you save and order.

<fieldsets>
    <sales_convert_quote_item>
        <your_attribute_code>
            <to_order_item>*</to_order_item>
        </your_attribute_code>
    </sales_convert_quote_item>
    <sales_convert_order_item>
        <your_attribute_code>
            <to_quote_item>*</to_quote_item>
        </your_attribute_code>
    </sales_convert_order_item>
</fieldsets>

This will copy the attribute value from quote item to order item when saving the order and also from order item to quote item when recreating a quote from an order via the admin or customer section.

Magento – When to add custom data to quote

Depending on if you need to take cart contents into consideration my suggestion is to put your custom data into quote using either sales_quote_collect_totals_before or checkout_quote_init event.

Then you can observe sales_convert_quote_to_order event and transfer your data from quote to order.

Magento – Difference Between Sales Quote and Sales Quote Address

/app/code/core/Mage/Sales/Model/Quote.php

is the Quote class for the quote object

/app/code/core/Mage/Sales/Model/Quote/Address.php

is the Quote Address class for any quote address objects

A quote object would normally contain 2 address objects, but can contain more if multiple delivery addresses are present.

In regards to the 'collecttotals' method(s): Lets first understand each method, and its purpose:

The method in Mage_Sales_Model_Quote, is the initial entry point for the Totals Collector subsystem, and is initiated by a cart save,

(this allows you to inject class methods into the cart calculations, to affect the outcome of the cart totals - example: calculations of cart discounts)

Code flow as follows:

Mage_Checkout_Model_Cart::save()

Mage_Sales_Model_Quote::collectTotals() <--- entry point of collector subsystem

Mage_Sales_Model_Quote_Address::collectTotals() <-- each address attached to the quote object is called, via a loop in the quote collect totals object.

Now, in the address collecttotals method, a loop is performed, using all the system defined 'collectors', calling each class/method, thus allowing the totals for the order to be adjusted by additional calculations (remember that all totals hang off the address object(s), not the actual quote object, which allows magento to perform checkout to multiple addresses)

foreach ($this->getTotalCollector()->getCollectors() as $model) {
            $model->collect($this);
}

A list of possible 'collectors' would be:

enter image description here

You can inject your own totals collector via a module config as such, and must have a collect method as entry point.

<sales>
   <quote>
      <totals>
         <giftpromo>
           <class>giftpromo/promo_gift</class>
           <after>discount</after>
           <before>tax,grand_total</before>
           <sort_order>12410</sort_order>
         </giftpromo>
      </totals>
    </quote>
</sales>

Now, considering all that information, and the events fired:

sales_quote_collect_totals_before: Gets fired before any address object is loaded, and the totals collector is actioned

sales_quote_address_collect_totals_before: Gets fired inside the quote address object(s), before each address object runs the list of potential collector objects.

Not knowing your end-game, I would not be able to determine which is the right one for you, however, I would also suggest considering if neither is right, and that you'd be best suited with adding in a new collector for the totals collector system

I hope this information helps you determine the right way to extend functionality, and delivery a stable solution.
