How to get data from an observer 'sales_quote_product_add_after'

Question

I have applied this event in my config.xml but I dont know how to get data from this observer. I googled but no article found.

config.xml--

<sales_quote_product_add_after>
    <observers>
        <po>
            <type>singleton</type>
            <class>po/observer</class>
            <method>updateQuote</method>
        </po>
    </observers>
</sales_quote_product_add_after>

Observer file-

public function updateQuote($observer)
{
    Mage::log("testing");
    $quoteItem = $observer->getEvent()->getItems();
    $quote = $quoteItem->getQuote();
    $id = $quote->getId();
    Mage::log($id."hello testing");
}

Getting only "testing" in log file and not getting "hello testing". How can I get info about product added into quote and info of the quote.

Answer 1

This event is written as follow:

Mage::dispatchEvent(‘sales_quote_product_add_after’, array(‘items’ => $items));

Means, we can grab items as follow: $observer->getEvent()->getItems(). And this will be an array of items.

public function updateQuote($observer)
{
    Mage::log("testing", null, 'quote-log.log');
    $items = $observer->getEvent()->getItems();

    foreach($items as $item){
      Mage::log($item->getId()."hello testing", null, 'quote-log.log');

    }
}

Now check file called quote-log.log in your var/log folder.

I haven't tested, but should work.

Try $quoteItem = $observer->getEvent()->getItems() instead of $quoteItem = $observer->getEvent()->getQuoteItem();
