get invoice id from a Mage_Sales_Model_Order_Invoice object

Question

I'm writing an observer for the sales_order_invoice_register event, I'd like to get the invoice number that has just saved. I can't find the function for retrieving that ID, none of those commented calls works. Any idea? Here the code

public function foobar($observer){

      $order = $observer->getEvent()->getOrder();
      $id_order = $order->getRealOrderId();
      $id_invoice = $observer->getEvent()->getInvoice(); // the Mage_Sales_Model_Order_Invoice object
      //$id_invoice = $id_invoice->getId();                                                                                                         
      //$id_invoice = $id_invoice->getIncrementId();                                                                                                            
      //$id_invoice = $id_invoice->getInvoiceId();                                                                                                           
      //$id_invoice = $id_invoice->getRealIncrementId();                                                                                               
      //$id_invoice = $id_invoice->getData('invoice_id');

thanks!

Have you tried a `var_dump($id_invoice->getData());` to see if it gives anything helpful? — jprofitt, Nov 04 '11 at 14:28
[no there isn't anything useful](http://pastebin.com/XhpZ81Ms) :( — Infrid, Nov 04 '11 at 14:55
I just took a quick peak at the Invoice model, and it's possible that the object hasn't been saved yet when that event is called so it doesn't have an ID. What were you needing the ID for? Maybe I can help figure out a work around. — jprofitt, Nov 04 '11 at 15:10
I just need the order and the invoice id for bureaucracy reasons. The action should be fired immediately after the invoice has been created. I'm trying different event name now... — Infrid, Nov 04 '11 at 15:34

I know this was a while ago, but in case someone still needs help on this, hopefully the following will be of use.

Once in your observer method, use the following code to get invoice ID.

$invoice = $observer->getEvent()->getInvoice();
$invoice_id = $invoice->getData('entity_id');  // or you could also use ->getEntityId();

You can check out the sales_flat_invoice table in the Mage db (ID is the first field with the name 'entity_id'). Once you have the $invoice object, similar to any other object that inherits from the Varien_Object class, you can use Magento's getData() method to access attribute values.

Also, need to look at a different event possibly... the sales_order_invoice_register event returns "unknown" according to Mage docs. Try the sales_order_invoice_pay event for the above code.

You should use the event "sales_order_invoice_save_after" in the config.xml and in your observer.php : $observer->getEvent()->getInvoice();
