get the values of custom options - magento

Question

I'm trying to alter a price based on some custom options set. Therefore I'm trying to get the value a customer has entered, not the default values set in the backend. To do this I'm using the event catalog_product_get_final_price used in Mage_Bundle_Model_Product_Price. I have registered the following observer:
public function observer_callback($evt_obs)
{
$event = $evt_obs->getEvent();
$data = $event->getData();
/* #var $collection Mage_Catalog_Model_Resource_Product_Collection */
$collection = $data['collection'];
$items = $collection->getItems();
/* #var $item Mage_Catalog_Model_Product */
foreach ($items as $item) {
if ( $item->getName() == 'Bundel Test2') {
$options = $item->getCustomOptions();
/* #var $option Mage_Catalog_Model_Product_Option */
foreach ($options as $option) {
// Here I'm trying to get the value given by the user/customer
var_dump($option->getData());
}
}
}
return $this;
}
It is a custom option from a bundle type. So the product can't be configurable.
I'm new to magento so I'm probably missing something.
Can anyone help me?

Hope this piece of code can help you:
public function productFinalPrice($observer){
$product = $observer->getEvent()->getProduct();
$productType=$product->getTypeID();
if($productType == 'your_product_type')
{
$option = $product->getCustomOptions();
$searchedOption = null;
//search for your option;
foreach ($product->getOptions() as $o) {
if($o->getTitle()=="your_attribute_title" && $o->getType()=="your_type_of_option(eg. area"){
$optionId = $o->getOptionId();//got your searched optionId
break;
}
}
foreach($option as $key => $o) {
if($key == "option_".$optionId) {
$searchedOption = $o;
//here you get the option object with the values in it
}
}
$articleNumber = $searchedOption->getData('value'); // getthe value of your option
//calculate final price like you need it
$product->setFinalPrice($finalPrice);
}
return $this;
}
