Creating a bundled product with Magento - magento

Question

I've been following along with this example: Magento programmaticaly create bundle Product
and the code is working when I create a new product, however, I can't get it to work when I load a product either bundled or simple. [EDIT] I can load a bundled product that I created programmatically through the code below and add products to the bundle. A bundled product I created through the GUI I cannot add products too.
Any idea how I can load a product up then bundle it with another a product?
Here is my current code:
$items = array();
$items[] = array(
'title' => 'Bundle Option',
'option_id' => '',
'delete' => '',
'type' => 'radio',
'required' => 1,
'position' => 0,
);
$selectionRawData = array();
$selectionRawData[0] = array();
$selectionRawData[0][] = array(
'selection_id' => '',
'option_id' => '',
'product_id' => 3,
'delete' => '',
'selection_price_value' => 0,
'selection_price_type' => 0,
'selection_qty' => 1,
'selection_can_change_qty' => 0,
'position' => 0,
'is_default' => 1,
);
$selections = $selectionRawData;
$websiteIDs = array(1);
$cats = array(4);
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
// load product
// NOT WORKING
$product = Mage::getModel('catalog/product');
$product->load(127);
// new product
/******
* THIS WORKS
$p = array(
'sku_type' => 1,
'sku' => '123321',
'name' => "BarProduct",
'description' => 'Foo',
'short_description' => 'Bar',
'type_id' => 'bundle',
'attribute_set_id' => 4,
'weight_type' => 0,
'visibility' => 4,
'price_type' => 1,
'price_view' => 0,
'price' => 1.99,
'has_options' => 1,
'required_options' => 1,
'status' => 1,
'created_at' => strtotime('now'),
'category_ids' => $cats,
'store_id' => 0,
'website_ids' => $websiteIDs,
'weight' => 0,
'weight_type' => 1,
'delivery_time' => '',
'generate_meta' => 1,
'tax_class_id' => 1, //19%
);
$product->setData($p);
*****/
Mage::register('product', $product);
Mage::register('current_product', $product);
$product->setCanSaveConfigurableAttributes(false);
$product->setCanSaveCustomOptions(true);
$product->setBundleOptionsData($items);
$product->setBundleSelectionsData($selections);
$product->setCanSaveCustomOptions(true);
$product->setCanSaveBundleSelections(true);
$product->setAffectBundleProductSelections(true);
$product->save();
$result['product_name'] = $product->getId();
return $result;

Answer 1

This is important for bundled products:
$product->setData("price_type", 0);
You must set this attribute to 0 (Dynamic price) before saving.
Reindexing is then necessary of course.

Answer 2

I had some funky stuff going on with my product index. I deleted all my products and fixed my index and this now works, albeit not well.
So here is what I gleaned from the process:
If you want to take two simple products and bundle them, you'll need to create a new bundled bundled product via the $p = array code above, then add both simple products.
Otherwise, you'll need a bundled product that is premade via the magento gui. then you'll have bring up that product using the $product->load(product_id) command, then add your simple products to that.

Answer 3

Just delete all unneeded options like this:
$optionsselectionsmap = array();
$options = Mage::getModel("bundle/option")->getCollection()->setProductIdFilter($product->getId());
foreach($options as $option){
$selection = Mage::getModel("bundle/selection")->getCollection()->setOptionIdsFilter($option->getId())->getFirstItem();
$tmp = array();
$tmp['option_id'] = $option->getId();
$tmp['selection_id'] = $selection->getData('selection_id');
$optionsselectionsmap[$selection->getData('sku')] = $tmp;
}
$deleteoptionids = array();
foreach($optionsselectionsmap as $k=>$v) $deleteoptionids[] = $v['option_id'];
foreach($product->getTypeInstance(true)->getOptionsCollection($product) as $deleteitem){
$deleteitem = $deleteitem->getData();
$deleteitem['delete'] = 1;
$bundleOptions[] = $deleteitem;
}
