[TYPO3-commerce] Problems with delivery cost calculation

[Simon Lang]

Hi

I have the same problem. I use the following hook: 
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['commerce/lib/class.tx_commerce_article.php']['calculateDeliveryCost'] 


I made some changes to the commerce code to make it run. Hopefully this 
will be fixed in the future.

To get the weight, just loop over all the articles in the basket and 
count them togheter. I dont know an easier way.

Somethink like that:

$weightAttributeUid = 123; <--- Set the uid of the weight attribute here

//Get the basket
$basket = &$GLOBALS['TSFE']->fe_user->tx_commerce_basket;

//Get all the "normal" articles. No delivery, no payment articles.
$articleUids = 
$basket->get_articles_by_article_type_uid_asUidlist(NORMALArticleType);

$totalWeight
foreach ($articleUids as $articleUid) {
	//Get the basket item. It contains the article.
	$basketItem = $basket->basket_items[$articleUid];

	//Get the article.
	$article = $basketItem->getArticleObj();

	//Get the attribute value.
	$totalWeight+= $article->getAttributeValue($weightAttributeUid);
}

I hope it helps...

Regards
