[TYPO3-commerce] Show scaled prices in basket & redirect to previous page after buying article

In the basket, you should always see the correctly scaled price - if 
not, something is wrong. It at least works in my installation, and I 
also only use net prices (b2b-shop), but I tweaked quite a lot for a 
better handling of only net prices.

For the scaled prices in the detail view - I coded a little snippet for 
one of the marker hooks:
----
Hook:
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['commerce/lib/class.tx_commerce_pibase.php']['articleMarker']
----
  	function additionalMarkerArticle($markerArray,&$article,&$parent) {
  		$data = &$article->returnAssocArray();
  		$piVars = &$parent->piVars;
  		
  		// scaled prices - but for now only in singleView
  		$markerArray['ARTICLE_SCALE_PRICES'] = '';
  		if($piVars['showUid']) {
  			$scaledPrices = $article->getPriceScaleObjects(2);
  			if(is_array($scaledPrices) && count($scaledPrices)) {
  				$scaleMarker = array();
  				$scaleTemplateTotal = 
$parent->cObj->getSubpart($parent->templateCode,'###SCALED_PRICES###');
  				$scaleTemplateItem = 
$parent->cObj->getSubpart($scaleTemplateTotal,'###SCALED_PRICE_ITEM###');
  				foreach($scaledPrices as $startValue => $array) {
  					$priceObject = current($array);
  					$scaleMarker['###SCALE_START###'] = intval($startValue);
  					$scaleMarker['###SCALE_END###'] = intval(key($array));
  					$scaleMarker['###SCALE_PRICE_NET###'] = 
tx_moneylib::format($priceObject->get_price_net(),$parent->currency);
  					$scaleMarker['###SCALE_PRICE_GROSS###'] = 
tx_moneylib::format($priceObject->get_price_gross(),$parent->currency);
  					$scaleItems[$startValue] = 
$parent->cObj->substituteMarkerArrayCached($scaleTemplateItem,$scaleMarker);
  				}
  				ksort($scaleItems);
  				$scaleSubpartArray['###SCALED_PRICE_ITEM###'] = 
implode('',$scaleItems);
  				$markerArray['ARTICLE_SCALE_PRICES'] = 
$parent->cObj->substituteMarkerArrayCached($scaleTemplateTotal,array(),$scaleSubpartArray);
  			}
  		}
  		return $markerArray;
  	}

I'm not aware of such a functionality, but you can use one of the hooks 
for that. But not 'postartAddUid', because not all basket handling is 
finished on that point and the basket isn't stored yet. Maybe you can 
use 
'$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['commerce/pi2/class.tx_commerce_pi2.php']['generateBasketMarker']' 
for it - although it causes some overhead because of the marker processing.


Hope that helps.
