php - How to handle multiple-currency and custom quote item price on Magento? -

i have magento store 2 currency, , items in cart have dynamic price. succesfully calculate quote_item price, observer , setcustomprice , setoriginalcustom price

 $quote_item->setcustomprice($price);  $quote_item->setoriginalcustomprice($price); 

and observer:

<sales_quote_add_item> 

but have problem, when change currency of store, subtotal not update. how handle multiple-currency , custom quote item price ?

i've had same issue on last week. using ->setoriginalcustomprice method fine single currency site, currency switching, rigidness means need update cart items , list price everytime currency switched, inefficient in opinion.

i came more elegant solution. create module , within model section of config add this;

<models>         <catalog>             <rewrite>                 <product>pixiemedia_customprice_model_product</product>             </rewrite>         </catalog> </models> 

counter intuitively, main ->getfinalprice function in product model , not price model.

now create new product.php model in /app/code/local/namespace/module/model/product.php

class pixiemedia_customprice_model_product extends mage_catalog_model_product {  public function getfinalprice($qty=null) // rewritten function return special price , ensure currency conversion {     $qbreak = false;     $customprice = mage::helper('pixiemedia_customprice')->getcustomerprice($this);      if($qty) {          $qbreak = $this->getqtybreakprice($this->getsku(),$qty,$customprice[0]);          }      if($qbreak) { return $qbreak; } else { return $customprice[0]; }  }  } 

on particular project working on, client using multiple price lists customer specific pricing, scope of make magento horrendously slow index pricing. we've loaded data custom table , perform lookup return customer's correct price or qty break.

it's dead easy hook own logic in , return ever price wish. supports currency conversion, no need fiddle around re-converting prices.

hope helps out. enjoy :)
