Magento – Update store product prices on catalog_product_save_before

event-observerpriceproduct

On catalog_product_save_before event I've got handler that should update prices for product. On save I need to update prices for every store, not one price for Default.

$sellerslist = Mage::getModel('mpassignproduct/mpassignproduct')->getCollection();
$sellerslist = $this->getSellersList();
$data = $sellerslist->getData();
if (!empty($data) && count($data) > 0 && !empty($data[0]['mpassignproduct_id']) && $data[0]['mpassignproduct_id'] + 0 > 0) {
    $stores = Mage::helper('advox_core')->getStoresByWebsiteId($websiteId);
    foreach ($stores as $storeId) {
        // Previously I tried to load this product to new variable.
        //$product = Mage::getModel('catalog/product')->setStoreId($storeId + 0)->load($product->getId());
        $product->setStoreId($storeId + 0);
        $product->setMinPrice($data[0]['minprice']);
        $price = $data[0]['minprice'];
        if ($price === null) {
            $price = 0;
        }
        $product->setPrice($price);
    }
}

I can't load product again for specific store because on save there is once again called catalog_product_save_before so infinite event observer is called.
How to change product prices for specific store.

Update:

I changed to:

$websiteIds = $product->getWebsiteIds();
foreach ($websiteIds as $websiteId) {
    $sellerslist = $this->getSellersList();
    $data = $sellerslist->getData();
    if (!empty($data) && count($data) > 0 && !empty($data[0]['mpassignproduct_id']) && $data[0]['mpassignproduct_id'] + 0 > 0) {
        $product->setWebsiteId(array($websiteId + 0));
        $product->setMinPrice($data[0]['minprice']);
        $price = $data[0]['minprice'];
        if ($price === null) {
            $price = 0;
        }
        $product->setPrice($price);
    }
}
$product->setWebsiteIds($websiteIds);

as you said that prices should be changed only for websites. I tried with catalog_product_prepare_save event but still not updating.

Update 2:

While saving product in admin panel I've got only global product model. Is there any simple way to load website specific data to this product model and then change this details?

You usually would do something like that with an observer on catalog_product_prepare_save, this event is triggered in Mage_Adminhtml_Catalog_ProductController::_initProductSave().

But you cannot set prices per store, prices can only be set per website. Changing the allowed scope of the price attributes would require significant changes in the core, especially the price index. So if you need different prices on different sites, create separate websites, not only separate stores.
