custom script specific store

[agiorgini]

Hi,

I've made a script to set meta title and meta description for a specific storage, with data coming from a csv. They got actually saved, but the odd thing is other fields (seems like random) got the "Use default" flag unset.

Why is this?

Here is excerpt of my script:

if (($handle = fopen($src, "r")) !== FALSE) {
        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {

            if ($data[0] == 'sku')
                continue;

            $sku = trim($data[0]);
            $**bleep** = trim($data[1]);
            $desc = trim($data[2]);

            if ($sku != '') {
                $product = Mage::getModel('catalog/product')->loadByAttribute('sku', $sku);

                if (!is_object($product) || !$product->getEntityId()) {
                    echo "\nNon trovo il prodotto: $sku\n";
                    continue;
                }

                $product->setStoreId(4)->load($product->getId())->setMetaTitle($**bleep**)->setMetaDescription($desc);

                try {
                    $product->save();
                    $i++;
                } catch (Exception $ex) {
                    die($ex->getMessage());
                }

            }
        }
    }

thanks a lot

UPDATE:

if I replace

product->setStoreId(4)->load($product->getId())->setMetaTitle($**bleep**)->setMetaDescription($desc);

with

$product->setStoreId(4)->setData('meta_title', $**bleep**)->setData('meta_description', $desc);

I really would love to know why is this.

Thanks
