Auto generation of meta description

Question

i want auto generation of meta description for my products liks this: Buy {product name} for Rs {price} at sitename.com | New Book | Authorised seller for {publihser}

Answer 1

Just create an observer on the event catalog_product_save_before with this code:

public function autoMetaDescription($observer) {
     $product = $observer->getEvent()->getProduct();
     $metaDescription = "Buy ". $product->getName()." for Rs ".number_format($product->getFinalPrice(), 2)." at sitename.com | New Book | Authorised seller for ". $product->getAttributeText('publisher');
    $product->setMetaDescription($metaDescription);
} 

Of course you may need some changes if the website is multilanguage. You have to check on which language you are saving the product.
