Magento getSingleton() vs getModel() issue

Question

I want to loop over an array of product IDs in Magento. In the loop I am displaying some custom attributes of the products as:

foreach ($products as $product         


        

Answer 1

You´ll find the difference between getModel() and getSingleton() in the other answers.

But if you want to speed up your code, assuming you have a collection, do the following:

$products->addAttributeToSelect('credits');

foreach ($products as $product) {
   echo '
' . $product->getCredits();
}

So you don´t have to load every product, which is very time-consuming.
