Question

I am creating a module that takes an SKU via a GET requests and returns a JSON object with some of that product’s attributes.

My indexController function code looks like this

public function pinboardgetitemsAction(){
    $sku = $_GET[sku];

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

    $fullItem = array();

    $fullItem[0] = $product->getName();
    $fullItem[1] = $product->getFormatedPrice();
    $fullItem[2] = $product->getSmallImageUrl();

    echo json_encode($fullItem);

}

When I load this request in a browser it correctly returns the JSON object

However when I do an AJAX request (I am using jQuery) $sku is not set and an Fatal error is thrown.

The easiest way to see this behaviour is by using http://hurl.it

Aside from my typo comment, the appropriate way to access params is through the request object:

$sku = $this->getRequest()->getParam('sku');
