$product->getDisableAddToCart() magic method questions

Question

I've run into an issue where $product->getDisableAddToCart() is returning bool(true) for some products, but I can't find a declaration of that method, nor can I find an attribute disable_add_to_cart in eav_attributes.

The method is called in

• app\code\core\Mage\Wishlist\Controller\Abstract.php line 103
• app\code\core\Enterprise\CatalogPermissions\Model\Observer.php line 323, 380, 540 (Enterprise 1.14.0.1)
• app\code\core\Enterprise\Checkout\Model\Cart.php line 1021 (Enterprise 1.14.0.1)

Can anyone tell me where this is defined?

Answer 1

It turns out that this is being set with a Magic Setter, so no actual method or attribute even exists. Just search the codebase for $product->setDisableAddToCart() to find all of the places where it is called.

Answer 2

You can check the event in app/code/core/Enterprise/CatalogPermissions/etc/config.xml

Event: checkout_cart_save_before : enterprise_catalogpermissions

Function name:

1. checkQuotePermissions()
2. _initPermissionsOnQuoteItems($quote) - Just can see the line: $item->setDisableAddToCart(true);

Which will reflect to this line: $quote->removeItem($quoteItem->getId());
