Yii2 Shopping cart
@todo: upgrade readme, (*1)
Operations with the shopping cart are very straightforward when using a models that implement one of the two cart interfaces.
The cart object can be accessed under \Yii::$app->cart
and can be overridden in configuration if you need to customize it., (*2)
// access the cart from "cart" subcomponent $cart = \Yii::$app->cart; // Product is an AR model implementing CartProductInterface $product = Product::find(1); // add an item to the cart $cart->add($product); // returns the sum of all 'vat' attributes (or return values of getVat()) from all models in the cart. $totalVat = $cart->getAttributeTotal('vat'); // clear the cart $cart->clear(); // render the contents of the cart with default parameters echo \yii2mod\cart\widgets\CartGrid::widget();
Products/items that are added to the cart are serialized/unserialized when saving and loading data from cart storage. If you are using Active Record models as products/discounts, make sure that you are omitting any unnecessary references from the serialized data to keep it compact., (*3)
// get all items from the cart $items = $cart->getItems(); // get only products $items = $cart->getItems(Cart::ITEM_PRODUCT); // loop through cart items foreach ($items as $item) { // access any attribute/method from the model var_dump($item->getAttributes()); // remove an item from the cart by its ID $cart->remove($item->uniqueId) }
