Managing the Cart
This page describes some helpful Javascript functions that allow you to manage the cart.
This function replaces the cart in Nosto with the contents of the cart from Shopify and then loads recommendations. This can be useful if you have an Add to Cart button that adds a product to cart via ajax and you want to subsequently show cart-based recommendations.
Nosto.reloadCart()
Nosto supports a quick-buy function straight from within its recommendations. This feature will be referred to as the add-to-cart feature henceforth.
Note: The function definition is a part of the app and is automatically added to all pages. You do not need to define the function or include any additional scripts.
In order to do this, you two arguments must be passed to the
Nosto.addSkuToCart method.The first argument is a javascript object containing the id of the configurable product and the variation, and the second one being the element where the product was added to the cart. If configurable product's id is 123 and the id of the variation is 124 the method call in recommendations template would look like this
Nosto.addSkuToCart({productId: '123', skuId: '124'}, this)
It is possible to specify the quantity when adding products to cart.
Nosto.addSkuToCart({productId: '425', skuId: '310'}, this, 5)
It is also possible to add multiple products to the cart by using an array of objects containing the productId, skuId and quantity. The product id is the parent product that holds the variations, and the SKU is the variation itself. The parent id is needed in order to recognize which product was added and improve the recommendations. Note that if you use a configurable product as SKU ID, will simply not be added to the cart, since you need to select the options.
Nosto.addMultipleProductsToCart(
[
{productId:"1234", skuId:"4321", quantity: 1},
{productId:"345", skuId:"543", quantity: 1}
],
this
)
A common way to implement the functionality to add a variation directly to cart is to implement drop down of available variations for recommended products. The selected variation id is then picked up from the drop down and passed to the
Nosto.addSkuToCart method. An example implementation can be found below.#if($product.skus.size() > 0)
<div class="nosto-sku-select-wrapper">
<label class="nosto-sku-select">
<select onChange="document.getElementById('selected_sku').value = this.value">
<option value="">Choose</option>
#foreach($sku in $product.skus)
<option value="$!sku.id">
#foreach($attr in $sku.customFields)
$!attr.key: $!attr.value
#end
</option>
#end
</select>
</label>
</div>
<button onclick="Nosto.addSkuToCart({productId: '$!product.productId', skuId: document.getElementById('selected_sku').value}, this);return false;" class="nosto-btn">
<img src="$!props.display.buyButtonIcon.url" width="15" height="15">
</button>
#end
Here's an example of how to add an SKU to cart where your product has a single SKU or you want to simply add the product's first SKU to cart instead of allowing the user to select which SKU to add.
<a
href="#"
onclick="window.Nosto.addProductToCart('$!product.lastPathOfProductUrl()', this);">
Add to Cart
</a>
