🔹Cart Layouts

How to customise the Shopping Cart Layout

Prerequisites

đŸŒŗ Folder Structure

Cart layouts are stored in the following structure:

marketplace_builder
└───views
    └───partials
        └───layouts
            └───modules
                └───module_14
                    └───product
                        collection.liquid
                        └───custom_cart_layout
                            └───list
                                item.liquid
                                wrapper.liquid

See the full Cart & Checkout folder structure here:

đŸŒŗCart and Checkout Folder Structure

wrapper.liquid

The wrapper.liquid file should contain the code for the main section of code that wraps around the loop of Products in the Cart. It should include the following liquid to insert the loop of Products:

{% assign cart_parsed = context.session.cart | parse_json %}
{% if cart_parsed.size > 0 %}
  {%- include 'modules/siteglide_ecommerce/ecommerce/get/get_products' item_layout: 'item' -%}
{% else %}
  Sorry, your cart is empty.
{% endif %}

Empty the Cart

<button onclick="s_e_cart_empty(true)">Empty Cart</button>

Of course, this is just an ordinary link. It will need updating with the slug of your Checkout Page: <a href="/checkout>Proceed to checkout</a>

Reference

The following reference shows how to output useful data about your Cart as a whole:

Field Name
Liquid Tag

Total Quantity

{{context.exports.cart_total_quantity.data}}

Shipping Price

Shipping Price Before Tax

Shipping Price Tax Amount

Total Item Price

Total Item Price before Tax

Total Item Tax Amount

Total Price Reduction (due to discounts)

Final Total Price before Tax

Final Total Tax Amount

Final Total Price

If you have added Product Attributes to the Products in the Siteglide Admin, you can also access the cart_product_attributes with the following liquid: {{ context.exports.cart_product_attributes }}

Normally though, Attributes will be handled in the next step- the item.liquid file.

item.liquid

The cart layout will iterate in a loop, outputting the item.liquid file for each line in the customer's cart.

cart_id

Each line in the cart has a cart_id accessible at {{this.cart_data.cart_id}}. When modifying the cart with JS, this cart_id will be needed. Multiple lines in the cart may refer to the same product if a different combination of attributes is selected.

Building the Cart's item.liquid file is similar to building an item.liquid layout file for a Product List View. Learn more about the available fields here.

There are some additional points to bear in mind when creating a cart layout's item.liquid file:

Removing an individual Product from the Cart:

The s_e_cart_remove function can be used to remove a line from the cart.

If the cart has several lines containing the same product, but with different attributes, only the targeted line and its attributes will be removed.

In this example, the function is called when a button is clicked and Liquid is used to pass the cart ID into the function:

item.liquid

<button onclick="s_e_cart_remove(true,{{this.cart_data.cart_id}})">
  Remove Item from Cart
</button>

You can optionally pass in a callback function to the third argument to be called after the row has been removed from the cart. In order for this to work, you need to set reload (the first argument) to false.

item.liquid

<button onclick="s_e_cart_remove(false,{{this.cart_data.cart_id}},removeCallback)">
  Remove Item from Cart
</button>

JavaScript

function removeCallback() {
  //Do something
}

Increasing the Quantity of a Product in the Cart:

See the full Article on updating Product quantities here.

item.liquid

<!-- Step 1 -->

<input 
  type="number"
  name="quantity"
  min="1"
  value="{{this.cart.data.quantity}}"
  onchange="s_e_cart_update_quantity(event.target.value,{{this.cart_data.cart_id}},'{{context.authenticity_token}}',false)"
>

wrapper.liquid

<!-- Step 2 -->

<button onclick="s_e_cart_update(false,'{{context.authenticity_token}}')">Update Cart</button>

Note that, after updating this input field, the User will also have to click the "Update Cart" button. Following the link above will lead to a more detailed article.

Outputting the Attributes the User chose for this item:

{% include 'ecommerce/cart_product_attributes' %}

Controlling Inventory

In order to make sure Users do not increase the quantity of items in their Cart, when the Product is out of stock, you could add a "max" attribute to the quantity input:

<input type="number" 
       name="quantity" 
       min="1" 
       max="{{this.inventory.quantity}}" 
       value="{{this.cart_data.quantity}}" 
       onchange="s_e_cart_update_quantity(event.target.value,{{this.cart_data.cart_id}},'{{context.authenticity_token}}')"
/>

Items added to a Cart in Siteglide are not reserved. It is possible for two or more customers to add the last product in stock to their cart at once.
