The HTML Markup

The HTML has two parts, product list and cart list. The product list can be any design you prefer, Smart Cart will not managed it, but there is some setting need to do so that Smart Cart can identify the "Add To Cart" buttons and the values of the product. While the cart list is fully managed by Smart Cart ofcourse it is customizable too.

First we can look at the basic of the product list
Things to note:

  • Add to cart button is identified by searching for the elments with class name "sc-add-to-cart", and a click event is attached with it.
  • Then the product container of a product is identified by the class name "sc-product-item"
  • The product container must have the basic values for the product like product_name, product_price etc
  • The product values like product_price is identified by searching for an element with attribute name or data-name
  • All the element values with attribute name or data-name will be added to product object
<div class="row">
<!-- BEGIN PRODUCTS --> <div class="col-md-4 col-sm-6">
<!-- PRODUCT CONTAINER 1, identified by the class "sc-product-item" --> <div class="sc-product-item">
<!-- PRODUCT IMAGE, identified by data-name="product_image" --> <img data-name="product_image" src="" alt="...">
<!-- PRODUCT NAME, identified by data-name="product_name" or can be an element with name="product_name"--> <h4 data-name="product_name">Product 1</h4>
<!-- PRODUCT DESCRIPTION, identified by data-name="product_desc" or can be an element with name="product_desc"--> <p data-name="product_desc">Product details</p>
<!-- PRODUCT PRICE, identified by name="product_price" or can be an element with data-name="product_price"--> <input name="product_price" value="2990.50" type="hidden" />
<!-- PRODUCT ID, identified by name="product_id" or can be an element with data-name="product_id"--> <input name="product_id" value="12" type="hidden" />
<!-- ADD TO CART BUTTON, identified by class="sc-add-to-cart" --> <button class="sc-add-to-cart btn btn-success">Add to cart</button>
</div> <!-- END PRODUCT CONTAINER 1 --> </div>
<div class="col-md-4 col-sm-6">
<!-- PRODUCT CONTAINER 2 --> <div class="sc-product-item"> <img data-name="product_image" src="" alt="..."> <h4 data-name="product_name">Product 2</h4> <p data-name="product_desc">Product details</p> <input name="product_price" value="320.75" type="hidden" /> <input name="product_id" value="14" type="hidden" /> <button class="sc-add-to-cart btn btn-success">Add to cart</button> </div> </div> <!-- END PRODUCTS --> </div>

And the second part is the cart HTML which is simple. A div element wrapped with a form element which we can used to submit the cart values

<form action="results.php" method="POST"> 
<!-- SmartCart element --> <div id="smartcart"></div>
