MongoDB Laravel | Make E-commerce #79: Shopping Cart (IV) | Conditions to Check While Updating Cart

This is Part 79 of the Laravel 11 Tutorial in which we are building the e-commerce website with Laravel as the front end and MongoDB as the back end. We will continue working on the Laravel shopping cart page where we will show cart items.

In this part, we will add conditions to check whether product stock is available or not. We will show an error message if product stock is not available via Ajax.

1) Update updateCartItemQty function :-
First of all, update the updateCartItemQty function to check whether the stock demanded by the user in the cart is available in the products attributes table or not.

Now update the jQuery function to get the status and alert the error message "Product Stock is not available" in case the status is false.

3) Update updateCartItemQty function :-
We can update the updateCartItemQty function to add the size available check as well.

In the next part, we will work on the delete cart item functionality via Ajax.
