MongoDB Laravel E-commerce #82: Laravel Mini Cart in Header | Minicart Refresh Instantly via Ajax

This is Part 82 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.

In this part, we will make a dynamic mini cart widget at the header of our e-commerce website that will load and update via Ajax every time when a user adds/update or delete products in the shopping cart.

1) Update Helpers File:-
First of all, we will move the getCartItems function from the Cart model to the Helper file so that we can access it anywhere by calling its function without using the model.

4) Update ProductController:-
Now we will update ProductController to update updateCartItemQty and deleteCartItem functions in which we will create headerview to return getCartItems array to display the products via Ajax in mini cart every time when product added/updated or removed in the cart.

Now we will update jQuery functions of updateCartItem and deleteCartitem to return headerview via Ajax success response with id appendHeaderCartItems.
