Should a button in a Laravel project trigger methods in the Controller and if so, how

Question

I'm new to Laravel and Web Development in general.

I have an Add to cart button in shop.blade.php :

<a href="{{url('cart')}}" class="btn btn-default add-to-cart"><i class="fa fa-shopping-cart"></i>Add to cart</a>

Then in web.php I have:

Route::get('cart', function()
{
    return View::make('pages.cart', ['active'=>'navCart']);
});

The button obviously redirects to the cart page when pressed.

I'm using LaravelShoppingcart to add items to my cart. To add an item I can use code like:

Cart::add('192ao12', 'Product 1', 1, 9.99);

What I actually want, I think, is some functions, presumably in a Controller (should this be injected into the View?), that I can call from buttons such as Add to cart, decrement "-" or increment "+".

Putting the Cart::add in the Route as shown below is clearly wrong but actually achieves half of what I want - the product is added to the cart (I don't actually want that button to move to the cart page).

Route::get('cart', function()
{
    Cart::add('192ao12', 'Product 1', 1, 9.99);
    return View::make('pages.cart', ['active'=>'navCart']);
});

So, I'm thinking I should be calling methods in the Controller from the View but everyone says I shouldn't do this so what is the proper way to make the View, namely a button, affect the model in Laravel?

Answer 1

Just Define a controller say CartController and in that create function addToCart() and then write the code whatever you want.

like,

class CartController extends Controller
{
    public function addToCart()
    {
    //Your cart related logic
    Cart::add('192ao12', 'Product 1', 1, 9.99);
    return View::make('pages.cart', ['active'=>'navCart']);
    }
}

and then define it in your routes/web.php like,

Route::get('cart', 'CartController@addToCart');
