Can't use "View::Share" to display items cart count

[christophe-44-27]

Hi,
I would like to display the number of items from my cart, into my navigation bar. I want to use AppServiceProvider to facilitate my work but something weird appeared.

I don't know why, but when i use "view::share" into AppServiceProvider, my cart is empty (but my cart session is always filled).

Maybe developping an helper to count the items number could be a nice thing to have..

Regards,
Christophe

You can use LaraCart::count() , if you want the QTY's to be added to the count you can LaraCart::count(true)

Well same thing, it clear my cart :/

I just tested this :

{{ dump(LaraCart::get()->cart) }}

Total
{{ LaraCart::total() }}

Total Items
{{ LaraCart::count() }}
<br><br>
<form action="/cart/add">
    <button>Add Random Item</button>
</form>

<form action="/cart/fee">
    <button>Add $5.00 Delivery Fee</button>
</form>

<form action="/cart/destroy">
    <button>Destroy</button>
</form>

Ok, so it's nearly work, in fact, it's "LaraCart::getItems()" that doesn't work in my way.

This works (but the counter return 0)

//In AppServiceProvider
View::share('cart_items', LaraCart::count());

$items = LaraCart::get()->cart->items;
return view('customer.cart.cart', compact('items'));

This doesn't works

//In AppServiceProvider
View::share('cart_items', LaraCart::count());

$items = LaraCart::getItems();
return view('customer.cart.cart', compact('items'));

If you try to use share in the boot method its too early, and the cart has not been loaded yet. You can manually load the cart though to make it work in a middleware :

<?php

namespace App\Http\Middleware;

use Closure;
use LukePOLO\LaraCart\Facades\LaraCart;

class LoadCart
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        view()->share('totalItems', $LaraCart::count());
        return $next($request);
    }
}

Oh ok ! Perfect, you're solution works :D thank you for your fast support ^^

No problem, i don't think that is the best solution, you should be able to do it after the cart has loaded. You may be able todo it in the register method rather than the boot method.

Or mabye use a view composer instead
