Empty cart after page refresh.

[victorighalo]

I'm implementing a custom Buyable Model but after successfully adding to Cart, cart count returns the correct values but after page refresh cart count goes back to zero.

[fulopattila122]

Can you please post some code examples?

Can you please post some code examples?

use Illuminate\Http\Request;
use Vanilo\Cart\Facades\Cart;
use Vanilo\Cart\Contracts\CartItem;

//Add to Cart -- This works and returns quantity
$product = \App\Product::findBySlug($request->slug);
Cart::addItem($product, $request->qty);
return response()->json(['message' => 'Added to cart', 'cart_count' => Cart::itemCount()]);

//Returns zero after refresh
if(Cart::exists()){
$cart_count = Cart::itemCount();
$cart = Cart::model()->items;
}else{
$cart_count = 0;
$cart = [];
}
return view('pages.front.cart', compact('cart', 'cart_count'));

//Product model
use Spatie\MediaLibrary\HasMedia\HasMedia;
use Spatie\MediaLibrary\HasMedia\HasMediaTrait;
use Vanilo\Contracts\Buyable;
use Vanilo\Product\Models\Product as BaseProduct;
use Vanilo\Support\Traits\BuyableModel;
use Vanilo\Support\Traits\BuyableImageSpatieV7;
use willvincent\Rateable\Rateable;
use Illuminate\Database\Eloquent\Relations\MorphToMany;
use Vanilo\Category\Models\TaxonProxy;
use BrianFaust\Commentable\Traits\HasComments;

class Product extends BaseProduct implements Buyable, HasMedia
{
    use
        Rateable,
        BuyableModel,
        BuyableImageSpatieV7,
        HasComments,
        HasMediaTrait;

    public function taxons(): MorphToMany
    {
        return $this->morphToMany(
            TaxonProxy::modelClass(), 'model', 'model_taxons', 'model_id', 'taxon_id'
        );
    }
}

Can you please also include the use Class\Name section as well?

[victorighalo]

Can you please also include the use Class\Name section as well?

I've updated the code example

[fulopattila122]

Few tips:

1. You can use the HasTaxons trait on your product model.
2. You don't have to check whether the cart exists for the count, it's being done internally.
3. Don't access the Cart::model() directly unless you really, really, really (really?) need it. Use Cart::getItems() instead.

return view('pages.front.cart', ['cart' => Cart::getItems(), 'cart_count' => Cart::itemCount()]);

Regarding the bug: do you use the web middleware on the routes?

[victorighalo]

3. getItems

Thanks I have used the HasTaxons trait on my product model. I've updated the code to use Cart::getItems() instead, and yes, I use the Web middlleware in my controllers.

I noticed the user_id field in the cart table is null, could that be one of the problems?

[fulopattila122]

No, the user <-> cart assignment is completely optional.

Is the session working properly in your application?

Eg. if you store some value, can you get the value back after page refresh?

//store some data in controller
session()->put('hey', 'yo');

// ... refresh the page ...
session()->get('hey');
// Do you get 'yo' here?

Yes. Session works fine. I can store and retrieve the value.

What's the value of config('vanilo.cart.session_key') ?
What does session()->get(config('vanilo.cart.session_key')) give when adding something to the cart, and after refreshing the page?

[victorighalo]

What's the value of config('vanilo.cart.session_key') ?
What does session()->get(config('vanilo.cart.session_key')) give when adding something to the cart, and after refreshing the page?

config('vanilo.cart.session_key') = null

when adding to cart

session()->get(config('vanilo.cart.session_key'))  
array (size=3)
  '_token' => string 'rPjTNEhixJYj7ZeoRAkSWUJLRTdWtvxmZ8fuLUm5' (length=40)
  '_previous' => 
    array (size=1)
      'url' => string 'http://localhost/ecommerce-laravel/public/Toyota-bus/test-product-2' (length=67)
  '_flash' => 
    array (size=2)
      'old' => 
        array (size=0)
          empty
      'new' => 
        array (size=0)
          empty

after adding to cart

session()->get(config('vanilo.cart.session_key'))
array (size=1)
  '_token' => string 'rPjTNEhixJYj7ZeoRAkSWUJLRTdWtvxmZ8fuLUm5' (length=40)

after second refresh

array (size=3)
  '_token' => string 'rPjTNEhixJYj7ZeoRAkSWUJLRTdWtvxmZ8fuLUm5' (length=40)
  '_previous' => 
    array (size=1)

          empty
      'new' => 
        array (size=0)
          empty

config('vanilo.cart.session_key') = null this is the problem.

Can you post the contents of config/concord.php here? Do you have config/vanilo.php file?

[victorighalo]

My config/concrd.php file

<?php

return [
    'modules' => [
        Konekt\AppShell\Providers\ModuleServiceProvider::class => [
            'ui' => [
                'name' => 'Vanilo',
                'url' => '/admin/product'
            ]
        ],
        Vanilo\Framework\Providers\ModuleServiceProvider::class
    ]
];

I also don't have a config/vanilo.php file

[fulopattila122]

That's strange, because it looks as it should. What's the output of var_dump(config('vanilo')) ?

What do config('concord') and config('session') calls return?

Please how can I fix this?

[fulopattila122]

Your complete vanilo config is gone. Somehow you overwrote it.
The last thing I can think of: what's the content of vendor/vanilo/cart/src/resources/config/module/php ?

Can you maybe zip your entire project along with the vendor/ folder (remove sensitive parts) and make it available for download?

My OS says it's not a zip file. Please either fix it or send .tar.gz

I've checked your code. Here's what to do:

Move these 3 routes from routes/api.php => routes/web.php:

Route::post('/cart/add', 'CartController@add')->name('add_to_cart');
Route::post('/cart/update/{cart_item?}', 'CartController@update')->name('update_cart');
Route::post('/cart/destroy/{cart_item?}', 'CartController@destroy')->name('destroy_cart');

Remove api/cart/* from the except array in the App\Http\Middleware\VerifyCsrfToken class:

protected $except = [
    'api/cart/*' // <- remove
];

---

In general, Vanilo could do much more for you.
You're reimplementing a lots of existing Vanilo functionalities, often not in a proper way.
I suggest to re-read the docs and study the code of the demo app.

Thanks so much. It works now.
I'll have to take a deeper study of the Vanilo Docs so I can get things right. I will appreciate if you can point of some specific changes i can make to improve my use of Vanillo.

I'll do that in the coming days.
