Laravel Applications Invalid argument supplied for foreach() Errors - php

Question

I am learning PHP Laravel and I am developing shopping cart project. I am able to add the product into list but, when I click shopping cart link. I am getting following error.
Facade\Ignition\Exceptions\ViewException
Invalid argument supplied for foreach() (View: C:\Users\Khundokar Nirjor\Desktop\laravel Tutorial\shopping-cart\resources\views\shop\shopping-cart.blade.php)
Here is my Router
Route::get('/shopping-cart',[
'uses' => 'ProductController#getCart',
'as' => 'product.shopppingCart'
]);
Here is my header.blade.php code.
<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li><a href="{{route ('product.shopppingCart')}}"><i class="fa fa-shopping-cart" aria-hidden="true"></i> Shopping Cart
<span class="badge">{{ Session::has('cart') ? Session::get('cart')->totalQty : '' }}</span>
</a>
</li>
<li class="dropdown">

#endif
<li role="separator" class="divider"></li>
</ul>
</li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>

Here is my controller code
public function getCart()
{
if(!Session :: has('cart') ){
return view ('shop.shopping-cart');
}
$oldCart = Session::get('cart');
$cart = new Cart($oldCart);
return view ('shop.shopping-cart' , ['products' => $cart->items, 'totalPrice'=>$cart->totalPrice]);
}
Here is screen shot when I clicked the shopping-cart link

Answer 1

Try like this
#if(!empty($products) && count($products) > 0)
#foreach($products as $product)
// your code here
#endforeach // typo in foreach fixed
#endif

Answer 2

You're getting this error cuase of sometime your products array is empty. So whenever you call foreach make sure to check the array is not empty.
#if(!empty($products)
#foreach($products as $product)
//code here
#endforech
#endif
Make your code like this your error will be gone.
