Missing required parameters for [Route: ... ] [URI: ... ]

Posted 2 months ago by leux76

Hi guys, I am implementing a shopping cart but when I update the quantity of products, I get an error that I can not solve.

This is the table of my shopping cart (cart.blade.php):

                        @foreach($cart as $item)
                                <td> <img src="{{ $item->thumb }}"> </td>
                                <td>{{ $item->marca }}</td>
                                <td>{{ $item->modelo }}</td>
                                <td>{{ number_format($item->price,2) }}</td>
                                        value="{{ $item->quantity }}"
                                        id="product_{{ $item->id }}"
                                        class="btn btn-warning btn-update-item"
                                        data-href="{{ route('cart-update', $item->slug) }}'"
                                        data-id = "{{ $item->id }}"
                                        <i class="fa fa-refresh"></i>
                                <td>{{ $item->quantity }}</td>
                                <td>{{ number_format($item->price * $item->quantity,2) }}</td>
                                    <a href="{{ route('cart-delete', $item->slug) }}" class="btn btn-danger">
                                        <i class="fa fa-remove"></i>

Through JS I do the following (main.js):

$(document).ready(function() {

    // Update item cart
    $(".btn-update-item").on('click', function(e){
        var id = $(this).data('id');
        var href = $(this).data('href');
        var quantity = $("#product_" + id).val();
        window.location.href = href + "/" + quantity; 


The route I use is:

Route::get('cart/update/{product}/{quantity}', [
    'as' => 'cart-update',
    'uses' => '[email protected]'

And in my cartcontroller:

    public function update(Product $product,$quantity)
        $cart = session()->get('cart');
        $cart[$product->slug]->quantity = $quantity;
        session()->put('cart', $cart);
        return redirect()->route('cart-show');

But when I try tu actualize the quantity laravel show me this error:

Missing required parameters for [Route: cart-update] [URI: cart/update/{product}/{quantity}]. (View: C:\xampp\htdocs\watch\resources\views\store\cart.blade.php)

Thank you very much to all!!!
