Laravel array $request->all() empty

Question

I'm working on a shopping cart with Laravel.

I have :

Routes :

Route::post('/panier/ajouter', 'CartController@store')->name('cart.store');
Route::patch('/panier/{product}', 'CartController@update')->name('cart.update');

View :

<table class="table" id="table-shoppingcart">
                <thead>
                    <tr>
                        <th class="text-center" id="item-title-shoppingcart"></th>
                        <th class="text-center" id="size-title-shoppingcart">Taille</th>
                        <th class="text-center" id="quantity-title-shoppingcart">Quantité</th>
                        <th class="text-center" id="price-title-shoppingcart">Prix</th>
                        {{-- <th class="text-center" id="delete-title-shoppingcart"></th> --}}
                    </tr>
                </thead>
                <tbody>
                    @foreach (Cart::content() as $product)
                    <tr>

                        <th><img class="text-center item-content-shoppingcart" src="{{ $product->model->image }}"></th>
                        <td class="text-center td-table-shoppingcart size-content-shoppingcart">S</td>
                        <td class="td-table-shoppingcart quantity-content-shoppingcart">
                            <select name="quantity" class="custom-select text-center quantity" id="quantity" data-id="{{ $product->rowId }}">
                                @for ($i = 0; $i < 5 + 1 ; $i++)
                                <option id="quantity-option" {{ $product->qty == $i ? 'selected' : '' }}>{{ $i }}</option>
                            @endfor
                            </select>
                        </td>
                        <td class="text-center td-table-shoppingcart price-content-shoppingcart">{{ getPrice($product->subtotal()) }}</td>

                    </tr>
            @endforeach
                </tbody>
            </table>

Ajax request :

$("#quantity").change(function(){
    const classname = document.querySelectorAll('#quantity')
    Array.from(classname).forEach(function(element) {
        console.log(element);
        let id = element.getAttribute('data-id')
        axios.patch(`/panier/${id}`, {
            quantity: this.value
        })
        .then(function (response) {
           // console.log(response);
           console.log("refresh");
            $("#table-shoppingcart").load(location.href + " #table-shoppingcart");
        })
        .catch(function (error) {
            console.log("erreur");
           // console.log(error);
        });
    })
});

I need to get the quantity in my controller so i try :

public function update(Request $request)
    {
        $data = $request->json()->all();
        Log::info($data);
        return response()->json(['success' => 'Cart Quantity Has Been Updated']);
    }

But when i try to get a $data value, my array is empty like this in my log :

[2020-02-22 10:49:46] local.INFO: array ()

I tryed to change :

$data = $request->json()->all();

To

$data = $request->all();

But same problem.

Do you have any idea ?

Thanks !

I think that because axios.patch is now working properly refer this stackoverflow.com/questions/51170564/… — Chamara Abeysekara

I tryed this. Same error but i see in my array the row_method but not quantity. So i tryed to change quantity:this.value to quantity:5 to test. And i get the row quantity now. So this problem is quantity:this.value in ajax request. Do you have an idea ? — Guetguet

this is referring local scope in JS . since you are using Jquery I don't see the point of using this. you need to inject the event to you change function and from there you can get the value. let me know if need you need post it answer — Chamara Abeysekara

Laravel cheats with PUT/PATCH/DELETE etc requests. These need to be POST requests with the extra variable '_method' set to the request type (e.g.) PATCH.
