产品未从购物车中删除

Question

他试图从购物车中删除产品但它没有删除，任何修复它的建议，当我点击提交按钮然后它说 404|not found

控制者：

public function deleteCartProduct(Product $product)
{
    $oldCart = Session::has('cart') ? Session::get('cart') : null;
    $cart = new Cart($oldCart);
    $cart->delProduct($product);
    Session::put('cart', $cart);

    return redirect()->route('product.cart')->with('flash_message_success', 'Product product has been removed from Cart');
}

型号

public function deleteProduct($product)
{
    if ($this->contents) {
        if (array_key_exists($product->product_slug, $this->contents)) {
            $delProduct = $this->contents[$product->slug];
            $this->totalQty -= $delProduct['qty'];
            $this->totalPrice -= $delProduct['price'];
            array_forget($this->contents, $product->slug);
        }
    }
}

刀片文件

    @foreach($contents as $slug => $cartItem)
                      <form action="{{ route('deleteCartProduct', $product) }}" method="POST">

                      @endforeach

路线：

  Route::get('/cart/delete-product/{id}','ProductController@deleteCartProduct')->name('deleteCartProduct');

Answer 1

您的路线应该是 Route::delete 而不是 Route::get，然后在表单中添加以下内容：

@method('delete')

我在按钮上看到了你的错误：

<input type="submit" class="btn btn-danger value="Remove Product">

用这个改变它：

<input type="submit" class="btn btn-danger" value="Remove Product">

缺少报价..

编辑

你的路线应该是这样的：

Route::delete('/cart/delete-product/{id}','Admin\ProductController@deleteCartProduct')->name('deleteCartProduct');

Answer 2

您需要更改控制器中的代码，如下所示。

public function deleteCartProduct(Product $product)
{
     $oldCart = Session::has('cart') ? Session::get('cart') : null;
     $cart = new Cart($oldCart);
     $cart->deleteProduct($product);
     Session::put('cart', $cart);

     return redirect()->route('product.cart')->with('flash_message_success', 'Product product has been removed from Cart');
}

Answer 3

您在刀片中将其定义为 method="POST"。并在路线中“获得”。所以你需要把动词改成Route::post
