我在网站上有购物车,到目前为止一切都很完美。现在,我正在尝试为管理员可以在后端(已经完成)添加的每个产品以及客户订购产品以减少数据库中的数量。
据我所说,管理面板已准备就绪,可以将数量添加到保存在数据库中的产品中。这是我的购物车提交控制器
public function orderSubmit() {
$cart = Session::get(self::CART_SESSION_KEY, array());
if (count($cart) < 1) {
return Redirect::to('/');
}
$validatorRules = array(
'captcha' => 'required|captcha'
);
Input::merge(array_map('trim', Input::all()));
$validator = Validator::make(Input::all(), $validatorRules);
if ($validator->fails()) {
return Redirect::to('/cart/order?_token=' . csrf_token())->withErrors($validator->errors())->withInput(Input::except(['captcha']));
}
$order = new Order();
$order->user_id = self::$user->user_id;
$order->data = json_encode($cart, true);
$order->info = Input::get('additional_info');
$order->save();
Session::put(self::CART_SESSION_KEY, array());
return Redirect::to('/)->with('message_success', 'Order created! We will contact you shortly to confirm your order details.');
}
购物车保存在$order->data = json_encode($cart, true);
中,并保存在产品的数据库信息等中
{"title":"Test Product","description":"You save 25%","quantity":1,"price":135}
如果上面有多个产品,那么数组也会有它们。
我能理解的是如何提取订购的产品以及产品的数量,以便我以后可以更新每种产品的数据库数量字段?
我甚至不知道从哪里开始。

假设$cart
是一个数组且基于您提供的json,您需要:
$cart
,否则几乎不可能知道该订单的产品是什么使用$cart
上每个产品的产品ID,您现在可以循环购物车产品并进行更新。类似下面的代码。
public function orderSubmit() {
$cart = Session::get(self::CART_SESSION_KEY, array());
if (count($cart) < 1) {
return Redirect::to('/');
}
$validatorRules = array(
'captcha' => 'required|captcha'
);
Input::merge(array_map('trim', Input::all()));
$validator = Validator::make(Input::all(), $validatorRules);
if ($validator->fails()) {
return Redirect::to('/cart/order?_token=' . csrf_token())->withErrors($validator->errors())->withInput(Input::except(['captcha']));
}
\DB::beginTransaction();
try {
$order = new Order();
$order->user_id = self::$user->user_id;
$order->data = json_encode($cart, true);
$order->info = Input::get('additional_info');
$order->save();
foreach ($cart as $item) {
$product = Product::find($item->id);
$product->decrement('votes', $item->quantity);
}
Session::put(self::CART_SESSION_KEY, array());
\DB::commit();
return Redirect::to('/')->with('message_success', 'Order created! We will contact you shortly to confirm your order details.');
} catch (\Exception $ex) {
\DB::rollback();
return Redirect::to('/cart/order?_token=' . csrf_token())->withErrors($ex->getMessage())->withInput(Input::except(['captcha']));
}
}
我添加了交易代码,以确保在订单正确存储时数量减少。

对于使用资源控制器或更简单/简单答案的用户:
public function create()
{
$stocks = Stock::all();
//dd($stocks);
return view('sales.create', compact('stocks'));
//$sales = Sale::pluck('stock_id')->prepend('stock_id');
//$sales = DB::table('stocks')->select('stock_id')->get();
//return view('sales.create')->with('sales',$sales);
}
public function store(Request $request)
{
$this->validate($request, [
'stock_id' => 'required',
'product_name' => 'required',
'sale_quantity' => 'required',
'unit_selling_price' => 'required',
'total_sales_cost' => 'required'
]);
//create stock
$sale = new Sale;
$sale->stock_id = $request->input('stock_id');
$sale->product_name = $request->input('product_name');
$sale->sale_quantity = $request->input('sale_quantity');
$sale->unit_selling_price = $request->input('unit_selling_price');
$sale->total_sales_cost = $request->input('total_sales_cost');
$sale->stock_quantity =
$sale->save();
DB::table('stocks')->where('stock_name', $request->input('product_name'))->decrement('stock_quantity', $request->input('sale_quantity'));
return redirect('/sales')->with('success', 'Sale Saved');
}
