我有一个应用程序，用户可以选择主题和插件，但他们也可以选择这两个。因此，要检查所有可能的选项，我需要一个4子句if语句来检查每种情况。与此同时，这个if语句呈指数级增长，现在它非常大。我使用Repository来对某些位进行重构，但是它仍然太大而且不清楚。这是if语句
public function store(Request $request)
{
$selectedPlugin = null;
$selectedPlugins = array();
$price = null;
foreach($request->input('plugin') as $key => $value) {
if ($value === 'selected') {
$selectedPlugin = $key;
$plugin = Product::find($selectedPlugin);
if($plugin == null)
{
continue;
} elseif ($plugin != null) {
$price += $plugin->price;
echo "ID: " . $plugin->id . "<br>";
$selectedPlugins[$plugin->id] = $plugin->toArray();
$request->session()->put('chosen_plugins.' . 'PluginID' . $plugin->id, $plugin->toArray());
$request->session()->put('chosen_plugins.' . 'PluginID' . $plugin->id .'.composer_package', $plugin->productable->composer_package);
}
}
}
if(session()->exists('chosen_plugins') == true) {
$products = Session::get('chosen_plugins');
if(session()->exists('chosen_theme') == true)
{
$products['theme'] = Session::get('chosen_theme');
$themePrice = Session::get('chosen_theme')['price'];
$subtotal = $price + $themePrice;
$vat = 21/100 * $subtotal;
$priceSum = $subtotal + $vat;
} elseif (session()->exists('chosen_theme') == false) {
$subtotal = $price;
$vat = 21/100 * $subtotal;
$priceSum = $subtotal + $vat;
}
$data = [$subtotal, $vat, $priceSum];
$order = $this->_orderRepository->createOrderIfSessionExist($data, $products);
return redirect()->to('/ordersummary/'. $order->id);
} elseif (session()->exists('chosen_plugins') == false ) {
if(session()->exists('chosen_theme') == true)
{
$theme = Session::get('chosen_theme');
$subtotal = $theme['price'];
$vat = 21/100 * $subtotal;
$priceSum = $subtotal + $vat;
} elseif (session()->exists('chosen_theme') == false) {
$subtotal = 35;
$vat = 21/100 * $subtotal;
$priceSum = $subtotal + $vat;
}
$data = [$subtotal, $vat, $priceSum];
$order = $this->_orderRepository->createOrderIfSessionDoesntExist($data);
if (session()->exists('chosen_theme') == true) {
$orderItems = new Orderitems;
$orderItems->order_id = $order->id;
$orderItems->product_id = $theme['id'];
$orderItems->price = $theme['price'];
$orderItems->save();
return redirect()->to('/ordersummary/'. $order->id);
} elseif (session()->exists('chosen_theme') == false) {
return redirect()->to('/ordersummary/'. $order->id);
}
}
}
我需要一些帮助来重构这个if语句。提前谢谢！
