您需要遍历客户以检查是否有匹配的客户ID和包ID。

例如：

public function redirectpackage(Request $request)
{

$customers = Customer::all();

foreach ($customers as $customer) {

    if($customer->id', $request->customer_id) and 
 ($customer->packages->id', $request->package_id) {

        return view('index.customer.customerabout'); 
    } else
    {
        return redirect()->intended(route('home'));
    }
}

这应该让你开始。您需要进行修改以适合您的模型和关系。
