Laravel搜索的时候分页并携带参数

筛选分页每页的条数：

<select class="form-control" id="perPage" name="perPage">
@foreach ( [10,20,30,50] as $e)
<option value="{{$e}}" {{ $e==request('perPage') ? 'selected' : '' }} >{{$e}}</option>
@endforeach
</select>

路由：

Route::get('customer/index/{customer_type?}', 'CustomerController@index');

public function index($customer_type = null) {
$search = request('search');
$perPage = request('perPage') ? request('perPage') : 10;
$customer_type = $customer_type ? $customer_type : request('customer_type');
$data = Customer::select(['id', 'email', 'user_name', 'nick_name', 'phone', 'create_time'])
->where('customer_type', '=', $customer_type)
->where(function ($query) use ($search) {
if ($search) {
$query->where('user_name', 'like', '%' . $search . '%')
->orWhere('nick_name', 'like', '%' . $search . '%')
->orWhere('phone', 'like', '%' . $search . '%')
->orWhere('email', 'like', '%' . $search . '%');
}
})
->orderBy('create_time', 'desc')
->paginate($perPage);
//追加额外参数，例如搜索条件
$appendData = $data->appends(array(
'search' => $search,
'customer_type' => $customer_type,
'perPage' => $perPage,
));
return view('admin/customerList', compact('data'));
}

效果图：

@section('content')
<div class="wrapper wrapper-content animated fadeInRight">
<div class="row">
<div class="col-sm-12">
<div class="ibox float-e-margins">
