Input data is stored in the session between requests. Are you redirecting after a request has processed, or are you trying to maintain inputs in the case a request is not validated, i.e. redirected back to the page with error messages?
输入数据存储在请求之间的会话中。您是在请求处理后重定向，还是在请求未验证的情况下尝试维护输入，即重定向回带有错误消息的页面？
In the first case you can use $request->session()->flash()to keep the data in the session after the request has processed.
在第一种情况下，您可以$request->session()->flash()在请求处理后将数据保留在会话中。
In the second case, data is flashed automatically and accessible through the old()helper method, as you have in your form example.
在第二种情况下，数据会自动刷新并通过old()辅助方法访问，就像您在表单示例中所做的那样。

try this. your form and controller method should be like
尝试这个。你的表单和控制器方法应该像
// form
//表格
<form action="{{url('user/manage')}}" method="post">
<input type="text" placeholder="From" name="from_date" value="{{$from_date}}" id="from_date" class="form-control">
<input type="text" placeholder="To" name="to_date" value="{{$to_date}}" id="to_date" class="form-control">
<input type="submit" value="Filter" name="submit" class="btn btn-default">
<input type="text" placeholder="Enter E mail" name="email_search" id="" value="{{old('email_search')}}" class="form-control">
<input type="hidden" name="_token" value="{{{ csrf_token() }}}" />
<input type="submit" value="Show" name="submit" class="btn btn-default">
</form>
// controller
//控制器
$data = [
'users'=>$users,
'from_date'=>$from,
'to_date'=>$to; ]
return view('show',$data);
]
