Change button code to:
将按钮代码更改为：
<input name="hostel1" value="The Venetian" type="hidden">
<button class="submitBTN addnowBtn" type="submit"> Add Now</button>
In the controller, use this to get the value:
在控制器中，使用它来获取值：
$request->hostel1

Inside your controller function try this:
在您的控制器功能中试试这个：
Input::get('hostel1', 'NA');
// It will return its value ie `The Venetian` otherwise `NA`
Note:The second parameter of Input::get()is the default value.
注意：的第二个参数Input::get()是默认值。

Note: The easiest way to debug this, is via the Network tab in google chrome. You can see the header response data.
注意：最简单的调试方法是通过谷歌浏览器中的网络选项卡。您可以看到标头响应数据。
But the reason this is not working is probably because you are doing a POST Request . If you do a GET request you will get the value of the button.
但是这不起作用的原因可能是因为您正在执行 POST Request 。如果您执行 GET 请求，您将获得按钮的值。
An other reason could be that you are doing the submit trough javascript and doing an e.preventDefault()in that case you are not really sending the request. so PHP doesn't get the value.
另一个原因可能是您正在通过 javascript 进行提交，并且e.preventDefault()在这种情况下您并没有真正发送请求。所以 PHP 没有得到这个值。

I realized that anytime I try to set a name and value to a "submit" button, laravel doesn't retrieve the values in the request. So you might want to use a hidden field like this:
我意识到每当我尝试为“提交”按钮设置名称和值时，laravel 都不会检索请求中的值。所以你可能想使用这样的隐藏字段：
<input type="hidden" name="hostel1" value="hostel1">
and retrieve it on the server side like this:
并像这样在服务器端检索它：
$request->hostel1;

When you want to dd()your input params, do
当您想要dd()输入参数时，请执行

By using request namespace you can get value of any input parameters and also same for the submit button.
通过使用请求命名空间，您可以获得任何输入参数的值，并且提交按钮也是如此。
For this you have to include Request in controller like:
为此，您必须在控制器中包含请求，例如：
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class UserController extends Controller
{
/**
* Store a new user.
*
* @param Request $request
* @return Response
*/
public function store(Request $request)
{
$name = $request->input('name');
//IN your problem you can submit button value as
$submit_button = $request->input('hostel1');
}
}
For more details about the request you can follow:
