How to send data from a button click to a controller in laravel 4
提问by user1072337
I am trying to send the id data from a button back to one of my controllers on button click. Depending on the id sent, I want the controller function to redirect the user to different views.
我试图在单击按钮时将 id 数据从按钮发送回我的控制器之一。根据发送的 id，我希望控制器功能将用户重定向到不同的视图。
Button:
按钮：
<a href="/oauth/facebook" id="{{$artist->id}}" class="sign">
/oauth/facebook route:
/oauth/facebook 路线：
Route::get('oauth/{provider}', 'Oauth2Controller@action_session')->before('guest');
Function action_session in Oauth2Controller:
Oauth2Controller 中的函数 action_session：
public function action_session($provider) {
$id=Input::get('id');
if($id > 5) {
return Redirect::to('/fans');
}
else {
return Redirect::to('/artists');
}
}
I tried using ajax but it seems that the oauth/facebook route is called on button click first, before the ajax request can go through (so the $id field is blank when the controller runs). Is there any way to do this? Thank you.
我尝试使用 ajax，但似乎在单击按钮时首先调用 oauth/facebook 路由，然后才能通过 ajax 请求（因此 $id 字段在控制器运行时为空）。有没有办法做到这一点？谢谢你。

You won't find the id in the input using this approach, but you could extend the route with an optional (unless you want it for all providers) parameter like this:
您不会使用这种方法在输入中找到 id，但是您可以使用一个可选的（除非您希望所有提供者都使用它）参数来扩展路由，如下所示：
Route
路线
Route::get('oauth/{provider}/{id?}', 'Oauth2Controller@action_session')->before('guest');
Controller
控制器
public function action_session($provider, $id = null) {
if ($id > 5) {
return Redirect::to('fans');
} else {
return Redirect::to('artists');
}
}
Button
按钮
<a href="/oauth/facebook/{{$artist->id}}" class="sign">...</a>
