Q:

Post a form using ajax in Laravel

I know this question has been out there many times, however I am unable to get through this. 
Here is my route:
Route::post('/masters/board/edit', 'MastersController@editBoard');

My Controller:
public function editBoard() {
        $board = Board::findOrFail(Input::get('id'));
        $board->nick_name        = Input::get('nick_name');
        $board->board_name        = Input::get('board');
        $board->type                        = Input::get('type');
        $board->save();

        return Redirect::action('MastersController@getBoards');
    }

My JS:
$("#edit_form").submit(function(e) {
    e.preventDefault();

    var type = "#edit_form";

    var formData = {
          id : $(type + " #id").val(),
          nick_name : $(type + " #nick_name").val(),
          name : $(type + " #board").val()
      }

    $.ajax({
      type: "POST",
      url: "masters/board/edit",
      data: formData,
      success: function(data) {
        console.log(data);
      }
    });
  });
});

This is throwing an error:
[Error] Failed to load resource: the server responded with a status of 500 (Internal Server Error) (edit, line 0)

Can anyone see a reason why? 

A:

Add a meta tag with the csrf_token. 
<meta name="_token" content="{{ csrf_token() }}" />

And add that token to your data. 
var formData = {
  id : $(type + " #id").val(),
  nick_name : $(type + " #nick_name").val(),
  name : $(type + " #board").val()
  _token: $('meta[name="_token"]').attr('content')
}

If you are going to perform lot of post requests try the following. 
Use the following script to setup your ajax requests with the csrf token. 
$(function() {
  $.ajaxSetup({
    headers: {
      'X-CSRF-Token': $('meta[name="_token"]').attr('content')
    }
  });
});

If you are using laravel 5 this should work out of the box. 
If not you need to edit your app/filters.php file. 
Replace the csrf filter with the following. 
Route::filter('csrf', function() {
    $token = Request::ajax() ?  Request::header('X-CSRF-Token') : Input::get('_token');
    if (Session::token() ! = $token)
        throw new Illuminate\Session\TokenMismatchException;
});
