Laravel: Send Data to Controller via AJAX Without Form - php

Question

I need to send data via JS to a Laravel controller on a button click. I'm not using any form because the data is being created dynamically.
Every time i try to send the data, i get an Internal Server Error (500), but unable to catch that exception in the controller or the laravel.log file.
Here's what i'm doing:
Route:
Route::post('section/saveContactItems', 'SectionController#saveContactItems');
Controller:
public function saveContactItems($id, $type, $items, $languageID = "PT"){ ... }
JS:
$('button').on("click", function (evt) {
evt.preventDefault();
var items = [];
var id = $("#id").val();
var languageID = $("#languageID").val();
var data = { id: id, type: type, items: JSON.stringify(items), languageID: languageID };
$.ajax({
url: "/section/saveContactItems",
type: "POST",
data: data,
cache: false,
contentType: 'application/json; charset=utf-8',
processData: false,
success: function (response)
{
console.log(response);
}
});
});
What am i doing wrong? How can i accomplish this?
UPDATE: Thanks to #ShaktiPhartiyal's answer (and #Sanchit's help) i was able to solve my issue. In case some else comes into a similar problem, after following #Shakti's answer i wasn't able to access the data in the controller. So, i had to stringify the data before sending it to the server:
data: JSON.stringify(data),

You do not need to use
public function saveContactItems($id, $type, $items, $languageID = "PT"){ ... }
You have to do the following:
public function saveContactItems()
{
$id = Input::get('id');
$type = Input::get('type');
$items = Input::get('items');
$languageID = Input::get('languageID');
}
and yes as #Sanchit Gupta suggested you need to send the CSRF token with the request:
Methods to send CSRF token in AJAX:
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
If you use this approach you need to set a meta tag like so:
<meta name="csrf-token" content="{{csrf_token()}}">
or
data: {
"_token": "{{ csrf_token() }}",
"id": id
}
UPDATE
as #Sanchit Gupta pointed out use the Input facade like so:
use Input;
