Laravel 5: Fetch ajax data in route and pass to controller - php

Question

I'm using Laravel 5 and want to make ajax call to a controller with some data:
$.ajax({
url : "/getOrgById",
data : JSON.stringify({id:1})
})
The routes.php has:
Route::get('/getOrgById', 'HomeController#getOrgById');
HomeController.php:
public function getOrgById($data) {
//code here fails with message 'Missing argument 1 for HomeController::getOrgById()
}
How can I pass the data from ajax to route and then to controller?

Answer 1

I think the below example is what you're looking for
Route
Route::post('/getOrgById', 'HomeController#getOrgById');
Controller
public function getOrgById(Request $request) {
$id = $request->input('id');
}
JS
var myJsonData = {id: 1}
$.post('/getOrgById', myJsonData, function(response) {
//handle response
})

Answer 2

You should really look into resourceful controller actions. If you are wanting to fetch an organisation by its ID then you have an organisaiton entity, so create a corresponding organisation controller. This controller can then have a method to show an organisation by on its primary key value:
class OrganisationController
{
public function show($id)
{
return Organisation::findOrFail($id);
}
}
The route for this would look like:
Route::get('/organisations/{id}', 'OrganisationController#show');
You can then request this route via AJAX like so:
$.ajax({
method: 'GET',
url: '/organisations/' + id
});

Answer 3

You can use Input to get your variable
public function getOrgById() {
$data = \Input::get('data')
}

Answer 4

You can define paramers in your route:
Route::get('/getOrgById/{id}', 'HomeController#getOrgById');
And call it through:
$.ajax({
url : "/getOrgById" + id
})

Answer 5

You were almost right, but when using $data in your function declaration you're actually requiring a Query String variable, rather than a form request.
You have to add your Form Request in your Controller method, like so:
public function getOrgById(Request $request){
// do something here...
return response()->json(array('foo' => 'bar'));
}

Try with this,
HTML Form
<div id="loadingResponse"></div>
{!!Form::open(array('url'=>'test/submit', 'id'=>'submitForm','method'=>'POST'))!!}
{{Form::token()}}
<input type="text" name="data"/>
<button type="submit" class="btn btn-small btn-info">Send Data</button>
{{Form::close()}}
JS Ajax
$("#submitForm").submit(function(event) {
event.preventDefault();
$.ajax({
url : 'test/submit',
data : new FormData($("#submitForm")[0]),
dataType : 'JSON',
type : 'POST',
beforeSend: function(){
$("#loadingResponse").html("<img src='{{asset('img/loading.gif')}}' />");
},
success: function(response){
console.log(response);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log('Error '+xhr.status+' | '+thrownError);
},
});
});
PHP Route
...
Route::post("test/submit","TestController#submit");
...
PHP Controller
class TestController extends Controller
{
...
public function submit(Request $request)
{
response()->json(['msj' => $request->input('data')]);
}
...
}

ajax:
$.ajax({
type:'get',
url:'/getOrgById',
data:{
id:1
},
success:function(res){
}
});
routes.php:
Route::get('/getOrgById', 'HomeController#getOrgById');
HomeController.php:
public function getOrgById(Request $request) {
dd($request);
}
