Laravel - check if Ajax request - php

Question

I have been trying to find a way to determine Ajax calls in Laravel but I have not found any documentation about it.
I have an index() controller function where I want to handle the response differently based on the nature of the request. Basically this is a resource controller method that is bound to GET request.
public function index()
{
if(!$this->isLogin())
return Redirect::to('login');
if(isAjax()) // This is what I am needing.
{
return $JSON;
}
$data = array(
'records' => $this->table->fetchAll()
);
$this->setLayout(compact('data'));
}
I know the other methods of determining the Ajax request in PHP but I want something specific to Laravel.
Thanks
Updated:
I tried using
if(Request::ajax())
{
echo 'Ajax';
}
But I am receiving this error:
Non-static method Illuminate\Http\Request::ajax() should not be called statically, assuming $this from incompatible context
The class shows that this is not a static method.

Answer 1

Maybe this helps. You have to refer the #param
/**
* Display a listing of the resource.
*
* #param Illuminate\Http\Request $request
* #return Response
*/
public function index(Request $request)
{
if($request->ajax()){
return "AJAX";
}
return "HTTP";
}

$request->wantsJson()
You can try $request->wantsJson() if $request->ajax() does not work
$request->ajax() works if your JavaScript library sets an X-Requested-With HTTP header.
By default Laravel set this header in js/bootstrap.js
window.axios = require('axios');
window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
In my case, I used a different frontend code and I had to put this header manually for $request->ajax() to work.
But $request->wantsJson() will check the axios query without the need for a header X-Requested-With:
// Determine if the current request is asking for JSON. This checks Content-Type equals application/json.
$request->wantsJson()
// or
\Request::wantsJson() // not \Illuminate\Http\Request

Answer 3

To check an ajax request you can use if (Request::ajax())
Note:
If you are using laravel 5, then in the controller replace
use Illuminate\Http\Request;
with
use Request;
I hope it'll work.

Answer 4

You are using the wrong Request class. If you want to use the Facade like: Request::ajax() you have to import this class:
use Illuminate\Support\Facades\Request;
And not Illumiante\Http\Request
Another solution would be injecting an instance of the real request class:
public function index(Request $request){
if($request->ajax()){
return "AJAX";
}
(Now here you have to import Illuminate\Http\Request)

Answer 5

if(Request::ajax())
Looks to be the right answer.

Answer 6

For those working with AngularJS front-end, it does not use the Ajax header laravel is expecting. (Read more)
Use Request::wantsJson() for AngularJS:
if(Request::wantsJson()) {
// Client wants JSON returned
}

Answer 7

Those who prefer to use laravel helpers they can check if a request is ajax using laravel request() helper.
if(request()->ajax())
// code

Answer 8

public function index()
{
if(!$this->isLogin())
return Redirect::to('login');
if(Request::ajax()) // This is check ajax request
{
return $JSON;
}
$data = array();
$data['records'] = $this->table->fetchAll();
$this->setLayout(compact('data'));
}

Answer 9

Sometimes Request::ajax() doesn't work, then use \Request::ajax()

Answer 10

Do something like this
public function functionName(User $user): string
{
(string) $message = "";
// check if request is ajax
if(request()->ajax())
{
if($this->isOwner($user->id)){
$message = 'success';
}else{
$message = "You are unauthorized to perform this action.";
}
}else{
$message = 'Wrong server request';
}
return $message;
}

Answer 11

after writing the jquery code perform this validation in your route or in controller.
$.ajax({
url: "/id/edit",
data:
name:name,
method:'get',
success:function(data){
console.log(data);}
});
Route::get('/', function(){
if(Request::ajax()){
return 'it's ajax request';}
});

Most of the answers are working fine. We can also check the request header
request()->header('Accept')=='application/json'
to check the request type
