I have been trying to find a way to determine ajax call in Laravel but i don't find any document regarding it.
I have a index()
function which i want to handle situation differently based on the nature of 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();
$data['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 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.
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";
}
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.
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
)
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.
$request->wantsJson()
// or
\Request::wantsJson() // not \Illuminate\Http\Request
if(Request::ajax())
Looks to be the right answer. http://laravel.com/api/5.0/Illuminate/Http/Request.html#method_ajax
For those working with AngularJS front-end, it does not use the Ajax header laravel is expecting. ( Read more )
Use Request::wantsJson() for AngularJS:
if(Request::wantsJson()) {
// Client wants JSON returned
}
Those who prefer to use laravel helpers they can check if a request is ajax using laravel request()
helper.
if(request()->ajax())
// code
public function index()
{
if(!$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'));
}
有时Request::ajax()
不起作用,然后使用\\Request::ajax()
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
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;
}
