Yii2: isAjax returns false

Question

Im developing a search bar in yii2 using ajax. The problem is the Yii::$app->request->isAjax property always returns false

This is my action:

public function actionAjaxsearch() { if(Yii::$app->request->isAjax) { $keywords = Yii::$app->request->queryParams; Yii::$app->response->format = \yii\web\Response::FORMAT_JSON; return [ 'data' => $keywords, 'code' => 200 ]; } else throw new \yii\web\HttpException(404, 'Page not found.');

And this is my script:

$('#search-box').keyup(function( event ){ event.preventDefault(); $.ajax({ url: 'http://localhost/items/ajaxsearch', data: {keywords: $( '#search-box' ).val()}, type: 'GET', dataType: 'json', }).done(function(){ console.log('success'); }).fail(function( data ){ alert( data ); }).always(function(){ alert('finished'); }) });

If i dont use the if with Yii::$app->request->isAjax the controller just render the JSON with the data.

P.D The content of #search-box is succesfully passed.

Edit to @SilverFire

Dont have some in the dump

["HTTP_X_REQUESTED_WITH"] => not defined, ["HTTP_ACCEPT"]=> string(74) "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8", ["CONTENT_TYPE"] =>not defined, ["HTTP_CONTENT_TYPE"] =>not defined, ["REQUEST_METHOD"]=> string(3) "GET", ["HTTP_X_HTTP_METHOD_OVERRIDE"] =>not defined,

@SilverFire you need to see any specific variable? I'm programming on dev server in my work. So I prefer not show all $_SERVER — Sageth

Fair enough. Could you show HTTP_X_REQUESTED_WITH, HTTP_ACCEPT, CONTENT_TYPE, HTTP_CONTENT_TYPE, REQUEST_METHOD, HTTP_X_HTTP_METHOD_OVERRIDE — SilverFire

Well, your browser for some reasons does not send the HTTP_X_REQUESTED_WITH headers to the server.

It guess it might be related to: Missing X-Requested-With: XMLHttpRequest (causes 200 OK But Shows as Error?) and Cross-Domain AJAX doesn't send X-Requested-With header

I've tried to add the X-Requested-With header in the ajax request but still doesn't work.

Do you see this header on PHP side after you've added it in the ajax request?

It's the only way how server could guess that it's an Ajax request, so the problem relates at most XHR requests. Could you show a screenshot or text dump from the browser debug console with the detailed info about the request?
