Ajax-post: 400 Bad request: Missing required parameters

I was happy that Yii seemed to be quite intelligent with my ajax calls. But then I realized that I have forgotten to declare method:‘POST’. After adding this the calls produce the Bad Request error.

Is this wrong?



  contentType: 'application/json; charset=utf-8',

  dataType: 'json',

  method: 'POST',

  url: '/some-other/do',

  data: {

    'itemId': itemId,

    'languageId': languageId,

    'newValue': newValue


  success: function (data) {



  error: function (data) {




After searching a while I thought I had to add those csrf things, which I don’t know much about. So I added to data



But this didn’t help. And I guess this is not the current way of doing it in Yii2-beta since the csrf is passed by the cookie, right?

The action that gets called has these params:

public function actionDo($itemId, languageId, $newValue) {



Is this not possible or am I doing anything wrong? Is there not so much magic in Yii2? It works with method:‘GET’ but not with ‘POST’.

Can you open some sort of dev tools, and post the sent and received HTTP headers perhaps?

So, do you think it should work actually?

I have got the headers with ‘Live HTTP headers’ in Firefox. The URL and the values differ a bit from the posted code - I simplified it for readibility.

What does this tell you?

You are posting to a method which require parameters. url should be /some-other/do?id=x or whatever
