How to get Ajax post request by symfony2 Controller

Question

I send text message like this

html markup

<textarea id="request" cols="20" rows="4"></textarea> 

javascript code

var data = {request : $('#request').val()};  $.ajax({     type: "POST",     url: "{{ path('acme_member_msgPost') }}",     data: data,     success: function (data, dataType) {         alert(data);     },     error: function (XMLHttpRequest, textStatus, errorThrown) {         alert('Error : ' + errorThrown);     } }); 

symfony2 controller code

$request = $this->container->get('request'); $text = $request->request->get('data'); 

but $text is null ...

I have tried normal post request (not Ajax) by firefox http request tester.

/app_dev.php/member/msgPost 

Controller works and $text has a value.

So I think the php code is OK, there is the problem on Ajax side, however

'success:function' is called as if succeeded.

How can you get the contents of javascript data structure?

Answer 1

First, you don't need to access the container in your controller as it already implements ContainerAware

So basically your code should look like this in your Controller.php

public function ajaxAction(Request $request) {     $data = $request->request->get('request'); } 

Also, make sure by the data you are sending is not null by using console.log(data) in the JS of your application.

And finally the answer of your question : you are not using the right variable, you need to access the value of $('#request').val() but you stored it in a request variable and you used a data variable name in your controller.

Consider changing the name of the variable, because it's confusing.

Answer 2

If you're sending the data as JSON — not as form urlencoded — you need to access the request body directly:

$data = json_decode($request->getContent());
