ajax post request handle data in symfony2 controller

Question

i really don't understand how to handle with post data from ajax request. This is my javascript:

$.ajax({
     type: "POST",
     url: Routing.generate('save'),
     contentType: 'application/json; charset=UTF-8',
     data: {
          title: title,                
          description: description,
          questions: questions,              
         }
  });

The only way to get the data inside my controller action is this:

$content = $request->getContent()

$content is a url parameter string. Why don't i get the data normally with:

$request->get('title')

What is the correct way to handle the post data with jquery ajax methd?

Thank you very much.

EDIT

So, i found out the following issue:

In my current project the request looks like this:

$.ajax({
            type: "POST",
            url: Routing.generate('poll_save'),                
            data: {
                title: title                    
            }
        })

The data is requested via Request Payload but i don't know why.

In a clean project the request looks like this:

$.ajax({
                type: "POST",
                url: '{{path('_demo')}}',                    
                data: {
                    title: 'title',                
                    description: 'description',
                    questions: 'questions',
                    pollid: 1                        
                }
            })

Anything in my project is going wrong. Do you have an idea why the data is requested via Request Payload?

Do you use the request object in your controller?

<?php
namespace Acme\DemoBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
//...other things to use

class MyController extends Controller
{
    public function handleRequestAction() {

        $request = $this->get('request');
        //request your data
        $title   = $request->get('title');
        //or in one line
        $title   = $this->get('request')->request->get('title');
    }
}
?>

This is my normal way when I want to get data from an ajax call. Could you post what $content contains?

I see no problem with posting the data like you did. Constructing a json object might be helpful but the way you're doing it seems fine to me. I did this too.

EDIT

Normally you could also access all data in the request by doing this:

$all = $request->request->all();

Maybe you could then var_dump() the variables to see if something is in them.

$request->request->all(); was also empty. only getContent() gaves me any data. when i add the data to the url part, everything is fine. but i need to send the data via the data parameter because the post data can be very large.

how does your ajax method look like?

SirDerpington Over a year ago

Like yours, but I'm not using the bundle to generate routes (forgot the name of the bundle). Perhaps the problem is that you define a contentType. Did you try to leave it out and see what happens? jQuery Docu says "Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases"

Wolf-Tech Over a year ago

only getContent() has content, the rest is empty. I left contentType alos empty, it was the same result.

You can construct your json object and pass the JSON object to your controller using JSON.stringify.

https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON/stringify

var obj = {
      title: title,                
      description: description,
      questions: questions              
};

$.ajax({
 type: "POST",
 url: Routing.generate('save'),
 contentType: 'application/json; charset=UTF-8',
 data: JSON.stringify(obj)
});

And this is the normal workflow? I thought the ajax mehtod will handle it alone?

anazimok Over a year ago

Yes, because $.ajax does not serialize the data to JSON.

Wolf-Tech Over a year ago

But why can't i use the normal requets methods? I only get the data via $request->getContent()

quiz - form name serialize -populate the variables

 $.ajax({
            url: $("#quiz").attr("action"),
            data: $("#quiz").serialize(),
            type: 'POST'
 });

or

$.ajax({
                url: $("#commentForm").attr("action"),
                data: {
                    comment: commentFormID.val()
                },
                type: 'POST'
});

Controller - More like what previous comments suggested.

$request = $this->get('request');
$usercomment=$request->request->get('parameterName');

Why Json? I meant is a requirement to content type json? if not, this is the way I handle ajax and using FOSRoutingbundle that I can see you are using.

$(document).ready(function(){
    $('#myForm').submit( function(e){       

        e.preventDefault();
        var $form = $(this);
        var $formPHP = $form.serializeArray();
        var $url = Routing.generate( 'route_to_use');

        $.post( $url, $formPHP, function(data){
        .....
        });

    });    
});

Then in the controller you can use as a normal request.
