AJAX post returns 500 error - Kenneth_H - 02-18-2015

Hi
I have tried to build an installer for my codeigniter application and after completing af small form for collecting the database information it should execute a method for setting everything up.
This function is located in the install controller and the method is called runci and takes no arguments.
Currently looks like this:

PHP Code:
$data = array(
                'status' => 'OK',
                'http_response' => 200,
                'message' => 'JSON data recieved'
            );
            return json_encode($data); 

My JS looks like this and is written in-line at the bottom of my view-file:

Code:
//AJAX call to submit and install

            $(document).ready(function(){

                var formdata = <?php print json_encode($_POST); ?>;

                console.log(formdata);

                try {

                    $.post('<?php print site_url(); ?>install/runci', formdata);

                }

                catch(e) {

                    console.log(e);

                }

            });

HTML output is correct, but after outputting the formdata to the console and then posting, I get this error back in the console:

Code:
POST http://ignitercms.khit.dev/install/runci 500 (Internal Server Error)

I know that something is wrong, but I cannot see what.

Only change from default CI 2.2.1 is that I have added wiredesignz HMVC Modular Extentions

It could be because you are returning your json instead of echoing it out back to the browser during the ajax request?

I have tried changing from return to echo and even to print, but still gives me same error in the console and nothing in CI log or php error log.

I fixed the issue. Seems like it could not handle it via post, so changed it to run using get requests.

Code:
//AJAX call to submit and install

 $(document).ready(function(){

     var formdata = <?php print json_encode($this->input->post(NULL, TRUE)); ?>;

     console.log(formdata);

     $.ajax({

         type: "GET",

         url: "<?php print site_url('install/runci'); ?>",

         data: formdata,

         success: function(msg) {

             console.log(msg);

         }

     });

 });
