Post JSON to Codeigniter controller

Question

I am trying to receive and parse a JSON object sent in a POST request using Codeigniter but I cannot \"find\" it.

This is my controller code:

public

I know this is an old post, but for others looking, this might be helpful:

On the browser side, I create my data packet using code similar to this pattern:

    var form_data = { };
    $.each($('#mvt_dialog_form').serializeArray(), function() {
        form_data[this.name] = this.value;
    }); 

   // add the address data to the payload
   var result = { 
        form_data: form_data,
        locations: addressData,
        selected_location:  selectedLocation
    };

   // now wrap it all up with a pretty bow
   // Seriously, the key:value format is required for codeigniter INPUT class to be able to "see"
   var movement = {
       movement_dlg: JSON.stringify(result)
   };

I then "post" movement to the server. In the controller, I then use the following logic:

    // Perform XSS filtering
    $postData = $this->input->post(NULL, TRUE);
    $result = json_decode($postData['movement_dlg']);
