Hello,

there is a function which saves and sends post request:

save_car: function(e) {

      if (e.keyCode != 13) return;
      if (!this.brand.val()) return;

      Cars.create({brand: this.brand.val(), color: this.color.val(), max_speed: this.max_speed.val() });

      this.brand.val('');
      this.color.val('');
      this.max_speed.val('');
    },

{brand:sad, color:sf, max_speed:sd, order:1, remove:false}
brand: "sad"
color: "sf"
max_speed: "sd"
order: 1
remove: false

So as we see from headers there is post request with various parameters.

Now the php function:

public function index()
    {

        $this->load->model('Backbone_model');

        //$res = $this->Backbone_model->get_all();

        if (isset($_GET)) {
            echo json_encode($this->Backbone_model->get_all());
        }
        else if (isset($_POST)) {

            echo 'ts';

            //SELECT name as brand, address as color, tel as max_speed FROM contacts

            $sql = "INSERT INTO contacts (name, address, tel) VALUES (?, ?, ?)";
            $this->db->query($sql, array($_POST['brand'], $_POST['color'], $_POST['max_speed'] ));

            echo $this->db->last_query();

        }

        echo 'asss';

        print_r($_REQUEST);

    }

it returns;

[{"brand":"Darius","color":"maciuleviciaus 30","max_speed":"866612345"},{"brand":"arvydas","color":"zidiku","max_speed":"866"}]asssArray()

so it looks like it see $_GET request. WHy this could be? It returns json and later string 'asss'

changed checking a bit:

else if ($_SERVER['REQUEST_METHOD'] == 'POST') {

and now it recognizes post. But still dont see any variables:

print_r($_POST);

just shows: Array()

Without seeing the snippet of code that performs the POST "we" are unable to suggest where the issue lies.

      Cars.create({brand: this.brand.val(), color: this.color.val(), max_speed: this.max_speed.val() });
      this.brand.val('');
      this.color.val('');
      this.max_speed.val('');
    },

There is Cars.create

The create method in backbone triggers they sync.

http://backbonejs.org/#Sync

The default sync handler maps CRUD to REST like so:

create → POST /collection
read → GET /collection[/id]
update → PUT /collection/id
delete → DELETE /collection/id

I've never used backbone, and just trying to get my head around it's concepts.. but the documentation appears to suggest that the .create will fire a "request"

Creating a model will cause an immediate "add" event to be triggered on the collection, a "request" event as the new model is sent to the server, as well as a....

I may be way off :-)

btw I have heard that globals are bad practice.

So I want to ask is using $GLOBALS['HTTP_RAW_POST_DATA'] bad? Then how can I replace it? WHen there is no data in $_POST array.

But I googled a bit and there is different thing - global $var; so syntax looks bit different, so maybe only this is bad and $GLOBALS is not bad?

Found how to get $_POST working:

in javascript document readu function add:

Backbone.emulateJSON = true;

and now we can see there is index 'model' in $_POST array. Its json encoded so just decode and use.
