Insert Backbone.js model into MySQL database

Question

I have a backbone.js model with some defaults and an url:

var Box = Backbone.Model.extend({
    url: \"./save.php\",
    defaults: {
        x: 0,
        y:         


        

Answer 1

You forgot to send ID.

//$id = $_POST['cid'];

Make Id to AUTO_INCREMENT and remove from code:

$id = $_POST['cid'];

mysql_query("INSERT INTO boxes (x, y, w, h)
                         VALUES('$x', '$y', '$w', '$h')
                       ") or die(mysql_error());
