Backbone.js: POST request with empty value - post

Question

I am trying to make a POST request.
Here my code:
var myModel = new MydModel({
content: "ciao"
});
console.log(myModel.get("content")); // "ciao"
myModel.save();
If I look to the network activity it looks like this:
The response part {id:0, content:"", ……}
In the header part: Request Payload {"content":"ciao"}
Here my model:
define([], function () {
var MyModel = Backbone.Model.extend({
url: function url ()
{
return "http://localhost/users";
}
});
return MyModel;
});
Is it my problem or is it in the server part?

Answer 1

send/receive vs request/response
a server receives requests and sends responses
a client sends requests and receives responses
in short
if {id:0, content:"", ……} (the response) is wrong, it's your server
if {"content":"asdasdsa"} (the request) is wrong, it's your client

Answer 2

There is little problem with receiving JSON-payload that "Backbone-client" sends to your Apache-server.
All you need to do is to manually parse JSON-payload from input on the server side ("php://input", for PHP), like this:
if($_SERVER['REQUEST_METHOD'] == 'PUT' || $_SERVER['REQUEST_METHOD'] == 'POST') {
$postStr = file_get_contents("php://input");
//json_decode throws error or returns null if input is invalid json
try {
$json = json_decode($postStr, true);
if(empty($json)) {
throw new Exception("Not valid json");
}
//must not be json, try query str instead
} catch(Errfor $e) {
$postVars = parse_str($postStr);
foreach($postVars as $key=>$data) {
$_POST[$key] = $data;
}
}
}
