Pass JSON string via POST to PHP : <p>I have a page that is part of CRUD on which I can edit my data and send it to Update action of my php app. Basically, it is a HTML form with input fields. 
On this page I'm trying to implement some kind of drag-n-drop list arrangement via jQuery plugin. After sorting elements I create an array by js script that holds my hierarchy and it looks like this:</p>

<pre><code>[
    {
        "id": 21,
        "name": "John"
    },
    [
        {
            "id": 25,
            "name": "Bill"
        },
        {
            "id": 20,
            "name": "Ann"
        }
    ],
    {
        "id": 18,
        "name": "Sally"
    },
    {
        "id": 24,
        "name": "Tom"
    }
]
</code></pre>

<p>Now, how can I pass this array from javascript to my update action via POST with the rest of my form so I can store it in DB in a proper JSON format?</p>
