How to handle json data, which I send via ajax request, in php script?

Question

I am sending some json data with ajax:

function send() {
    $.ajax({
        url: '/index.php?action=setShopOrdersGoods&order_id='+orderId,
        type: 'post',
        dataType: 'json',
        success: function (data) {
            $('#target').html(data.msg);
        },
        data: JSON.stringify(goods)
    });
}

There are no problems with it. Firebug console screen:

Soajax request is sending okay. Now I need to handle it.

How I can do this?

echo __FILE__;
echo '<pre>';
var_dump($_POST);
echo '</pre>';
exit;

This code shows nothing. Looks like there are no data send via post. Firebug response tab of sent ajax request:

How I can handle json data in php file then?

how do you evaluate that your php shows nothing? If you just open the path to it it surely will show nothing since it needs a `post` request for that. Are you aware of that? You browser tools can show you the servers response for whem you send data via ajax. Try that. — Andresch Serj, Jun 18 '14 at 11:27
@DS9 If dumping `$_POST` shows nothing, it is very unlikely that `$_POST['items']` will show something right? — Andresch Serj, Jun 18 '14 at 11:28
I updated my question - added response - result of php code above. — Sharikov Vladislav, Jun 18 '14 at 11:28
your response tab shows ajax.php but you use index.php in your json. this doesn't seem right — Andresch Serj, Jun 18 '14 at 11:30
@bloodyKnuckles No. It is in `/modules/ajax.php` file. This file is included only it somebody doing ajax request. — Sharikov Vladislav, Jun 18 '14 at 11:31
Your approach to get data from $_POST is correct (*given you send data via post*) and not the problem here. The error seems to be somewhere else. It is dubious that you send to index.php and get results in your firefox tab by ajax.php. — Andresch Serj, Jun 18 '14 at 11:31

You are calling index.php with your AJAX call. Put `var_dump()` in your index.php page, or change your ajax to point to ajax.php — bloodyKnuckles, Jun 18 '14 at 11:32
@bloodyKnuckles As you see in my 2nd screen _correct_ file giving result. — Sharikov Vladislav, Jun 18 '14 at 11:33
@bloody `index.php`. In `index.php` I have section, which detects ajax request and load `/modules/ajax.php` file, as I said below. — Sharikov Vladislav, Jun 18 '14 at 11:35

Json data does not receive in post.

$json = file_get_contents('php://input');
$post = json_decode($json, TRUE);

echo __FILE__;
echo '<pre>';
var_dump($post);
echo '</pre>';
exit;

Worked. What is `php://input`? – Sharikov Vladislav Jun 18 '14 at 11:34
`php://input`: http://stackoverflow.com/questions/8893574/php-php-input-vs-post Cool. – bloodyKnuckles Jun 18 '14 at 11:37
json data is saved into tmp, which is get through it – Samar Haider Jun 18 '14 at 11:38
Wow. I did not know that. How did i not know that? Frameworks! They take all the work out of your hands and leave you clueless :-D – Andresch Serj Jun 18 '14 at 11:41
@AndreschSerj I am not using framework. Simple logic. The question was not about how I handle ajax request etc. I asked why I am getting nothing when `var_dump($_POST)` and author of this answer helped me. – Sharikov Vladislav Jun 18 '14 at 12:06
