How to receive JSON object in PHP?
ajax, javascript, jquery, json, php
Solution
POST needs key value pairs, but you're just sending it one value (a JSON string) without a key. It needs to be an array.
Secondly, you need to decode the JSON before you can use it in PHP as an array or object. `json_decode()` is used for that.
Problem
I'm trying to send a JSON object from an AJAX request to my server. I'm doing this with JQuery like this: ``` $.ajax({ type: "POST", url: settings.ajax.post, dataType: 'json', data: basket.aggregate(Basket.EXPORT_JSON, qty), success: function(data, textStatus, jqXHR) { if (typeof settings.ajax.success == "function") settings.ajax.success(data, textStatus, jqXHR); }, error: function(jqXHR, text, e) { if (typeof settings.ajax.error == "function") settings.ajax.error(jqXHR, text, e); } }); ``` The url is pointed to this file on the server: ``` <?php $to = "<my-email-address>"; $subject = "JSON test"; $message = "POST dump:\n\n"; foreach($_POST as $key=>$value) { $message .= $key . ":" . $value; } mail ($to, $subject, $message); exit; ?> ``` But the POST var seems to be empty, even though in Firebug I can see that the correct data was sent to the server: After each request is sent, the ajax error function is called, with an undefined error (I guess because there was no reply from the server? Or I don't know?)
