Question

Hi i am having problems with an XHR post request.

in javascript:

self.xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
self.xhr.setRequestHeader("Method", "POST " + url + " HTTP/1.1");

In firebug:

Parametersapplication/x-www-form-urlencoded
{"u":"andrepadez","m":"\n...    
JSON    
m
    "sfdsfsdfdsfdsf"    
u
    "andrepadez"
Source
{"u":"andrepadez","m":"\nsfdsfsdfdsfdsf"}

In .NET, I post this to an .ASHX, and in the ProcessRequest i do:

StreamReader sr = new StreamReader(context.Request.InputStream, context.Request.ContentEncoding);
javaScriptSerializer.Deserialize<MyClass>(message);

and I have no problems.

I don’t know how to get the data in PHP, either $_POST and $_REQUEST are empty arrays.

Any help please?
thanks

You’ve not set a field name for the data being sent. PHP requires data coming in via POST to be in a fieldname=value format. _POST is an array like any other, and every value stored in a PHP array must have a key (which is the form field name).

You can try retrieving the data by reading from php://input:

$post_data = file_get_contents('php://input');

But the simplest solution is to provide a fieldname in your XHR call.
