I've been trying to get http_sendpost to send a string with the data setting and have php store the data in a var for use in the online code.

Example :
http_sendpost("http://websiteName/pageName.php","mydata=250");

Regardless of what code I use in PHP, the data always comes up empty. Things like : $_GET["mydata"] are not detecting the data at the end of the url.

What am I doing wrong?

* Basically I need to send a single "value/string" and have that data save into a PHP var when calling the php script. Is this possible with 3DGS? Does anyone have any information on why the data setting keeps coming up empty?
