if you use UPDATE HTTP method to call your script $_POST won't work.
You can do something like that:
$rest = $_SERVER['REQUEST_METHOD'];
if(isset($_SERVER['CONTENT_TYPE'])) {
$content_type = $_SERVER['CONTENT_TYPE'];
}
if ($rest=="PUT") {
$body = file_get_contents("php://input");
parse_str($body, $parsed);
switch ($content_type)
{
case "application/json":
// do stuff
break;
case "application/x-www-form-urlencoded":
// do stuff
break;
}
break;
}
}
Or use POST
