Actually I am having the same issue with this runing with a PHP script. I tried a code I found online that was along the lines of:
on (release {
myVars = new LoadVariables();
myVars.userName = userName.text;
myVars.password = password.text;
myVars.loadAndSend( "http://www.blahblah.com/blah.php", myvars, "POST");
}
and then the PHP script would be looking to receive two variables, userName and password.
