problem about the loadVariables example

[nanifrankey]

loadVariables("http://127.0.0.1:1001/Basic/uldl?klCommand=loadVariables&
klUrl=http://www.example.com/page/get.php?variable%201=value&klUrlDecodeOff=1",
"" );

in this examples, there is a string variable%201= value will be sent to server, I would like to send a Login Username to the server, how can I modify the code here?
change it to variable%201 = LoginName?
I am not quite understand here, it means a all variables in the page are included and will be sent to the server? or only one variable which is written here?
If it is only one variable, then I do not know what else error I have here.

In my server side, it shows following;
                            $Uname = $_POST['LoginName'];
or it has to be written like:
               if ($Uname = $_POST['LoginName']){$Uname = $_POST['LoginName'];}

is that ok?

I am very appreciating admin's help

variable%201=value
should be just variable=value

Example :
klUrl=http://www.example.com/page/get.php?LoginName=testuser

and PHP code :
$Uname = $_POST['LoginName'];

hope that helped
