checkdir.php

I am having an issue getting the checkdir.php to pop up a window on connect.

function custom_popup($ALLVAR) {

    // For Asternic Tag Call
    if($ALLVAR['poptype']=="ringing") {

        // RINGING NOTIFICATION

    } else {

        // AGENT CONNECT NOTIFICATION

        $clidnum   = $ALLVAR['clidnum'];
        $clidname  = $ALLVAR['clidname'];
        $fromqueue = $ALLVAR['fromqueue'];
        $exten     = $ALLVAR['exten'];
        $clidname = base64_decode($ALLVAR['clidname']);
        $clidnum  = base64_decode($ALLVAR['clidnum']);
        file_put_contents('/tmp/popup.txt', print_r($ALLVAR, true));

        header("Content-type: text/javascript");
        echo "window.open('http://192.168.1.1/popup.php?callerid=$clidnum&name=$clidname&queue=$fromqueue&agent=$exten')";

    }

    return 0;   // We do not want regular notifications
}

I am getting the debug contents in my /tmp/popup.txt

Array
(
    [poptype] => connect
    [clidnum] => MTUxMzMyODg0MzY=
    [clidname] => TnVyc2U6Q2VsbCBQaG9uZSAgIE9I
    [exten] => 2004
    [fromqueue] => Nurse 302
    [UNIQUEID] => 1479837388.2057
)

NOTE: [fromqueue] is showing the Queue's LABEL (as defined in the button config) , is there a way to get the Queue's Extension instead

[QUEUE/302]
type=queue
Label=Nurse 302
Extension=302
context=from-support-srvcs

NOTE: that the cidname and num have not been decoded as they are a print out from the $ALLVAR[] array

I was hoping that this would pop up in my minibrowser plugin like when i add the popup url to the preferences section.

http://192.168.1.1/popup.php?callerid=#{CLIDNUM}&callername=#{CLIDNAME}&UNIQUEID=#{UNIQUEID}&QUEUE=#{FROMQUEUE}&AGENT=#{EXTEN}

I switched from adding the info in the fop panel preferences URL POPUP because I am unable to get the Extension number that took the call to be passed and i need to be able to pass that to my popup.php

here is the output i am getting when using the popupurl in preferences
Array
(
[callerid] => 18885551212
[callername] => Nurse:Cell Phone OH
[UNIQUEID] => 1479837733.2063
[QUEUE] => Nurse 302
[AGENT] => undefined
)

As you can see in this example there is no EXTEN variable getting saved.

Not sure where to go from here debug wise.
