[mapguide-users] Problems using concat for URL Parsing

Thu Mar 13 21:18:20 EDT 2008

URL in Mapguide: 
concat('../central_plant/sensors/send_Id.php?DeviceID=',
concat("thermostat_id", concat('&DeviceType=', concat("type_d",
concat('&PrimaryIndex=', "PRIMARYINDEX")))))

Yes I do. I get this:

array(3) { ["DeviceID"]=> string(1) "1" ["DeviceType"]=> string(10)
"thermostat" ["PrimaryIndex"]=> string(1) "1" }

Which means that the script received the attributes properly, right? In that
case what's wrong with the rest of the code?

<?php

	$DeviceID = $_GET["DeviceID"];
	$DeviceType = $_GET["DeviceType"];
	$PrimaryIndex = $_GET["PrimaryIndex"];	

?>
<html>
  <head>
    <script language="javascript" type="text/javascript">
      function OnPageLoad()
      {
       		parent.parent.mapFrame.Refresh();
      }
    </script>
  </head>
<body onLoad="OnPageLoad();">

<script language="Javascript">

		var Device_ID = <?= $DeviceID ?>;
		alert (Device_ID); //displays ok
		var PrimaryIndex = <?= $PrimaryIndex  ?>;
		alert (PrimaryIndex); //displays ok
		var Device_Type = <?= $DeviceType ?>;
		alert (Device_Type); //fails to display
		alert (PrimaryIndex);

</script>
</body>
</html>

Thanks Jackie.
