I see no problem with it.<br>
The filter is bascially an SQL statement, so you can try changing the
URL to:<br>
<a moz-do-not-send="true"
href="http://localhost:8008/mapguide/test/KMLContentFactory.php?FILTER=%22.urlencode%28$_GET%5B%22PropertyName">http://localhost:8008/mapguide/test/KMLContentFactory.php?FILTER=FID>0</a><br>
<br>
Where FID is an existing numeric column.<br>

<div style="font-weight: normal;">You should provide more surrounding
code, or say where the code is from.<br>
In the code below, the envelope is never used, so it doesn't matter if
it is there.<br>
I assume it was supposed to be combined with the attribute filter like
this:<br>
if ($queryEnvelope != null)<br>
$queryOptions->SetSpatialFilter($queryEnvelope)<br>
