Hello,<br><br>Don't know exactly your case but you can maybe rely on runtime substitution <a href="http://mapserver.org/cgi/runsub.html">http://mapserver.org/cgi/runsub.html</a> and spatial abilities of your database e.g <a href="http://postgis.refractions.net/docs/ST_Within.html">http://postgis.refractions.net/docs/ST_Within.html</a><br>

or on filter (support within <a href="http://mapserver.org/mapfile/expressions.html#spatial-expressions-that-return-a-logical-value-geos">http://mapserver.org/mapfile/expressions.html#spatial-expressions-that-return-a-logical-value-geos</a> ) + runtime substitution<br>

In all case, a bit dirty compare to SLD filter but no choice it seems.<br><br>Regards<br><br>ThomasG<br>
