[Mapserver-users] Polygon hilite

[Mark Balman]

Hi list

Firstly I would like to say what a fantastic forum....and thanks Chip for
helping me (months ago!) with the mapscript HOWTO example, which resulted in
me being really stupid.. I initially called the file test.html which just
produced a dump of php... renaming the file to test.phtml produced the
desired result e.g. a simple map... 

Recently I have finally managed to get my prototype application (built using
MapLab) to zoom to a polygon from a text input box using mail archive
suggestions from Paul Spencer and Andreas Berweger as follows :).
Unfortunately this is not "on-line" yet and is sitting on my laptop until I
can get the go ahead to put this on a server.. (could be weeks but more
likely months away : (   )

My problem:

In my test.php file in apache\htdocs\maplab\projects\gmf_apps\test I have
placed:

if ( $http_form_vars["SpeciesName"])
{
$szSpeciesName = $http_form_vars["SpeciesName"];
$oExtents = $oMapSession->oMap->extent;
$oldExtents=$oExtents;
$oSpeciesLayer = $oMapSession->oMap->getLayerByName( "range" );
$oSpeciesLayer->set( "filteritem", "SPCSPECIES" );
$oSpeciesLayer->setFilter("\"$szSpeciesName\"");
$oSpeciesLayer->queryByAttributes( MS_MULTIPLE );

if ($oSpeciesLayer->getNumResults() > 0 )
{
$oResult = $oSpeciesLayer->getResult( 0 );
$oSpeciesLayer->open($oMapSession->oMap->shapepath);
$oShape = $oSpeciesLayer->getShape($oResult->tileindex,$oResult->shapeindex
);
$oExtents = $oShape->bounds;
$oShape->free();

My mapfile contains:

END

What I cannot understand is how to return the result hilighted :( 

Although I could achieve this using mapserver CGI. In my init.html file I
have the following:

<form method=GET action='/cgi-bin/mapserv.exe'>
<input type="hidden" name="map"
value="c:\apache\apache\htdocs\world\world.map">
<input type="hidden" name="qlayer" value="ranges_region">
<input type="hidden" name="mode" value="itemnquery">
<input type="hidden" name="item" value="SCINAME">
<input type="hidden" name="program" value="/cgi-bin/mapserv.exe">
<input type="hidden" name="map_web_imagepath"
value="c:\apache\apache\htdocs\world\tmp\">
<input type="hidden" name="map_web_imageurl" value="/world/tmp/">
<input type="hidden" name="mapext" value="shapes">
<center><input type="submit" value="Initialize"></center>
Select a species distribution:
<select name="value" size="1">
<option>Accipiter brachyurus
<option>Accipiter butleri
<option>Accipiter gundlachi
<option>Accipiter imitator
<option>Accipiter luteoschistaceus
.
.
</select>
</form>
</body></html>

with my map file as follows:

#map
  name world
  status on  
  size 600 600  
  extent -180.0 -90.0 180.0 90.0
  units dd

Could anyone enlighten me as to what I am missing? Many thanks in advance
