generateSLD returns an empty SLD

[Gilles Bassière]

Hi list

I try to use the generateSLD method but can't get it to work.

I have the following code (adapted from Mapserver how-to) :

<?php

// define variables
define("MAPFILE", "/home/gba/public_html/and/test.map");
define("MODULE", "php_mapscript.so");

// load the mapscript module
if (!extension_loaded("MapScript")) dl(MODULE);

// open map
$oMap = ms_newMapObj(MAPFILE);

foreach ( $oMap->getAllLayerNames() as $layerName )
{
   $oLayer = $oMap->getLayerByName($layerName);

   // generate the sld for that layer
   $SLD = $oLayer->generateSLD() ;

   // return SLD to client
   echo $SLD ;
}
?>

I have several layers which are very simple and all look like this one :

   # LAYER golf -------------------------------------
   LAYER
      NAME             "golf"
      GROUP            "background"
      CONNECTIONTYPE   postgis
      CONNECTION       "host=localhost dbname=test user=test 
password=xxx port=5432"
      DATA             "wkb_geometry FROM golf"
      STATUS           off
      TYPE             polygon

      CLASS
         NAME          "Golf courses"
         STYLE
            COLOR      203 216 195
            ANTIALIAS  true
         END
      END

      PROJECTION
         "init=epsg:4326"
      END

      METADATA
         "wms_title"   "Golf courses"
         "wms_srs"     "EPSG:4326"
         "wms_extent"  "3.3 50.75 7.25 53.6"
      END
   END

The PHP script above returns the following output :

This output is a valid SLD, I agree... But I expected to find the 
parameters set up in the CLASS element, how should I proceed ? What is 
going wrong there ?
