Hi Josh,
this is funny! I've hit this bug while working on a KML export, too.
I've extracted a minimal test and it is attached to
http://trac.osgeo.org/mapserver/ticket/3406.
Regards,
Peter

I think I came across the same thing, or something related, when I was
trying to generate KML using mapserver templates. I know I ended up
recreating the class expression in my output instead of using the
[shpclass] variable. Let me know if a bug is filed and I'll work up an
example to submit. (mapserver 5.2)

Hi Peter,
If you are sure that the shape use the different classes you specified in the
mapfile (you probably see it in your map image), so I guess it could be a bug.
Please fill a ticket with a test case. Assign it to "aboudreault".
regards,
Alan

Hello
As I interpreted this, classindex should point to the right class of the
instantiated shape. Unfortunatly, classindex is always 0.
As a test I have a LAYER with 2 classes,
CLASS
NAME 'class1'
EXPRESSION (([class] eq 1))
STYLE
SYMBOL "circle"
SIZE 7.0
OUTLINECOLOR 0 0 0
COLOR 0 128 0
END
END
CLASS
NAME 'class2'
EXPRESSION (([class] eq 2))
STYLE
SYMBOL "circle"
SIZE 7.0
OUTLINECOLOR 0 0 0
COLOR 0 0 128
END
END
In the PostGIS database are 4 point, 2 with class=1 and 2 with class=2,
the generated map image shows the expected colors.
The following script:
<?php
$mapfile = 'test.map';
$map = ms_newmapobj($mapfile);
$layer = $map->getLayerByName('test');
$status = $layer->open();
$status = $layer->whichShapes($map->extent);
while ($shape = $layer->nextShape())
{
echo "index: {$shape->index}\tclassindex: {$shape->classindex}\n";
}
$layer->close();
?>
the following output:
index: 0 classindex: 0
index: 1 classindex: 0
index: 2 classindex: 0
index: 3 classindex: 0
which is not what I expected.
Am I missing something obvious or is this a MapServer bug?
Regards,
Peter
