[mapserver-users] PHP MapScript: shape->classindex is always 0

[Peter Hopfgartner]

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
