Hi,
I had thought of trying that but the attributes in the values are
read-only. Since i created the shapeObj from WTK there are no values.
I'm using v7 of MapServer and the old PHP mapscript. There does not
appear to be a way for me to set attributes on these shapes which are
being passed down from an OpenLayers client app.
I had thought of setting a single class and putting the different
colors, etc, in as attribute values in the shapeObj but cannot find a
way to write them to the object.
I'll try any suggestions given.
Thanks,
*Worth Lutz*

Hi,
The rendering code could be reassigning the classindex for the shapes
based on their attributes. You will probably need to make sure the
CLASS is assigned based on an attribute of the feature - e.g. add a
CLASSITEM to the layer and add a value to the feature that will match
the correct CLASS.

HI,
I'm trying to create a layer to insert into a map. I have shapes in
WKT and am trying to insert them into a layer and draw it to a pdf.
It works fine if I only have one class for the shapes. I am trying to
add several classes to the layer to draw in different colors. I
cannot get the shapes to use the proper class.
Here is what I'm doing.
After creating a layer and adding all the classes, I add the shapes.
for (i = 0, ii = count($features); $i < $ii; i++) {
$shape = ms_shhapeObjFrom Wkt($features[$i]->geometry);
$shape->set('classindex', $features[$i]->classindex);
$success = $layer->addFeature($shape);
}
The shapes draw but all use $class[0].
If I add this line in before the draw,
$layer-moveclassup(1);
all the shapes are drawn with that class.
I have been able to verify that the classes exist in the layerObj and
that the classindex in the shapeObj points to the proper class.
Does anyone have any ideas why the drawing code is not using the
classindex to draw these shapes in different colors?
What am I doing wrong?
