Hi Steve,
We were able to implement the lines and polygons already...it was a big
help. Thanks!
Now we have a problem regarding passing multiple values from mapserver to
openlayers.
We have tried this:
e.g. ...&foo_value=value1 value2&...
but with no avail.
We are trying to implement thematic mapping and routing functionalities for
the map.
I hope you can enlighten us on this.

Hi Aileen: The direct setting of class expressions using via the syntax
you're trying is no
longer supported. It's not possible to apply any validation rules in this
case. There is a work
around using runtime substitution though. For example, if your mapfile looks
like this:
LAYER
NAME 'foo'
...
CLASS
EXPRESSION '%foo_value%'
...
END
END
Then you can set the expression like so:
...&foo_value=makati&...
You can also validate the input using a regex, just add a metadata block
like this to the layer above:
METADATA
# allow foo_value to be a string 1 to 10 chars in length, no special
characters
foo_value_validation_pattern '^[a-z]{1,10}$'
END
This applies to FILTERs as well.
The syntax to change a class color is documented in the examples you've
already seen.

Subject: Mapserver 5 and Openlayers 2.5 passing of parameters.
Hi all,
We are currently using the latest release of Mapserver, the 5.0.2 version
and Openlayers 2.5
We are having problems with rendering lines and polygons because
although
it worked for us in Mapserver 4.10, we are told that there's a new
syntax
for passing values to mapserver.
Currently, here's part of the url that we are using to pass to
mapserver:
map_layer_class_expression=makati&map_layer_class_color=255 0 0.
We already have looked at your samples but with no avail.
Can you help us with the new syntax?
