[mapserver-users] Mapserver 5 and Openlayers 2.5 passingof parameters.

[Aileen]

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.
