[Mapbender-users] Digitizer : different color for the objects

[Astrid Emde]

Hello Gérald,

you can do this easily as you can use die OpenLayers 2 styles in the 
digitizer.

See OpenLayer 2 styles documentation: 
http://docs.openlayers.org/library/feature_styling.html

You should add a new column for the color in your table, that you fill 
depending on the choice of the user.

f.e.

Alter table poi add column color varchar;

As Mapbender does not support combo you could choose a selectbox  for 
the different types.

Add the selectbox to your digitizer configuration:

f.e.

             -
               type: select
               title: Type
               name: color
               options:
                 '#ff00ff': Type-A
                 '#00ffff': Type-B
                 '#ffff00': Type-C
                 '#00ff00': Type-D


Styles could look like this - with ${color} you refer to the new column 
with the color values

   styles:
     default:
       strokeWidth: 2
       strokeColor: '#0e6a9e'
       fillColor: ${color}
       fillOpacity: 1
       fillWidth: 2
       pointRadius: 10
     select:
       strokeWidth: 3
       strokeColor: ${color}
       fillOpacity: 0.7
       pointRadius: 10

Happy cycling!

Astrid
