[mapguide-users] Suitable Database for MapGuide using FDO

[Paul Spencer]

Krunoslav, I don't think this is a particularly fair set of comments  
to make.  Everyone has to start somewhere, and in open source we  
(should try to be) particularly friendly to new users and help them  
out.  In some cases, a little research is in order before coming to  
the list (that is what FAQs are for).  I think this particular  
question is valid for someone new to MapGuide OS.  New users become  
experienced users and can help out ...  Also new users tend to ask  
the 'obvious', 'dumb' questions that force you to think about things  
in a different way and often improve a project :)

Dhirendra, MapGuide provides a rich API for editing feature sources  
under MapGuide's management.  SHP and SDF files can easily be updated  
if you are willing to spend some time learning the Feature API.

For your case, I would build two applications that point to the same  
map.  The first would be public facing and just provide a view of the  
data.  The second would be for entering new information into the  
voting data source.  You can create a PHP page as a custom task and  
add it to an application.  The PHP page would have (at least my first  
idea of how to do this) a form with an input that is populated from  
the voting station names and a series of input values that allow you  
to enter in new values for each of the fields (i'm guessing number of  
votes per candidate or something like that).

The psuedo code would look something like:

open map from session
get voting layer from map
get feature source id from voting layer
if form was submitted:
   get feature id from form variables
   get field values from form variables
   create new MgUpdateFeatures
   execute MgUpdateFeatures
   force refresh on voting layer
output form header
output voting station select:
   open feature source id
   select all features
   loop over features:
     output option with value = feature unique id (required above)  
and station name
close form

You could also output javascript and arrays of voting stations by  
region and have two selects, one for regions that updates the voting  
station select with the appropriate values if you have a lot to manage.

Cheers

Paul
