[Mapserver-users] MapFile - DATA question

[Steve Lime]

I've only done it in testing and it does work just fine. However, this
feature is also a
source of concern from a security perspective, that is, allowing a user
to arbitrarily
change that data being processed. So, for versions 3.7+ there are
restrictions in place
to disable this functionality unless you explicitly need it. See the
following page on the
wiki for more details...

Look for the section on DATAPATTERN and TEMPLATEPATTERN.

Hi!!!
Has anyone modified the DATA tag through the mapserv cgi params?
or the question would be: It is possible to change the DATA tag using 
mapserv cgi params?

In this example, we modified the 'map size' property.

http://localhost/cgi-bin/mapserv?map=/var/www/html/ews/v0.7/files/map/m4.map&mode=map&map_size=450+600


We would like to change the 'DATA' property along diferent calls.
For example:

time 0:
data='the_geom from table1'

time 1:
DATA='the_geom from table2'

time 2:
DATA='the_geom from table2 where population > 100000'

etc.

Thanks in advance.

Ariel
