[OpenLayers-Users] Pass parameters to mapfile

[Arnd Wippermann]

Hi,

If you have declared the variable user_id before mergeNewParams, it should
also work. 

Because it is a Mapserver question, try and manipulate the request in the
browser and see what MapServer returns. If you get the response, you want,
then it is possible to get it also with OpenLayers.

Hi,

One issue remains still ..

"http://gis.rtbi-iitm.in/cgi-bin/mapserv?map=/var/www/html/customisation/map
file/customNR.map&userid=2"

is working ok with

DATA "the_geom from ( select * from customised_poly AS f where f.subcat_id
IN (select subcat_id from subcat_info where maincat_id =0) AND
user_id='%userid%' )AS foo1 USING UNIQUE gid"

but is I want to pass a dynamic value( a variable user_id) instead of a
number ( in this case 2) then its not happening .

I am still trying with wms[5].mergeNewParams({userid:user_id}) but its not
working yet  


Thanks,
Reena.
