[OpenLayers-Users] Pass parameters to mapfile

Mon Nov 10 05:22:14 EST 2008

Reena,

As per my understanding, I assume you want to pass dynamic value in the URL.

Can you try defining like the way I have done below:-

wms[5] = new
OpenLayers.Layer.WMS.Untiled("Customization","http://gis.rtbi-iitm.in/cgi-bi
n/mapserv?map=/var/www/html/customisation/mapfile/customNR.map&userid="+
user_id,{'layers':
'NR_point,NR_polygon,NR_line','transparent':"true"},{'isBaseLayer':false} );

Let me know if this solves, else go under OpenLayers.Layer.WMS.Untiled class
and try and find out what URL is being passed. You might have to use the
library files.

Thanks,
With Regards,
BIJOY K. ANUPAM

Hi,

I already tried with 

 wms[5] = new OpenLayers.Layer.WMS.Untiled(

"Customization","http://gis.rtbi-iitm.in/cgi-bin/mapserv?map=/var/www/html/c
ustomisation/mapfile/customNR.map&userid=2",{'layers':
'NR_point,NR_polygon,NR_line','transparent':"true"},{'isBaseLayer':false} );

It works fine with static value but not with dynamic values like
userid=user_id...

I think you were trying to suggest this only and if not then plz let me
correct myself...

Thanks,
Reena.
