Re: [mapserver-users] Runtime Substitution Not Working

[Helen San Segundo Navazo]

hi Ryan,
try to add the validation pattern inside the layer tag
METADATA
     'file_validation_pattern'    "[A-Z0-9._%+-|'\(\)]"
     'default_file'    "ultima_imatge" #-------> this is to give a 
value when you don't put the &file=value in the url call
 END

 VALIDATION
     'file'    "[A-Z0-9._%+-|'\(\)]"
 END

DATA '%file%'

Hi,

I'm trying to use runtime substitution to replace the DATA setting of 
the Mapfile at runtime.  I'm running in tile mode and using GRD raster 
format.

Here's the mapfile:

MAP

    NAME Blah2

    STATUS ON

    SHAPEPATH "C:/Contours/FSGrids"

    PROJECTION "init=epsg:26918" END

    LAYER

        NAME Contour

        TYPE RASTER

        STATUS ON

        DATA '%file%'

        CLASS

            NAME "Contour"

        END

        PROJECTION "init=epsg:26918" END

    END # Layer

END

And here is a sample request for one of the tiles that I've copied 
from Fiddler ...

http://<my 
server>/cgi-bin/mapserv.exe?map=C:/ms4w/Maps/mapfile2.map&file=Site_1_1_1_Total.grd&mode=tile&layers=Contour&tilemode=ve&tile=03023032203031 
<http://%3cmy%20server%3e/cgi-bin/mapserv.exe?map=C:/ms4w/Maps/mapfile2.map&file=Site_1_1_1_Total.grd&mode=tile&layers=Contour&tilemode=ve&tile=03023032203031>

If I put the filename directly in the DATA setting of the mapfile it 
works fine and I see the grid in Virtual Earth.  If I try to use 
runtime substitution to put the file name it just produces blank tiles.

Any help is very much appreciated, thanks!

Ryan
