[mapserver-users] Layer Object Parameter Substitution fromURLusing GIS

[Steve Lime]

Hi Heiko: I'm thinking this is a problem with the snippet I sent you.
Because MapServer is
tokenizing the content of the VALIDATION block it's sees the word FILTER
as a keyword
that isn't allow in that block. The fix is to simply quote any
validation keys that are keywords
so the block becomes:

  VALIDATION
    'filter' '^orbitnr=[0-9]{1,5}$'
  END

I've tested on my end and things are ok.

Hello Steve,

Mapserver fails by just scanning the mapfile.
Did fetch the 5.4_rc1 and installed it. But same behaviour as with the 
5.4_beta.

/usr/lib/cgi-bin/mapserv -v
MapServer version 5.4.0-rc1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP 
OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=ICONV
SUPPORTS=WMS_SERVER 
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER INPUT=EPPL7 INPUT=POSTGIS
INPUT=OGR 
INPUT=GDAL INPUT=SHAPEFILE

[Thu Apr  9 08:13:06 2009].548952 loadHashTable(): Unknown identifier.
Parsing 
error near (FILTER):(line 128)
[Thu Apr  9 08:13:06 2009].549088 msFreeMap(): freeing map at 0x18c51b0.

Did cut and paste your filter suggestion into the Mapfile but same
result.
I'am back in the office on 15th of April.
Thanks for your effort.
Regards
Heiko
