[mapserver-users] Run-time substitution

[scott159 at free.fr]

Hi,

I would like to use run-time substitution in a mapfile to insert variables like %firstname%.
Is it necessary to specify validation block in the mapfile to use it ? It doesn't work without this validation pattern.
Second problem, how to specify this validation pattern to use characters with accent like 'é, à'. I try this example but it doesn't work :

VALIDATION
  'firstname'     '^[a-zA-Zéà\-]+$'
END

Thanks a lot
