[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%'
