Which binaries are you using?
If you your own custom build then are you sure it's not a case of
multiple versions of REGEX on the same system? That used to be a problem
in the old days with PHP's local copy of regex conflicting with the
system regex, but I don't think that is a problem any more though.

Well, that’s not good is it. Hmmm… I ran a quick test here using this
mapfile:
MAP
NAME 'test'
SIZE 450 600
EXTENT 125000 4785000 788000 5489000
IMAGETYPE PNG8
LAYER
VALIDATION
'area' '^[-+]?[0-9]*\.?[0-9]+$'
END
NAME 'county'
STATUS DEFAULT
TYPE POLYGON
DATA ' bdry_counpy2'
CLASS
EXPRESSION ([area] > %area%)
STYLE COLOR 212 212 212 OUTLINECOLOR 0 0 0 END
END
END
END
This is against 6.0 latest trunk although I don’t think there have been
any changes in that area…
I can run something like:
mapserv -nh "QUERY_STRING=map=test.map&mode=map&area=500000000" > test.png
If ‘area’ parameter is provided as a non-double then the substitution
isn’t done. I believe the substitution validation errors fail silently.
This example works, how different is what you’re doing?

Thanks Steve.
Tried the following regular expression
"[-+]?[0-9]*\.?[0-9]+".
For which the internal server error is coming from Apache. No error
logged in mapserver log.
"Internal Server Error

*Subject:* [mapserver-users] Problem with Variable Substitution for
EXPRESSION
Hi,
I need to compare one attribute from database table in "EXPRESSION"
(under "LAYER") with six different values passed as Variable
Substitution for coloring the layer.
I did added validation for those variables in the map file, but for some
reason I am getting the below error.
*msValidateParameter(): Regular expression error. Parameter pattern
validation failed.*
*msEvalRegex(): Regular expression error. String failed expression test.*
*msValidateParameter(): Regular expression error. Parameter pattern
validation failed.*
Could anyone help me with where I am wrong? Below is the map file
content for this layer.
All the six variables would be numbers (may be a decimal number), Is my
regular expression correct?
WEB
VALIDATION
value_one "^[\d+(\.\d)]*$"
value_two "^[\d+(\.\d)]*$"
value_three "[^\d+(\.\d)]*$"
value_four "[^\d+(\.\d)]*$"
value_five "[^\d+(\.\d)]*$"
value_six "[^\d+(\.\d)]*$"
END
END
