In that case this should work:
VALIDATION
'county' '^[0-9]{1,2}$'
END
This limits county to a 1 or 2 digit number.
Note you'll get better performance using a plain string expression, e.g.:
CLASSITEM 'county'
CLASS
EXPRESSION '%county%'
...

Subject: [mapserver-users] Run-time Substitution
Dear anyone willing to help,
I'm having a hard time interpreting how to properly execute runtime cgi
variable substitution using an <input> of type=text.
If I replace '%county%' with a sample county attribute value in single quotes
the EXPRESSION works and is displayed on the returned html template.
Currently my html input variable in the template looks like this :
<input type="text" id="county" name="county" />
...and my mapfile variable to be substituted for looks like this:
LAYER
NAME blah_ohio
STATUS OFF
TYPE POINT
DATA BLAH/BLAH_Ohio
PROJECTION
"init=epsg:3754"
END
CLASS
NAME 'Class1'
EXPRESSION ('[County]' eq
'%county%')
STYLE
SYMBOL "circle"
COLOR 250 50 50
OUTLINECOLOR 0
0 0
SIZE 2
END
END
METADATA
"wms_title" "blah_ohio"
"wms_srs" "epsg:4326"
END
END
Thanks in advance,
Paul
