[mapserver-users] Parameter substitution problem

[Steve Lime]

My guess is the validation is correct but the syntax of the URL parameter is
is wrong in that the value passed for DATA is not quoted. If you unquote the
default value in your mapfile does that result in a error? That would be an
easy way to test the need for quotes.

One last idea, while map_layer... should work, try map.layer... instead as
you variable name.

If you're really are just replacing the date part you could do that by doing
a runtime sub...

 DATA "OMI-Aura_L3-OMCLDRRclpWMSNRT_%date%.png"
 VALIDATION
     date 'regex'
 END

And then you pass date as a CGI variable.
