[Mapserver-users] Perl Mapscript - render shapefile with no m ap

[Simpson, Andrew]

What I'd like to do is render a map using Perl mapscript only, without
static or dynamic map files, and without stepping through the shapes.
I know I should just go with one of these two work arounds, but the code to
do this seems to be available and I would like to avoid the overhead of
creating/deleting map files.

Thanks for your reply,
Drew.

P.S. Sorry for the double post, I had E-Mail alias problems.

I may be missing the question but:
What you are trying to do does work.
If you dynamically create a mapfile and include a 'place-holder' layer
definition and then set the $layer->{data} on the fly it does work.
Being that you are trying to set the $layer->{data} dynamically does that
mean you are trying to set the 'data' to a shapefile that was just created?
If so you will want to make sure that the data.shp has a corresponding
data.dbf file to go with it or the $layer->{data} = 'data' will fail.
