[mapserver-users] Mixed Mapfile and Mapscript (php)

[Lowell Filak]

It's not a php example, but there are perl examples of adding points & shapes to a layer at:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35ex2
&
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35ex9
Possibly you can use those to at least decode the steps required.
One other thing to check is - if you are creating a dynamic shapefile (which doesn't appear the case from the code) be sure that the dbf file to go with it is created also.
