Re: [mapserver-users] Can the PROCESSING layer attribute be set dynamically through (PHP) MapScript?
Hi Dan, Yes I only just saw that you can load layer definitions from strings. This would be indeed much less cumbersome than using mapscript. We'll have a look at this for our next project/. Thanks for your input!

You might want to reconsider how your script is built. Instead of loading up the Mapfile and tweaking small parameters with MapScript, consider converting your mapfile to a template language. This way you can forumulate the mapfile, load it as a string, do the appropriate substitutions, then use PHP to serve it as WxS. This usually ends up being faster, easier to maintain, and more flexible over the long term.

Re: [mapserver-users] Can the PROCESSING layer attribute be set dynamically through (PHP) MapScript?
Hi, It would be easier to play with PROCESSING attributes if they could be changed with runtime substitution. Thomas Bonfort has written that any favorite MapServer provider can do the addition. http://lists.osgeo.org/pipermail/mapserver-users/2013-September/075342.html -Jukka Rahkonen- Jorrit Goddijn wrote: Hi Dan, Yes I only just saw that you can load layer definitions from strings.
