[GRASS-user] exwcuting grass python script from php web page

[roberta fagandini]

Hi all!
I wrote a python script with grass to be run from a php web page.
The python script works perfectly if I run it from the terminal but when I try to run it from the php web page, the grass related part seems to be ignored and the grass session is not launched. I set the grass gis environment following this link [0].
>From the php side, I try to launch the python script using both exec(), system() and also a bash script to run the python script but I always got the same error.
Attached you can find the python script.

Does anybody have any ideas on how to fix it?

Thanks in advance for the help!
Roberta

GRASS sessions. It is possible to access GRASS modules without explicitly starting a "GRASS session". GRASS libraries require certain environment variables to be set. In fact a "GRASS session" is just a set of processes (e.g. a shell and/or GUI) which have the necessary environment settings, specifically:
