Hi smile

I am beginning to code my groupware module for moodle, and I have been going through the code trying to find out how to obtain information about the current course, user, instance of my module etc.

I have got as far as:-

course->id = ID of course user is in
groupware->id = ID of Instance of my module user is in

But I require some other information like the ID of the current user etc...

Is there a particular file I should be looking in for this information? I have looked in moodle, datalib etc, but cannot find the right information.

I am presuming there are some class files that I can look through to find out the
data the classes store? There seems to be an instance of a course and groupware class I can read information from, is there also an instance of the user class for the current user?

Many thanks,

Chris.

Update smile I found the user object, it was USER, capitalised smile

I got this from line 23 of the index.php file for the main site:-

if (empty($USER->id))

Any guidance about where to find these things without hunting through code would be fantastic.

Many thanks,
chris.

The coding guidelines will be helpful to you I think. smile

There are four global environment objects:  $CFG, $SESSION, $THEME and $USER

Thanks Martin. I was following these, but these globals were presented as something not to extend, not something people should use. Though as a PHP programmer, I should I suppose have simply seen these and print_r'd them to find out more.

Aside from the wiki, where is the best place I can contribute more developer documentation to? or is this wiki the right place? it seems to be infrequently updated, so I wondered if some other document repository has superceeded it?

Many thanks,

Chris.

Please keep asking questions Chris.  Although I have not posted before, I am learning a lot watching this thread and the other threads about your project.

Are you developing a new module as well? I've found it difficult to get into, but now have most of the answers I need I think. I will produce some developer docs to further help new module developers soon.

If you think I can answer any questions to you, as someone who has now suceeded in creating a basic module, please post, and I'll reply.

Many thanks,

Chris.
