Added $user->theme and $course->theme choices, controlled by admin
variables on the main config variables page.
By default this is all turned off, since multiple themes can be
a little disorienting.
A hidden feature is session themes ... you can change the theme
on any page by passing theme=xxxx as a parameter. By default this
requires sesskey (so that people don't change theme on each other),
but this security can be switched off using a hidden variable
$CFG->allowthemechangeonurl = true; Good for quick tests.
If the admin specifies a Policy Agreement (via URL in the config variables)
then each user is required to see and agree to that document once before
continuing.
To get everyone to see it again (on an update, say) one just needs to issue:
UPDATE user SET policyagreed = 0
Default is false, everything is as it is now.
If turned on, then users are forced to log in before
being able to see the front page or the course listings.
OK, this is a big check-in with some big changes, and needs work still.
It seems relatively stable, but I need help identifying the rough patches.
1) First grading scales support. There is a now a new table called "scale"
that contains grading scales. There can be site scales (course=0) and
custom course scales. These can be used in modules - I've only done
forums for now but that was the hard one. Scales can be edited via
the new item in the course admin menu.
There is one default scale - the connected/separate knowing one that used
to be in forum. To build this I pull data from the language packs
to create one during the upgrade, or anytime a scales menu is called
and no scales are found.
2) New roles for course creator and teachers. I've fixed up the course
menus and some other things but there's a lot left to do on this to
make it all smooth. The idea is that teachers no longer can edit courses
unless they are also course creators. The interface for this needs to
be smoothed out a fair bit and I need help with this.
The upgrade will upgrade all teachers to be creators, but will default
the new site config "creatornewcourses" to "no", so that effectively
these new teachers have the same privileges.
3) Simplified teacher management. There is no longer an "assign teachers"
and a "teacher roles" page - it's all on one page in course/teacher.html.
Phew ... time for a shower and then back into it.
instead of external zip programs.
To use the internal PclZip, the config variables "zip" and "unzip"
must be left blank.
Code for PclZip integration originally from Robert Hetzel, though
I've expanded it and modified it a lot.
The zip files seem compatible with itself and Windows XP, but I had a
compatibility problem trying to unzip a PclZip file using Zip 2.3 on Linux
(directories are unpacked as empty files)
- rename the main_frame variable to framename, because it
- might have caused some confusion
- none of the global variables have underscores
- put the config in the config table, with a default of _top
