The flag has a memory, but it keeps pushing you to subscribe. :-)
(so that by default it behaves like it did before)
Hopefully now subscription is a bit easier to understand.
Firstly, I'm replacing all use of old-style global variables like
$HTTY_REFERER with their new-style equivalent $_SERVER["HTTP_REFERER"]
Also using $_POST instead $HTTP_POST_VARS etc
Secondly, if gdversion == 0 (ie GD is not installed) then:
- users are not even allowed to upload new images
- graphs now just print a message instead of failing.
this allows Moodle to still be used even if GD is not present
Should be fixed now. As a bonus, I've removed all the uses of
HTTP_POST_VARS from all scripts.
All forms should use the new data_submitted() function to collect
form data (it does the match_referer thing internally now).
Much nicer.
Moodle tables.
ie user -> userid in many tables, plus in user_students
start -> starttime and end -> endtime
I've just done all this as carefully as I could ... I don't think
I missed anything but it's pretty intensive work and I'd be fooling myself
if I didn't think I'd missed a couple.
Note that this version should pretty much be able to bootstrap itself
using PostgreSQL now ... but this is untested
Basically all the Database functions are in lib/datalib.php
and the web functions are all in lib/weblib.php, so
moodlelib.php is much thinner than it was.
Data functions have been extended ... most old calls will
still work, but now many more SQL commands can be performed
using the datalib functions rather than using SQL. I'm
currently moving through the whole tree replacing SQL
calls or at least concentrating them in one section of
mod/xxx/lib.php
Still working on forums, quizzes, surveys, resources.
The tree is currently not full working ... some things are
half-completed ... will resume tomorrow.
They are stored in the course moddata area.
They appear as links within the message, including mailed-out messages.
They are deleted when the post is deleted.
servers that have register_globals turned off (this is the
default setting on newer version of PHP).
In fact it's partly a hack that globalises all GET, POST, FILES
AND COOKIE variables. Unfortunately though the SESSION and
USER global session variables are only available as $_SESSION["USER"]
and $_SESSION["SESSION"], which is cumbersome to use.
So, for every request I now make a copy of these two session variables
into $USER and $SESSION. Whenever I update them thoughout Moodle I
now have to call save_session("USER") which copies them back to the
session variable. This seems to be working well now.
Because I'm using $_SESSION etc now this will raise
the required minimum version of PHP to 4.1.0
Basically the changes are:
- I've merged the 'discuss' module into the forum module
which makes the interface MUCH clearer for everyone
- I've added a new 'single' forum type that replicates
what the old discuss course modules used to look like.
- I've got rid of the "discussion" forum type - it will
still exist in upgraded courses but as a normal forum.
- the 'discuss' module is completely deleted - gone.
- the 'chat' module is completely deleted - gone.
- The upgrading system has been improved, and all code
is stored in version.php.
- I've put in upgrading commands to do the best I can
(right now) to upgrade courses that used the discuss
module. It should mostly work, just leaving some
"orphan" coursemodules on you course front page. You
can easily delete these using the little 'x'.
I may have forgotten something - I've only tested on
my testing server and I'm about to test on my production
server to see how it goes.
- Forums have a lot of little new features and fixes. The
main one is the subscription process. Teachers can 'force'
subscriptions on any forum. This disallows everyone from
choosing their own mail subscription - it's just on.
- The assignment module is half-finished and not working yet
I've still some massive changes to do, mostly involving making
all the lib.php function names more standardised, so consider
this is an interim checkin to do some tests.
