where data from other modules can also live later on.
Also added a README for that directory to warn teachers not to mess
with it, version code to perform the upgrade, tweaks to assignment/lib.php
and a tweak to reading module so that assignment files aren't listed
in the list of possible readings (could get messy).
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
gmdate to format times, thus allowing it to take advantage of locale, if set,
to print dates in the appropriate language. Several userdate invocations
had to be changed, though, to use the different formatting specs.
