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.
it has already been installed in the current database (by looking
for all the main tables) and do the right thing. It doesn't matter now
if there are other tables in the database or not.
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.
I've changed htmlentities to htmlspecialchars in this file, to fix
bugs with editing multibyte languages (ie Japanese). Please be
cautious and let me know if this causes any problems when editing
your language (it shouldn't, but I don't want to spoil your day!)
exposes the wide array of authentication possibilities.
Authentication now has it's own page separate from other variables.
Most of this work was done by Petri Asikainen <paca@sci.fi>, who started
these changes off.
I've done some cleanups and additions which is why I'm checking it in.
It's all working pretty well at the moment but could use some testing.
Thanks, Petri! :-)
