I've added the variable CFG->main_frame to config-dist.php, and replaced _top
targets with the variable in all the php files. HTML files, like those in the
documentation, have not been modified, as they are not (yet) parsed.
The variable should probably get moved into the config table, and get some
documentation.
I've also included, but commented out, a slight change in weblib.php, which
would guarantee that messages would be seen before redirecting the user (unless
delay intentionally set to 0 when redirect is used).
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.
If true, then display of user pictures or filenames will use the
method of providing arguments as "slash" arguments - this is much
better for caching, proxies, search engines etc. Unfortunately
it doesn't seem to work on some PHP installations.
If false (the default), then a more compatible method is used
(ie usual way of passing parameters to scripts)
rely on the administrator to tell us which is installed because PHP
is not reliable (eg GD 2.* functions are available in 4.0.6 and later
EVEN WHEN gd 2 is not present ... sigh).
So, new config variable $CFG->gdversion
