Detailed Description

-

Arbitrary configuration storage.

-

Note: Please do not store booleans - convert to 0/1 integer values The get_?config() functions return boolean false for keys that are unset, and this could lead to subtle bugs.

-

Arrays get stored as serialize strings.

-

Todo:: There are a few places in the code (such as the admin panel) where boolean configurations need to be fixed as of 10/08/2011.

-

config is used for hub specific configurations. It overrides the configurations from .htconfig file. The storage is of size TEXT.
pconfig is used for channel specific configurations and takes a channel_id as identifier. It stores for example which features are enabled per channel. The storage is of size MEDIUMTEXT.
$var = get_pconfig(local_channel(), 'category', 'key');
-
xconfig is the same as pconfig, except that it uses xchan as an identifier. This is for example for people who do not have a local account. The storage is of size MEDIUMTEXT.
$observer = $a->get_observer_hash();
-
if ($observer) {
-
$var = get_xconfig($observer, 'category', 'key');
-
}
-

-

get_config() and set_config() can also be done through the command line tool util/config
get_pconfig() and set_pconfig() can also be done through the command line tool util/pconfig and takes a channel_id as first argument.
