I wrote a parser tag that displays some user options that are set in
Special:Preference. It gets embedded in an article like this:
<mystuff/>
However, when users change their options, my parser tag appears still displays
old, cached data. I have tried everything I can think of to stop this caching:
static function myHookFunction($input, $args, $parser) {
$parser->disableCache();
global $wgEnableParserCache, $wgCachePages, $wgParser;
$wgParser->disableCache();
$wgEnableParserCache = false;
$wgCachePages = false;
...
}
But all of this has no effect. The only way to get the new data to appear is
to edit the page or use ?action=purge.
Coincidentally, I have another extension that displays the same data (not using
a parser tag, but an ordinary callback via $wgHooks['OutputPageBeforeHTML']),
and the data is always up to date.
Both extensions use User::newFromName($username) to obtain User objects, and
$user->getOption() to get the values. But I don't think the User class is
causing this. When I make code changes to my parser tag, I don't even see the
results of the changes until I edit the page or use ?action=purge.
We are not running any other external caches at the PHP or web level.
What am I missing?
Thanks,
DanB
