I've upgraded my MW installation and the extensions, but the problem
remains. I would guess it's to do with passing references vs values, or
there is some MediaWiki-specific thing that I am not aware of.
Perhaps someone can help me sort out the syntax for writing an event
handler that modifies an existing value.
Here's where the hook is called:
wfRunHooks( 'CiteBeforeStackEntry', array( &$str, &$key, &$call ) );
Here's the hook:
$wgHooks['CiteBeforeStackEntry'][] = 'wfProcessCite';
Here's the function:
function wfProcessCite( $str, $key, $call ){
...
I want to change the value of $str, but leave $key and $call unchanged.
Can someone indicate the correct syntax?
Thank you!
Amelia.
