I am hacking an existing extension, ProcessCite, that integrates into the Cite extension by adding a custom hook to one of Cite's functions: # from Cite_body.php function stack( $str, $key = null, $group, $follow, $call ) { # add the call to the CiteBeforeStackEntry hook wfRunHooks( 'CiteBeforeStackEntry', array( &$str, &$call ) ); ProcessCite runs code that creates a value for $str based on the contents of $call. Here are the relevant parts of ProcessCite: # Declare the hook: $wgHooks['CiteBeforeStackEntry'][] = 'wfProcessCite'; # the function itself function wfProcessCite($str, $argv){ # process $argv and $str to create a new version of $str # $argv remains unchanged, $str is set to new value $str = "new string"; return true; } Debug statements reveal that wfProcessCite is creating the correct value for $str, but the value is not altered when wfProcessCite finishes. I am not sure if I am calling the hook in the wrong way, given that I want to alter the value of $str. The MW manual page on hooks (http://www.mediawiki.org/wiki/Manual:Hooks) is somewhat confusing -- what is the difference between passing $someData to a function versus passing a set of parameters?! Any help would be appreciated!
