Thread:Extension talk:InputBox/Hacked version that allows other wikis to be searched using the searchbox

Check out rationalwikiwikiwiki:WikiIndex. This page transcludes rationalwikiwikiwiki:Template:Wiki, which has an inputbox tag in it with  as a parameter. That tells it to look for |search URL= in the transcluded template. So, by putting |search URL=http://wikiindex.org/, that creates a search bar to search WikiIndex. This is implemented by a hacked InputBox.classes.php using some code borrowed from ChangeWikiaEngine.php (although I probably should have borrowed from Manual:Chris_G's_botclasses/ParseMirroredWikiIndexBot.php instead, since it has more robust template parsing) along with a slightly hacked InputBox.hooks.php.
