Wolfgang Drews (of DynamicWebPages) has posted a mini-tutorial on his personal blog showing how to integrate the popular Zend Framework with the YUI Javascript libraries from Yahoo! to create an autocomplete field in your app.
Maybe this short snippet helps someone out there when using YUI autocomplete feature together with the Zend Framework or any other Framework, that creates URLs like http://domain.tld/controller/action/param/value.
He modifies the Yahoo library to change a few of the defaults to make it more Zend Framework-friendly: changing the default query format and updating the "append parameters" concatenation to replace the ampersand with a slash.
