Yea, probably much easier for me to explain what I've done and what I'd like to do.
So basically I implemented the ajax select box using the code below: http://www.devmoz.com/blog/2007/04/04/cakephp-update-a-select-box-using-ajax/ My code set up is more less the same as the example posted in that article. The ajax select box I created allows a user to select a car make, then year, then model. Currently, I have this working in index.ctp just like the example, and the ajax calls the update_select.ctp. What I would like to do, is move this ajax selector into my navigation bar so that the user can change is car at any point during his browsing experience. This means that no matter what view he's on, he can still use my ajax selector through the navbar. The complication is that my code is in my car_controller "index.ctp" and uses "update_select.ctp" with observefield (like the example). I want to somehow move this code/functionality into my default.ctp. Perhaps you guys can suggest the best strategy? Even if I move the code from index.ctp to default and access the set variable from the app_controller before filter (as suggested), I still have the issue of ajax having to call the update_select function which I have no idea where I would move it to (perhaps in the app_controller?)... I apologize for the constant questions and greatly appreciate the help you guys have been giving me :) And then we scroll back 15 emails : If this works, then I would suggest to add your layout data to the view inside the beforeFilter() method of AppController and then use this data in your layout. Might even consider creating an element for the part that uses this data ... > > :) > > On Sat, Oct 3, 2009 at 10:34 AM, Miles J <mileswjohn...@gmail.com> wrote: > >> >> Do it in the beforeFilter() of your AppController, that will apply it >> to all views and layouts. >> >> On Oct 3, 1:18 am, hahmadi82 <hahmad...@gmail.com> wrote: >> > Now I see!
