Thanks a lot.

I have improve performance of my CakePHP Intranet, instead of loading from MySQL DB all the 8000 cities, my user select only one hundred zones runtime, and then, by the handler request, software loads only the interesting cities. It was very important because all my system work under a SaaS logic. A good service.

thank you very much for this tutorial. You saved my time a lot.

By the way, it would be better when all the variables could be explained in more details.

It should be in the $this->data array. If it’s not it would be in the standard $_POST array.

Hi Jamie

How do I retrieve the selected value of the select box in my controller?

My update_select function does a find() to retrieve a list of items and then in my view I simply output them as follows: echo “– Select –\n”; foreach($items as $k => $v) { echo “$v\n”; } ?>

I’m not sure if this is the best approach for the view as I wrote this quite a while ago.

I suppose the “better” approach would be to return JSON and have Javascript code that parses the JSON and creates option elements, but my example above seemed to work in the various browsers I tested.

I’ve got the Ajax call pulling up the “update_select” view content, with some static placeholder data. However, it’s not showing the iterated array data for the options. I’ve either messed up the calls in my update_select() function, or the Ajax call isn’t invoking the function at all.

Would it be possible for you to post an example of your update_select() function; which pulls the constrained list of articles and sends it to the update_select view? Any help with this would be greatly appreciated. Thanks in advance!

Hey ajmacaro, no problem. It should be setup as follows:

in app/controllers/users_controller.php you should have two functions add() and update_select().

you should then create two views in app/views/users, add.ctp and update_select.ctp. Add.ctp should contain the first snippet to create the two select boxes and then update_select.ctp should contain the second snippet, that loops through the carriers and writes out the select box options.

hopefully that’s more clear.

well, this is pretty nice. but really, can you provide a complete and working example on this?

in what should “update_select.ctp” located?
