Re: Ajax in Cake -> Javascript Response

[mason k]

You'll probably get more helpful responses if you explain what you're
trying to do in English, rather than in code, particularly a code, the
understanding of which, is predicated on the knowledge of a syntax and
methodology which is not part of the Cake universe.

Also: Cake 1.1 or 1.2?   Though the CakePHP documentation is not on
the same level as Rails documentation, there is a manual which
explains quite a lot.  The manual is at http://manual.cakephp.org for
Cake 1.1, and http://tempdocs.cakephp.org/#TOC12047 for Cake 1.2.

Here's the gist of Ajax in Cake.

1.  Ajax updating of web pages is handled by the integration of the
Prototype.js and Scriptaculous.js libraries.
2. Integration of the libraries if achieved by use of the AjaxHelper,
and the inclusion of the RequestHandler component.  Read the manual to
learn how to include Helpers and Components in your code.
3. I don't know Rails, but I know ruby, so I am taking a stab at your
question in particular.
a. It sounds like the method you want is AjaxHelper::Link (make sure
to  the js files in your layout or view).
b. (Learn bout AjaxHelper at http://api.cakephp.org/1.2/class_ajax_helper.html
<- This is the API.  You have to learn to love it.)
c. You call this method in the view with $ajax->link.

Hope this helps

Re: cakephp 1.2 form

[mason k]

Thanks for the answer, but I'd love a little more guidance myself.
Can you answer OP's Q1, which is the difference between $ajax->form
and $ajax->submit?

Also, please explain the $this->render('view','ajax'); line of code?
There is nothing in the API (http://api.cakephp.org/1.2/
class_controller.html#90046e6b62c91452a987c9573372c2ac) about a
special 'ajax' value as a layout option.  What does this do?  Does it
render no layout if the request was ajax?  How does the action know
whether an incoming request is coming from an Ajax source or not?
