Re: Dynamic Form Data
To make things easier, lets strip this back to the core requirements
then you can add in your specific formatting afterwards
$form-input('User.country_id', array('empty' = '-- Select --'));
echo $ajax-observeField('UserCountryId', array('url' =
'countrySelect', 'update' = 'countryAction'));
This should trigger an ajax call to /app/users/countrySelect which
sets a $regions array and renders /app/view/users/country_select.ctp
using the ajax layout (you've obviously managed to get this far). /
app/view/users/country_select.ctp view could look as simple as
$form-input('User.region_id', array('empty' = '-- Select --'));
echo $ajax-observeField('UserRegionId', array('url' =
'regionSelect', 'update' = 'regionAction'));
I have switched everything back to using cake's conventions, as it's
much easier to learn cake that way.
I imagine both the country and region fields are foreign_keys linking
to tables containing the Countries and Regions which are in turn
related to allow you to know which regions to show for which country
etc. All foreign keys should have _id after them and form-input will
automagically look for a countries array if a field is called
country_id and a regions array for the field region_id.

Re: Dynamic Form Data
I actually ended up creating a .js file to hold my functions and initiated
my Ajax with 'onChange' = someFunction(); I pulled the field value into the
script and passed that into the controller action as a named param. etc.
etc. etc. (the entire process seemed a bit unnecessary and long-winded) The
bottom line is that it worked (for the field that was NOT created
dynamically). I repeated the process for the newly generated form field
which in turn did not work. No matter what I try I just can't retrieve any
data from form fields that get generated dynamically and thus the query
fails.
I'll take another wack at it using the suggestions you made and see how I
make out.
Yes, there are separate tables for country, state, and city. I believe I
have the associations set up correctly but who knows, I've been managing to
make a mess of everything else ;) Region and country are my foreign keys
however they are RegionID and CountryID in the db ... I'll change them to
region_id and country_id. The naming conventions in Cake take a little
getting used to.

Re: Dynamic Form Data
Okay, I managed to get things worked out. It's like anything else I suppose
... it just takes lots of experimenting, trial and error, and a whole lot of
getting used to before that little light comes on and things finally click.
Some things are finally making more sense to me now.
The documentation for Cake is a little vague in areas but that's nothing
new, it seems to be a common theme shared by anything actually worth using.
It gets better with time I suppose.
Thanks for the help. I'm sure I'll have plenty more questions as I try to
get situated with Cake.

Re: Dynamic Form Data
This is probably a mute point as you say your other sites are ajax heavy, but what are you using to view the source. I would suggest something like FireBug as it shows the full source including DOM changes via ajax/javascript. It will also show you the results of your ajax requests. You should of course already be using something similar to FireBug if you have been working with ajax a lot in the past. How have you set up a javascript event for the 1st dynamic field your form creates? My first guess is your adding an observer for the 2nd field before it exists in the dom. You can also add an 'onchange'='jsfunction()' to the options array of form-input to add events to your form fields, this would attach the event to the field as it's created.

Re: Dynamic Form Data
Cake and MVC can be a bit daunting for the first time around especially when having spent years with conventional code, nothing fancy. I re-wrote my Ajax calls and the best I can say is that I didn't have something scripted correctly the first time around because Chrome Java Console and FireBug both now report that the element is indeed empty. For the first field I am (was) using $ajax-observeField for field 1. In the event that field 1 changed, it creates field 2 accordingly and so on down the line with fields 3,4, etc. I can tell you right off the bat that my problem is ignorance. This all feels so alien to me. I initially had it set up with onchange in the options array as you suggested. I'm trying to stick with Cake conventions but my first inclination was go straight for the head of my default.ctp and start with script type= . . . new Ajax.Updater ... etc. Force of habit I suppose. I'm a tad bit thrown off with controllers, actions, views, etc. even though the concept does make sense. Let's say I did want to use onchange ... where would I put the actual function and what syntax should I use? This is the part that is throwing me off.

Re: Dynamic Form Data
Here is one thing I don't quite understand while using $ajax-observeField :
I created a dropdown populated with a list of countries like so ...
echo $html-tableCells(array('bCountry:/b', $form-input('country',
array($countries, 'empty' = '-- Select --', 'label' = '';
$options = array('url' = 'countrySelect','update' = 'countryAction');
echo $ajax-observeField('UserCountry', $options);
When a country is selected it does what I would expect and creates another
input for Region ...
echo $html-tableCells(array('bRegion:/b, $form-input('region',
array($regions, 'label' = '', 'empty' = '-- Select --';
The part I don't understand is that when I echo debug($regions) it displays
an array of regions as I intended however it is not populating the new
dropdown with the array.
If the script is making it far enough to go ahead and create the region
field and the $region array is not empty ... why would it not populate the
dropdown with the array ??
