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.
