I did a bit of playing around with Ajax in Cake and was able to extract
field values using Prototype (it's just as easy to use JQuery or Mootools
with Cake 1.3).
Instead of using $ajax->observeField I used onChange="" in my combo passing
in the id of element I wanted to update and the action I wanted to use for
the url. I was using it to "pre-validate" passwords and although I no longer
use it it did exactly what I wanted.
Here is an example:
*view:*
$form->input('confirm_password', array( 'type' => 'password', 'onChange'
=>'checkPass(\'passOkay\', \'confirmPassword/id1:\');' ));
*.js** *
function checkPass(id, url)
{
var pw1 = Form.Element.getValue('UserPassword');
var pw2 = Form.Element.getValue('UserConfirmPassword');
var ext = '/id2:'+pw2;
new Ajax.Updater(id,url +pw1+ext,{asynchronous:true});
}
*controller:*
function confirmPassword()
{
$pw1 = $this->params['named']['id1'];
$pw2 = $this->params['named']['id2'];
$pwarray = array($pw1, $pw2);
$this->set('pwmatch', $pwarray);
}
>From there I was able to access my form values in confirm_password.ctp via
$pwmatch array. I was simply displaying messages based on the contents of
the array but you could do whatever you like with the data inside the
controller before passing it along.
I'm new to Cake and that was my first attempt at extracting values from a
form but it worked just fine.
