Re: Form in element

The way I would solve it, is probably not a CakePHP thing, but it
would work for me :)

I would make the signup form invoke the same method that the current
page renders from, but with the signup submit button named "doSignup".

In the AppController I would add a method to process the signup and
invoke it from the beforeFilter method (or the form action method) as:

[code]
if ( isset($this->params['form']) and !empty($this->params['form']) )
{
foreach( $this->params['form'] as $action => $actionValue ) {
switch( $action ) {
case 'doSignup" :
... invoke signup processing method ...
...
}
}
}
[/code]

This should ensure that any validation errors are returned together
with the view and your flash message.

Ok, have to admit, the solution is not tested, as my issue was a
little different than yours, but the idea is the same.
Enjoy,
John
