My way (I'm using it in a subscription form which spreads across 4 pages):
SubscriptionController with four actions: step1(), step2(), step3(),
step4() (name them as you want).
Data is shared across the four steps within the Session data. Think
about the first step for a subscription, selecting the subscription
model (1 month, 12 months and so on). In the step1() method I save the
data to the session together with the information that step 1 was
completed (step 2 will redirect to step 1 if step 1 wasn't completed).
public function step1()
{
(...)
if ($this->data['Subscription']['subscription_type'] == 'yearly')
{
$this->Session->write('Subscription.step1_done', true);
$this->Session->write('Subscription.subscription_type', '12months');
}
$this->redirect(array('controller' => 'subscription', 'action' =>
'step2'));
}
Same logic applies to step2(), step3() and step4(). Saving data to
database is done in step4 when all required steps are done.
