Start by forcing the $id parameter to the edit action, then pass on the
selected ID to the view. Then on the view set the action of the form to
include this id.
So on the controller set the data regardless if you got submitted
information or not, like so:
function edit ($id)
{
$this->User->id = $id;
$record = $this->User->read();
if (!empty($this->data))
{
if ($this->User->save($this->data['User'], true,
array('email',
'date_expires'))) {
$this->redirect('/users/index');
}
}
else
{
$this->data = $record;
}
$this->set('record', $record);
}
Finally on the view when you need to print stuff from readonly values, use
$record, like so:
<h2>User <?php echo $record['User']['username']; ?></h2>
And don't forget to set the form action properly:
<?php echo $form->create('User', array('action'=>'/users/edit/' .
$record['User']['id'])); ?>
This last form code is for 1.2, for 1.1 do:
<?php echo $html->formTag('/users/edit/' . $record['User']['id']); ?>

So be smart, be cool, and share your knowledge.
BAKE ON!

Asunto: Problem with Controller: How to mix db and posted values on edit?
I want the users of my application to be able to change only certain
aspects of their profile. Limiting the fields in the save method
prevents users from modifying fields like registration date or
username. My problem is: If there are validation errors these "read-
only" properties of the model disappear.
