That should work. The helper just uses whatever the controller's $data
array is set to.
If it's an edit form, make sure you're not resetting again by a find()
call before the method is done (and the form is reloaded).
function edit($id)
{
if (!empty($this->data))
{
if (validates and save)
{
do redirect
}
}
else if empty($this->data))
{
read the data into $this->data
}
// if validation/save failed, you'll pass through here again
// before reloading the form. Thus, the above else block is
// necessary to avoid resetting $data
}
