Ok i got it all working now, unsetting the field did work
here is what i did in my model:
function beforeValidate() {
$u = &$this->data['User'];
$p1 = &$u['password'];
$p2 = &$u['password1'];
if ($p1 != $p2) {
$this->set('error', 'Passwords do not match');
return false;
}
if (empty($p1)) {
unset($this->data['User']['password']);
}
return true;
}
function beforeSave() {
if ($this->validates()) {
if (isset($this->data['User']['password'])) {
$this->data['User']['password'] =
md5($this->data['User']
['password']);
}
return true;
}
return false;
}
controller:
function edit_profile() {
$this->User->id = $this->Session->read('User.id');
if (empty($this->data))
{
$this->data = $this->User->read();
}
else
{
if ($this->User->save($this->data)) {
$this->flash("Your profile has been saved.",
'/users/profile');
}
}
}
