cakephp form validation password comparision - forms

Question

I have a function to reset a password.
At the point where I have to compare the password and the password_confirm field, I get a strange behavior:
My form
echo $this->Form->hidden('tkn', array('value' => $tkn));
echo $this->Form->hidden('uid', array('value' => $uid));
echo $this->Form->input('password',array('type' => 'password', 'name' => 'data[Appuser][password]'));
echo $this->Form->input('password_confirm',array('type' => 'password', 'name' => 'data[Appuser][password_confirm]'));
My model validation:
var $validate = array(
'password' => array(
'rule' => array('minLength', '6'),
'message' => '{password} minLength 6!'
),
'password_confirm' => array(
'rule' => array('equaltofield','password'),
'message' => '{password_confirm} not equal!'
),
);
function equaltofield($val1, $val2){
return $this->data[$this->alias][key($val1)] == $this->data[$this->alias][$val2];
}
My Controller:
if($this->Appuser->save($this->data)){
$this->Session->setFlash(__('Password has been updated'));
}else{
debug($this->Appuser->invalidFields());
}
Now:
When I submit an empty form I get the following returned from the invalidFields()
array(
'password' => '*****',
'password_confirm' => array(
(int) 0 => '{password_confirm} not equal!',
(int) 1 => '{password_confirm} not equal!'
)
)
Question 1: Why do I not get the message, that the password has not its minlength?
Question 2: Why do I get the second message twice for comparing the password?
When typing in 2 different password with min length, I get this again:
array(
'password_confirm' => array(
(int) 0 => '{password_confirm} not equal!',
(int) 1 => '{password_confirm} not equal!'
)
)
When debug($this->data) I also get this (if that helps somehow)
array(
'Api' => array(
'tkn' => '6837d241bf1076c3c55a95abbcfafa04dc19a33c',
'uid' => '1'
),
'Appuser' => array(
'password' => '*****',
'password_confirm' => 'asdfgh'
)
)
Any ideas regarding my two questions above?
Thanks in advance!!

Answer 1

Try this
var $validate = array(
'password' => array(
'rule' => array('minLength', '6'),
'message' => '{password} minLength 6!'
),
'password_confirm' => array(
'rule' => 'equaltofield',
'message' => '{password_confirm} not equal!'
),
);
function equaltofield($data){
return $this->data[$this->alias]['password'] == $this->data[$this->alias]['password_confirm'];
}
