Password Confirm Validation CakePHP

Question

I have searched far and wide, tried every trick in the book, but I still can't get my CakePHP application to perform simple Password Confirm validation. I've tried creating a custom validation rule like this:

'passwordequal' => array('rule' => 'checkpasswords' , 'message' => 'Passwords Do Not Match')

Then defined 'checkpasswords' like this:

public function checkpasswords(){

    if(strcmp($this->data['User']['new_password'],$this->data['User']['confirm_password']) == 0 )
    {
        return true;
    }
    return false;
}

'new_password' and 'confirm_password' are the password input fields. This didn't work. Then I tried one in which I hashed the 'confirm_password'. That didn't work either. I have other 'rules' as well that are not being validated, like 'notempty', which I believe is one of the standard CakePHP rules. Can anybody please help. I know this question has been asked a few times but none of those solutions have worked for me. CakePHP documentation hasn't helped much either.

Did you output those values to see if they are being read by your method correctly before the comparison? — Hanky Panky
can you show us an example of the $this->data input that's failing? you should show your whole model class code too. — Derek
You can find tips, code examples as well as a full working behavior for that here: dereuromark.de/2011/08/25/working-with-passwords-in-cakephp — mark
@mark Your Password Behavior has helped me a lot. Everything is working perfectly now. Thank you. — kingLoosh

two fields in view file

echo $this->Form->input('password');
echo $this->Form->input('repass');

Model file

<?php
class Post extends AppModel {
    public $validate = array(
        'repass' => array(
            'equaltofield' => array(
            'rule' => array('equaltofield','password'),
            'message' => 'Require the same value to password.',
            //'allowEmpty' => false,
            //'required' => false,
            //'last' => false, // Stop validation after this rule
            'on' => 'create', // Limit validation to 'create' or 'update' operations
            )
        )
    );

function equaltofield($check,$otherfield)
    {
        //get name of field
        $fname = '';
        foreach ($check as $key => $value){
            $fname = $key;
            break;
        }
        return $this->data[$this->name][$otherfield] === $this->data[$this->name][$fname];
    } 
}?>
