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.

Answer 1

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];
    }
