cakephp密码验证

您使用的是authcomponent吗?请注意,它会散列所有输入的密码字段(但不是“密码确认”字段,请检查 debug($this->data) ,因此字段永远不会相同。 Read the manual and use AuthComponent::password 去检查一下。

public $validate = array(
    'password' => array(
        'confirm' => array(
            'rule' => array('password', 'password_control', 'confirm'),
            'message' => 'Repeat password',
            'last' => true
        ),
        'length' => array(
            'rule' => array('password', 'password_control', 'length'),
            'message' => 'At least 6 characters'
        )
    ),
    'password_control' => array(
        'notempty' => array(
            'rule' => array('notEmpty'),
            'allowEmpty' => false,
            'message' => 'Repeat password'
        )
    )
);

public function password($data, $controlField, $test) {
    if (!isset($this->data[$this->alias][$controlField])) {
        trigger_error('Password control field not set.');
        return false;
    }

    $field = key($data);
    $password = current($data);
    $controlPassword = $this->data[$this->alias][$controlField];

    switch ($test) {
        case 'confirm' :
            if ($password !== Security::hash($controlPassword, null, true)) {
                $this->invalidate($controlField, 'Repeat password');
                return false;
            }
            return true;

        case 'length' :
            return strlen($controlPassword) >= 6;

        default :
            trigger_error("Unknown password test '$test'.");
