CakePHP验证取决于其他字段

验证规则将如下所示：

var $validate = array(
    'password' => array(            
        'minLength' => array(
            'rule' => array('minLength',6),'message' => 'Your password must be at least 6 characters long.'
        ),'notempty' => array(
            'rule' => 'notEmpty','message' => 'Please fill in the required field.'
        )
    ),'confirm_password' => array(
        'identical' => array(
            'rule' => array('identicalFieldValues','password'),'message' => 'Password confirmation does not match password.'
        )
    )
);

我们的验证函数然后查看传递的字段的数据(confirm_password),并将其与规则中定义的(传递给$compareFiled)的数据进行比较.

function identicalFieldValues(&$data,$compareField) {
    // $data array is passed using the form field name as the key
    // so let's just get the field name to compare
    $value = array_values($data);
    $comparewithvalue = $value[0];
    return ($this->data[$this->name][$compareField] == $comparewithvalue);
}

这是一个简单的例子,但您可以使用$this->数据来执行任何您想要的操作.

您的帖子中的示例可能如下所示：

function requireNotEmpty(&$data,$shouldNotBeEmpty) {
    return !empty($this->data[$this->name][$shouldNotBeEmpty]);
}

规则：

var $validate = array(
  'verify_password' => array(
    'rule' => array('requireNotEmpty','password')
  )
);
