如何在phalconphp中的自定義驗證器中運行查詢

Question

我試圖做一個自定義驗證器來檢查電子郵件是否已經提交。 為此，我需要在自定義驗證器中執行查詢，該怎么辦？

use Phalcon\Validation\Validator,

Phalcon\Validation\ValidatorInterface,

Phalcon\Validation\Message;

Class Unique extends Validator implements ValidatorInterface {

    public function validate($validator, $attribute)   {
       // how to execute "SELECT * FROM myTable" here...     
    }

}

Answer 1

如果將myTable映射到模型，則可以：

use Phalcon\Validation\Validator;
use Phalcon\Validation\ValidatorInterface;
use Phalcon\Validation\Message;
use MyTable;

class Unique extends Validator implements ValidatorInterface
{
    public function validate($validator, $attribute)
    {
        $result = MyTable::findFirst("id = 1 AND status = 'sent'");
        ...
    }
}
