Zend Db_NoRecordExists - 检查多列

发布于 2024-08-14 23:00:56 字数 512 浏览 4 评论 0原文

Zend Db_NoRecordExists 文档似乎仅限于检查一列。有没有办法在验证条目时检查多个密钥？例如，我允许不同城市使用相同的电子邮件地址。

这是我当前的验证器：

$email->setValidators(array(array('emailAddress'),
                  array('Db_NoRecordExists',false,
                  array(
                    'table'=>'usercities',
                    'field'=>'email',
                  ))));

usercities 表有两列：电子邮件 varchar(64) city_id tinyint

我希望能够检查这些列的组合。这可能吗？我想我必须创建一个自定义验证器。可以在不诉诸自定义类的情况下完成吗？

谢谢！

Zend Db_NoRecordExists docs seem to be limited to checking only one column. Is there a way to check multiple keys when validating an entry? For example, I am allowing the same email address for different cities.

here's my current validator:

$email->setValidators(array(array('emailAddress'),
                  array('Db_NoRecordExists',false,
                  array(
                    'table'=>'usercities',
                    'field'=>'email',
                  ))));

usercities table has two columns:
email varchar(64)
city_id tinyint

I want to be able to check for the combination of these columns. Is this possible? I assume I'll have to create a custom validator. Can it be done without resorting to a custom class?

thanks!
