Symfony 1.4验证错误未签名

Question

当我尝试在Symfony 1.4中保存表单时，它给了我这些错误：

Validation failed in class CmsContentElementFile
4 fields had validation errors:

* 1 validator failed on title (unsigned)
* 1 validator failed on alt (unsigned)
* 1 validator failed on link (unsigned)
* 2 validators failed on direction (length, unsigned)

这个错误是什么意思？

编辑：

表单字段中的验证者：

   $this->setValidators(array(
              'title'      => new sfValidatorString(),
              'alt'        => new sfValidatorString(),
              'link'       => new sfValidatorString(),
              'width'      => new sfValidatorInteger(),
              'height'     => new sfValidatorInteger(),
              'direction'  => new sfValidatorPass()
          ));

Answer 1

现在有效。问题在于我给了田地＆＃34;方向＆＃34; param＆＃34; unsigned：1，它也是一个varchar。好吧，解决问题。希望它对某人有所帮助。
