symfony 表单验证在使用正则表达式验证之前使用正则表达式清理

发布于 2024-09-24 06:52:43 字数 568 浏览 5 评论 0原文

我正在使用 Symfony 1.4，并且在表单验证方面有点困难。我有一个如下所示的验证器：

$this->setValidator('mobile_number', new sfValidatorAnd(array(
    new sfValidatorString(array('max_length' => 13)),
    new sfValidatorRegex(array('pattern' => '/^07\d{9}$/'),
    array('invalid' => 'Invalid mobile number.')),
  )
));

这是一个用于匹配英国手机号码的简单正则表达式。

然而我的问题是，如果有人提交了这样的字符串：“07 90 44 65 48 1”，正则表达式将失败，但如果首先清理字符串以删除空格，他们会给出有效的数字。

我的问题是我不知道在 symfony 表单框架中的哪个位置可以完成此任务。

我需要从用户输入中删除除数字之外的所有内容，然后使用我的 mobile_number 验证器。

任何想法将不胜感激。谢谢。

I'm using Symfony 1.4 and am a little stuck regarding form validation. I have a validator like the one below:

$this->setValidator('mobile_number', new sfValidatorAnd(array(
    new sfValidatorString(array('max_length' => 13)),
    new sfValidatorRegex(array('pattern' => '/^07\d{9}$/'),
    array('invalid' => 'Invalid mobile number.')),
  )
));

That is a simple regex for matching a UK mobile phone number.

However my problem is that if someone submitted a string like this: "07 90 44 65 48 1" the regex would fail but they have given a valid number if a the string was cleaned to remove whitespace first.

My problem is that I don't know where within the symfony form framework I would accomplish this.

I need to strip everything but numbers from the user input and then use my mobile_number validator.

Any ideas would be greatly appreciated. Thanks.

您可以使用标准验证器的组合来完成此操作，但构建您自己的自定义验证器可能是最简单的。 symfony 网站上有一个指南： http://www.symfony-project.org/more-with-symfony/1_4/en/05-Custom-Widgets-and-Validators#chapter_05_building_a_simple_widget_and_validator

我认为它应该看起来像这样的内容：

class sfValidatorMobilePhone extends sfValidatorBase
{
    protected function doClean($value)
    {
        $value = preg_replace('/\s/','',$value);

        if (
            (0 !== strpos($value, '07')) ||
            (13 < strlen($value)) ||
            (0 !== preg_match('/[^\d]/', $value))
           )
        {
            throw new sfValidatorError($this, 'invalid', array('value' => $value));
        }
        else
        {
            return $value;
        }
    }
}

将其保存为 lib/validator/sfValidatorMobilePhone.class.php。然后你可以将其称为

$this->setValidator('mobile_number', new sfValidatorMobilePhone());

You may be able to do this with a combination of standard validators, but it might well be easiest to construct your own custom validator. There is a guide to this on the symfony website: http://www.symfony-project.org/more-with-symfony/1_4/en/05-Custom-Widgets-and-Validators#chapter_05_building_a_simple_widget_and_validator

I think it should probably look something like this:

class sfValidatorMobilePhone extends sfValidatorBase
{
    protected function doClean($value)
    {
        $value = preg_replace('/\s/','',$value);

        if (
            (0 !== strpos($value, '07')) ||
            (13 < strlen($value)) ||
            (0 !== preg_match('/[^\d]/', $value))
           )
        {
            throw new sfValidatorError($this, 'invalid', array('value' => $value));
        }
        else
        {
            return $value;
        }
    }
}

Save this as lib/validator/sfValidatorMobilePhone.class.php. You could then call it as

$this->setValidator('mobile_number', new sfValidatorMobilePhone());

我不了解 Symfony，所以我不知道你会如何清理输入。如果您可以以某种方式进行基于正则表达式的搜索和替换，则可以搜索 /\D+/ 并将其替换为任何内容 - 这将从字符串中删除除数字之外的所有内容。小心，它还会删除可能相关的前导 + （？）。

如果您无法在验证之前执行“清理步骤”，您可以尝试像这样验证它：

/^\D*07(?:\d*\d){9}\D*$/

这将匹配包含恰好 11 个数字（以及任意多个非数字字符）的任何字符串，其中前两个需要是07。

I don't know Symfony, so I don't know how you would go about cleaning the input. If you can do a regex-based search-and-replace somehow, you can search for /\D+/ and replace that with nothing - this will remove everything except digits from your string. Careful, it would also remove a leading + which might be relevant (?).

If you can't do a "cleaning step" before the validation, you could try validating it like this:
