Zend RegEx 验证器的自定义有意义的错误消息 [英] Custom meaningful error message for Zend RegEx Validator

问题描述

我正在验证表单中的文本字段，如下所示:

I'm validating a text field in my form as follows:

 $name = new Zend_Form_Element_Text('name');

 $name->setLabel('First Name:')
      ->setRequired(true)
      ->addFilter(new Zend_Filter_StringTrim())
      ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/'))
      ->addErrorMessage('Please enter a valid first name');

我想要完成的是 - 如何显示有意义的错误消息?例如:如果名字是XYZ-"，我怎么能在名字中显示-".

What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.'

有没有办法可以访问正则表达式失败的字符?你会推荐其他的东西吗?

Is there a way I can access what character the regex is failing for? Would you recommend something else altogether?

我想过编写一个自定义验证器，但正则表达式非常简单，所以我不明白这一点.我在任何地方都找不到有关 zend 'regex' 验证器的体面文档.

I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere.

如果我不覆盖默认错误消息，我会简单地得到类似的信息:';;;hhbhbhb' 与模式 '/^[(a-zA-Z0-9)]+$/' 不匹配 - 我显然不想向用户显示.

If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user.

非常感谢您的意见.

推荐答案

如何通俗地告诉用户你的限制是什么?喜欢

How about telling the user in layman's terms what your restrictions are? Like

Error: Only the letters A to Z and numbers are allowed.

(这让我想到了为什么名字可以包含数字的问题...)

(Which leads me to the question why first names can contain numbers...)
