Laravel自定义验证消息 [英] Laravel custom validation messages

问题描述

我正在尝试使用Laravel验证英国邮政编码.这就是我所拥有的:

I'm trying to validate a UK postcode using Laravel. Here's what I've got:

//routes.php
    $rules =  array(
        'pcode' => array('required:|Regex:/^([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([A-Za-z][‌​0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z])))) [0-9][A-Za-z]{2})$/') 
    );

    $messages = array(
        'required' => 'The :attribute field is required.',
        'pcode' => array('regex', 'Poscode should be a valid UK based entry'),
    );

    $validator = Validator::make(Input::all(), $rules, $messages);

在我的blade中:

<input id="postcode" name="pcode" value="{{Input::old('pcode')}}" type="text" placeholder="Postcode" class="form-control" xequired="" />
    @if( $errors->has('pcode') ) <span class="error" style='background-color: pink;'>{{ $errors->first('pcode') }}</span> @endif

如果我提交的表单中的pcode字段为空，则会警告我输入必填字段.如果我输入了无效的邮政编码"74rht"，则我的验证器没有执行任何操作或无法显示上述自定义消息?

If I submit the form with an empty pcode field, it warns me for a required field. If I enter an invalid postcode, '74rht' say, my validator does nothing or fails to display my custom message as defined above?

推荐答案

Laravel 手册状态:

The Laravel manual states:

Note: When using the regex pattern, it may be necessary to specify rules in an array instead of using pipe delimiters, especially if the regular expression contains a pipe character.

将$rules更改为以下结构:

$rules = array(
    'pcode' => array(
        'required',
        'Regex:/^([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([A-Za-z][‌​0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z])))) [0-9][A-Za-z]{2})$/'
    ) 
);

如果这不起作用，则可能是您的正则表达式无效，请尝试使用更简单的正则表达式来检查验证程序是否有效.

If that doesn't work, then maybe your regex isn't valid, try to use a easier regex to check if the validator works.
