CakePHP验证规则：带空格的字母数字 [英] CakePHP validation rule: alphanumeric with spaces

问题描述

我的数据库中有一个描述字段，该字段接受字母数字字符和空格以及换行符。我想在我的 Server 模型中设置该验证规则。

这是我现在拥有的：

 <？php 
 
类服务器扩展AppModel {
 
 public $ validate = array （
 // ... 
'描述'=>数组（
'字符'=>数组（
'规则'=>'alphaNumeric'，
'message'=>'仅字母数字字符'
）
），
 // ... 
）; 
 
} 
  

如何修改此值以允许空格和换行以及字母数字字符？我以为Cake会为此建立验证规则，但我看不到。我需要自己编写并使用一些正则表达式吗？

谢谢。

解决方案

alphaNumeric表示不带空格的字母数字字符。因此，您必须使用自己的正则表达式模式。

示例：

 说明 => array（
'characters'=> array（
'rule'=> array（'custom'，'/ ^ [a-z0-9] * $ / i'），
'message'=>'仅带空格的字母数字字符'
）
），
  

I have a description field in my database which accepts alphanumeric characters and spaces, as well as new line characters. I want to set that validation rule in my Server model.

Here's what I have now:

<?php

class Server extends AppModel {

    public $validate = array(
        // ...
        'description' => array(
            'characters' => array(
                'rule'     => 'alphaNumeric',
                'message'  => 'Alphanumeric characters only'
            )
        ),
        // ...
    );

}

How can I modify this to allow spaces and new lines as well as alphanumeric characters? I thought Cake would have a build in validation rule for this but I can't see one. Do I need to write my own and use some regex?

Thanks.

解决方案

alphaNumeric in CakePHP means alphanumeric characters without spaces. Therefore you have to use your own regex pattern.

Example:

'description' => array(
    'characters' => array(
        'rule' => array('custom', '/^[a-z0-9 ]*$/i'),
        'message'  => 'Alphanumeric characters with spaces only'
    )
),
