Question

我正在尝试为Ip-Address创建验证规则，以下代码无效：

$validator
        ->add('ipfirst', 'validIp', ['rule' => 'ip', 'message' => 'Ip is not valid!'])
        ->requirePresence('ipfirst', 'create')
        ->notEmpty('ipfirst');

如果有人能直接指出我，那就太棒了，谢谢！

Answer 1

Cake 3.x中已有IPv4和IPv6验证方法： - ）

http://api.cakephp.org/3.3/class-Cake.Validation.Validator.html#_ipv4＆amp; http://api.cakephp.org/3.3/class-Cake.Validation.Validator.html#_ipv6

像这样使用它：

$validator
    ->ipv4('ipfirst', 'Please enter ip address')
    ->requirePresence('ipfirst', 'create')
    ->notEmpty('ipfirst');

当然，如果你想要的话，改为ipv6：P

You can add custom validation rule with regular expression like:
// you can change regular expression according to you requirement.
$validator
    ->notEmpty('ipfirst', 'Please enter ip address')
    ->add('ipfirst','validIp',[
        'rule'=>  function($value){
            if (preg_match('/^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/', $value)) {
                    return true;
            }
            return false;
        },
        'message'=>'Please enter a valid ip address.',
    ]);
