Laravel 扩展验证自定义消息

发布于05月04日

I wanted to create this extended validation.

Validator::extend('my_custom_validation_rule', function ($attribute, $value, $parameters) {
   // I guess I should be setting the error message for this here.(Its dynamic)
   // We can return true or false here depending upon our need.  
}

I would use this rule like this

'my_field' => 'required|my_custom_validation_rule',

I want to use some dynamic message for the error of "my_custom_validation_rule"

我无法从文档中找到有关它的信息.有什么办法吗？

推荐答案

extend方法允许将消息作为第三个参数传递:

Validator::extend('my_custom_validation_rule', function ($attribute, $value, $parameters) {
    // ...
}, 'my custom validation rule message');

默认情况下，您只能使用动态变量，即:attribute.如果要添加更多内容，请使用Validator::replacer():

Validator::replacer('my_custom_validation_rule', function($message, $attribute, $rule, $parameters){
    return str_replace(':foo', $parameters[0], $message);
});
