如何在codeigniter中设置私有类以形成验证回调

Suppose this is my controller. (copied from CI documentation)

假设这是我的控制器。（从CI文档复制）

<?php

class Form extends CI_Controller {

    public function index()
    {
        $this->load->helper(array('form', 'url'));

        $this->load->library('form_validation');

        $this->form_validation->set_rules('username', 'Username', 'callback_username_check');
        $this->form_validation->set_rules('password', 'Password', 'required');
        $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
        $this->form_validation->set_rules('email', 'Email', 'required|is_unique[users.email]');

        if ($this->form_validation->run() == FALSE)
        {
            $this->load->view('myform');
        }
        else
        {
            $this->load->view('formsuccess');
        }
    }

    public function username_check($str)
    {
        if ($str == 'test')
        {
            $this->form_validation->set_message('username_check', 'The %s field can not be the word "test"');
            return FALSE;
        }
        else
        {
            return TRUE;
        }
    }

}
?>

But username_check($str) function is public. According to CI documentation if i want to make a private method I need to add "_" like this.

但是username_check（$ str）函数是公共的。根据CI文档，如果我想制作私有方法，我需要像这样添加“_”。

private function _utility()
{
  // some code
}

But how can I set username_check() as private and callback from form validation set_rules?

但是如何将username_check（）设置为私有和来自表单验证set_rules的回调？

Should i use DOUBLE underscore "__" i.e callback__username_check?

我应该使用DOUBLE下划线“__”，即callback__username_check吗？

You can just declare your private function as you have already done:

你可以像你已经完成的那样声明你的私有函数：

function _username_check()
{
  // some code
}

And in the validation rule, use:

在验证规则中，使用：

callback__username_check

As I have seen, this must work just fine!

正如我所见，这必须正常工作！

Remember:

记得：

The _ prefix would take care of your function privacy, so you do not really have to use the keyword private to declare the function to let the form_validation class access to that function!

_前缀会处理你的函数隐私，所以你不必使用关键字private来声明函数让form_validation类访问该函数！
