回调功能，用于在配置文件中进行表单验证 [英] Callback function for form validation in config file

问题描述

我正在尝试进行电子邮件验证，由此电子邮件的域将为 @ abc123.com 。我已经将表单验证规则分离到 application / config 文件夹中的另一个文件中，该文件名为 form_validation.php 。我的规则之一包括 callback_email_check 。

I'm trying to do an email validation whereby the domain of the email would be @abc123.com. I've separated my form validation rules into another file in the application/config folder called form_validation.php. One of my rules consists of a callback_email_check.

该函数应该放在哪里？在主控制器中还是与 form_validation.php 文件一起，所有我的表单验证规则都在哪里？我尝试同时使用这两个选项，但是在显示错误消息的地方，我得到的输出是无法访问与您的字段名称电子邮件对应的错误消息。（email_check）。

Where should I put the function? In the main controller or together with the form_validation.php file where all my form validation rules are? I've tried putting at both options but at where I display my error message I'm getting an output saying Unable to access an error message corresponding to your field name Email.(email_check).

function email_check($email)
{
    if( strpos($email, '@abc123.com') !== FALSE ) return TRUE;

    $this->form_validation->set_message('email', 'Please use abc123 email only.');

    return FALSE;
}

form_validation.php

form_validation.php

推荐答案

在您的函数email_check中，set_message不正确

On your function email_check, the set_message is not correct it should be the same name as the function.

更改此

$this->form_validation->set_message('email', 'Please use abc123 email only.');

至

$this->form_validation->set_message('email_check', 'Please use abc123 email only.');
