CodeIgniter：自定义验证规则不能在帮助程序中？ [英] CodeIgniter: custom validation rules can't be in a helper?

问题描述

我创建了一个验证助手，它应该具有我的所有自定义验证规则。问题是，当我在表单验证中使用它们时，它们似乎被忽略。如果我移动在执行表单验证的控制器中的函数，一切都像一个魅力。我的验证助手是自动加载的。

有没有什么理由为什么我不能使用这些验证功能，如果我把它们放在帮手？感谢。

解决方案

帮助器和控制器中的函数显然不同。

创建扩展 MY_Form_validation.php 在 libraries / 中添加函数，最后设置规则而不 callback _

 <？php if（！defined（'BASEPATH'））exit（'不允许直接脚本访问）; 
 
 class MY_Form_validation extends CI_Form_validation {
 
 / * set_rule（'custom_require'）* / 
 function custom_require（$ str）{
 
 return（bool）$ str; 
 
} 
 
} 
  




I've created a "validation helper" that was supposed to have all my custom validation rules. The problem is that when I use them in my form validation, they seem to be ignored. If I move the functions in the controller that is doing the form validation, everything works like a charm. My validation helper is autoloaded.

Is there any reason why I can't seem to use these validation functions if I put them in a helper? Thanks.

解决方案

A function in a helper and a controller are different obviously.

Create an extended MY_Form_validation.php in your libraries/, add the functions there and finally set the rules without callback_ and just their function name.

Example:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Form_validation extends CI_Form_validation {

    /* set_rule('custom_require') */
    function custom_require($str) {

        return (bool)$str;

    }

}
