出于某种原因，我的分层模型 - 视图 - 控制器中的CodeIgniter回调不起作用，但我确实有MY_form_validation库函数。
如果需要或丢失，它应该抛出$ error。
我重命名了我的图片文件夹，但没有出现任何错误。任何想法如何使我的回调验证工作？这是我的代码：
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

答案 0 :(得分：0)
$this->form_validation->set_rules('input_name_attribute', 'The Name', 'rules|seperated|like|this);

来自用户指南：
$this->form_validation->set_rules();
上述函数将三个参数作为输入：
字段名称 - 您给出表单字段的确切名称。
A＆＃34;人类＆＃34;此字段的名称，将插入错误消息中。例如，如果您的字段命名为＆＃34; user＆＃34;你可以给它一个人名＃34;用户名＆＃34;。注意：如果您希望将字段名称存储在语言文件中，请参阅翻译字段名称。
此表单字段的验证规则。
修改
你应该这样做;
public function index()
{
if ( $this->validate() )
{
echo 'validation passed';
}
else
{
echo 'validation failed!';
}
}
您的验证功能正在检查您是否启用了php扩展并加载了库，因此无需使用form_validation。表单验证仅适用于表单提交。
