我得到错误
**致命错误:调用未定义的方法CI_Form_validation::set_fields() **
我知道这个错误是因为验证库贬值并被Form_Validation
取代在当前库中是否有不需要更改太多代码的替代品?
没有快速/简单的方法来迁移此代码(您的表单字段配置)到较新的版本，它必须手动完成。如果你的旧配置是这样的:
$fields['password'] = "Password";
你需要把它改成:
$fields[] = array(
'field' => 'password',
'label' => 'Password'
);
使用set_rules():
$this->form_validation->set_rules($fields);
这是对您的Codeigniter安装的主要升级(发布日期:2007年7月12日…V1.5现在已经相当老了)，所以没有必要瞎折腾，试图半升级你的代码，只要咬紧牙关，确保测试。
胡说，老兄，这是我能想出的最好的办法了
$this->form_validation // automatically assign's {key}{value} pairs via $_POST
