我有这些问题,我想在“文本”类型的三种输入形式上设置规则,我的规则是至少这三种中的一种具有值(三,),我不知道如何在CI中设置它们,因为它们在run()被触发时完全执行,你们中的任何人都知道如何设置这些规则以在CI中形成验证请做分享你的知识。

您可以设置自己的验证功能类型。它有很好的记录here,但摘录如下:
<?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;
}
}
}
?>
callback_username_check
正在调用控制器中的username_check
函数

// $data is $_POST
function my_form_validator($data)
{
$data = 'dont worry about this';
// you have access to $_POST here
$field1 = $_POST['field1'];
if($field1 OR $field2 OR $field3)
{
// your fields have value
return TRUE;
}
else
{
// your fields dont have any value
$this->form_validation->set_message('field1', 'At least one of the 3 fields should have a value');
return FALSE;
}
}
