单独生成一个 form_validation.php 文件，放到【applicationconfig】文件夹下：
内容为：
<?php
/*
* 配置验证规则
*/
$config = array(
'zhuce' => array(
array(
'field' => 'username',
'label' => '用户名',
'rules' => 'trim|required|min_length[2]|max_length[12]|callback_username_check' //|xss_clean'
), //将用户名通过“xss_clean”函数处理去掉了有害数据。
array(
'field' => 'password',
'label' => '密码',
'rules' => 'trim|required|md5'
),
array(
'field' => 'passconf',
'label' => '再次输入',
'rules' => 'trim|required|md5|matches[password]'
),
array(
'field' => 'email',
'label' => '邮箱',
'rules' => 'trim|required|valid_email'
)
),
'login' => array(
array(
'field' => 'username',
'label' => '用户名',
'rules' => 'trim|required|min_length[2]|max_length[12]' //|xss_clean'
), //将用户名通过“xss_clean”函数处理去掉了有害数据。
array(
'field' => 'password',
'label' => '密码',
'rules' => 'trim|required|md5'
)
)
);
调用时：
$this->load->library('form_validation');
$bool = $this->form_validation->run('login');
if ($bool == FALSE) {
// 返回到注册页面
}else{
//验证没有问题
}
