我在application/config/validation_rules.php中设置了验证规则,如下所示(短版(
$config = array(
'member/register' => array(
'field' => 'language',
'label' => 'language',
'rules' => 'required|min_length[5]|max_length[12]'
),
array(
'field' => 'email',
'label' => 'email',
'rules' => 'required|valid_email'
),
array(
'field' => 'password',
'label' => 'password',
'rules' => 'required|min_length[8]'
),
array(
'field' => 'verify_password',
'label' => 'password',
'rules' => 'required|min_length[8]|matches[password]'
));
我这样称呼它:
$this->config->load('validation_rules');
$this->form_validation->set_rules($config);
if($this->form_validation->run('member/register') == FALSE)
{
$page = array(
'meta_title' => 'member registration',
'load_page' => 'front/register_view'
);
$this->load->view('front/template', $page);
}
validation_errors((函数不仅没有显示任何内容,而且我还得到了这个错误:
Message: Undefined variable: config
更新:(这是我的控制器(
class register extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->library('form_validation');
}
function index()
{
$this->config->load('validation_rules', TRUE);
$this->form_validation->set_rules($this->config->item('config', 'validation_rules'));
if($this->form_validation->run('member/register') == FALSE)
{
//validation doesnt pass, load view
$page = array(
'meta_title' => 'member registration',
'load_page' => 'front/register_view'
);
$this->load->view('front/template', $page);
}
else
{
$register_data = array(
'language' => $this->input->post('language'),
'email' => $this->input->post('email'),
'password' => md5($this->input->post('password')),
'fname' => $this->input->post('fname'),
'lname' => $this->input->post('lname'),
'phone' => $this->input->post('phone'),
'address' => $this->input->post('address'),
'address2' => $this->input->post('address2'),
'city' => $this->input->post('city'),
'state' => $this->input->post('state'),
'zipcode' => $this->input->post('zipcode'),
'gfname' => $this->input->post('gfname'),
'glname' => $this->input->post('glname'),
'gphone' => $this->input->post('gphone')
);
$this->session->set_userdata($register_data);
}
}
function package()
{
$page = array(
'meta_title' => 'Register Package',
'load_page' => 'register_package_view'
);
$this->load->view('includes/template', $page);
}
}
我遇到了同样的问题,但我通过使用以下配置解决了它:
在我的应用程序/config/form_validation.php中:
$config = array(
"register" => array(
array(
"field" => "username",
"label" => "Username",
"rules" => "required"
)
)
);
在application/config/autoload.php中自动加载自定义配置文件"form_validation.php":
$autoload['config'] = array('form_validation');
在我的控制器中:
// manually set rules by taking $config["register"] from form_validation.php
$this->form_validation->set_rules($this->config->item("register"));
// call run() without parameter
if ($this->form_validation->run() == FALSE) {
$this->load->view("user/register_test");
} else {
echo "Form content is correct";
}
我尝试过使用$this->form_validation->run("register")
调用验证器,但没有使用$this->form_validation->set_rules()
函数,但我没有成功。通过从form_validation.php中的配置数组中检索规则来手动设置规则,让我的日子过得很愉快。
如果要扩展form_validation库,则需要将$config
数组传递给父构造函数:
class MY_Form_validation extends CI_Form_validation {
/**
* constuctoooor
*/
function MY_Form_validation($config){
parent::__construct($config);
}

使用文档中概述的方法也更清洁:http://ellislab.com/codeigniter%20/user-guide/librarys/form_validation.html#保存配置以避免调用$this->form_validation->set_rules(...);
/**
* This is the POST target for the password reset form above
* @return null
*/
public function submit(){
// perform validation //
if($this->form_validation->run() == FALSE){
// display error on sign-up page //
$this->session->set_flashdata("system_validation_errors", validation_errors());
redirect('member/forgot/password');
}
// more awesome code
}
$this->config->load('validation_rules');
$this->form_validation->set_rules($config);
应该是:
$this->config->load('validation_rules', TRUE);
$this->form_validation->set_rules($this->config->item('validation_rules', 'validation_rules'));
根据文件:
// Loads a config file named blog_settings.php and assigns it to an index named "blog_settings"
$this->config->load('blog_settings', TRUE);
// Retrieve a config item named site_name contained within the blog_settings array
$site_name = $this->config->item('site_name', 'blog_settings');
您的规则是错误的,您忘记将验证组放入数组中:
$config['validation_rules'] = array(
'member/register' => array(
array(
'field' => 'language',
'label' => 'language',
'rules' => 'required|min_length[5]|max_length[12]'
),
array(
'field' => 'email',
'label' => 'email',
'rules' => 'required|valid_email'
),
array(
'field' => 'password',
'label' => 'password',
'rules' => 'required|min_length[8]'
),
array(
'field' => 'verify_password',
'label' => 'password',
'rules' => 'required|min_length[8]|matches[password]'
)
)
);
