我的 View 中出现此错误，但我找不到问题出在哪里
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: errors
Filename: views/register_user.php
Line Number: 5
查看:
<?php if($errors){ ?>
<div style="background:red,color:white;">
<?=$errors?>
</div>
<? } ?>
这里是 Controller
function register(){
if($_POST){
$config=array(
array(
'field'=>'username',
'label'=>'Username',
'rules'=>'trim|required|min_length[3]|is_unique[users.username]'
),
array(
'field'=>'password',
'label'=>'Password',
'rules'=>'trim|required|min_length[5]|max_length[15]'
),
array(
'field'=>'password2',
'label'=>'Password Confirmed',
'rules'=>'trim|required|min_length[5]|matches[password]'
),
array(
'field'=>'user_type',
'label'=>'User Type',
'rules'=>'required'
),
array(
'field'=>'email',
'label'=>'Email',
'rules'=>'trim|required|is_unique[users.email]|valid_email'
)
);
$this->load->library('form_validation');
$this->form_validation->set_rules($config);
if($this->form_validation->run() == FALSE){
$data['errors']=validation_errors();
} else {
$data=array(
'username'=>$_POST['username'],
'password'=>$_POST['password'],
'user_type'=>$_POST['user_type']
);
$this->load->model('user');
$userid=$this->user->create_user($data);
$this->session->set_userdata('userID',$userid);
$this->session->set_userdata('user_type',$_POST['user_type']);
redirect(base_url().'posts');
}
}
$this->load->helper('form');
$this->load->view('header');
$this->load->view('register_user');
$this->load->view('footer');
}
我开始使用 Codeigniter，但找不到问题...
最佳答案
问题是在某些情况下$errors变量未创建。使用if(isset($errors) && $errors))
实际上在 View 中您需要的是 <?php echo validation_errors(); ?> ，无需将其分配给变量
看看http://ellislab.com/codeigniter/user-guide/libraries/form_validation.html有关如何显示错误的更多信息
