Codeigniter redirect not working
提问by el_pup_le
Why isn't redirect working here. I'm getting call to undefined function redirect().
为什么重定向在这里不起作用。我正在调用未定义的函数重定向（）。
class Login extends CI_Controller {
function index() {
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
$this->load->view('login_view');
}
function authenticate() {
$this->load->model('user_model');
$query = $this->user_model->authenticate();
if($query) {
$data = array(
'username' => $this->input->post('username'),
'is_logged_in' => true
);
$this->session->set_userdata($data);
redirect('/site/news_feed');
}
else {
$this->index();
}
}
}

Change the top portion above your authenticate()method to this...
将authenticate()方法上方的顶部更改为此...
class Login extends CI_Controller {
function __construct()
{
// this is your constructor
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
}
function index()
{
//this is only called when someone does not specify a method...
$this->load->view('login_view');
}
...
I would strongly recommend moving these two helpers to be autoloaded because of their almost manditory use...
我强烈建议将这两个助手移动到自动加载，因为它们几乎是强制性的使用......

Try:
尝试：
function __construct() {
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
}
If your server is windows, try:
如果您的服务器是 Windows，请尝试：
redirect('/site/news_feed','refresh');

You're not loading the URLhelper in the authenticatemethod. You'll have to either add $this->load->helper('URL')to the class constructor (which it looks like you were trying to do), or you'll have to add that to the authenticate method itself.
您没有URL在authenticate方法中加载助手。您要么必须添加$this->load->helper('URL')到类构造函数（看起来您正在尝试这样做），要么必须将其添加到身份验证方法本身。
Just a reminder, the indexmethod is a special method -- it is called when no other method is specified. With the URL <your domain>/login/, index will be fired. Other than that, it will be ignored.
提醒一下，该index方法是一种特殊方法——当没有指定其他方法时会调用它。使用 URL <your domain>/login/，索引将被触发。除此之外，它将被忽略。

Your logic is inda right but, there are a couple of shortcomings when you load some helpers and models in the constructor sometimes.
您的逻辑是正确的，但是，有时在构造函数中加载一些帮助程序和模型时存在一些缺点。
Try to load the helper from within the function.
尝试从函数内部加载助手。

You need to place
你需要放置
$this->load->helper('url');
before your redirect function.
在您的重定向功能之前。
回答by Abdul Manan
redirect() belong to url helper.
You can load it like this each time you need it.
您可以在每次需要时像这样加载它。
$this->load->helper('url');
or better to load it globally so you don't need to load it again and again
或者更好地全局加载它，这样你就不需要一次又一次地加载它
//application/config/autoload.php
$autoload['helper'] = array("url");
