CodeIgniter Anchor错误：在此服务器上找不到URL [英] CodeIgniter Anchor error: URL not found on this server

问题描述

我已经花了好几个小时才能建立一个简单的锚点链接，但没有成功。

我的控制器是

  class Welcome extends CI_Controller {
 public function index（）
 {
 $ this-> load-> view （'模板'）; 
} 
 
 public function contact（）
 {
 $ this-> load-> view（'contact'）; 
} 
} 
  

My template.php view基本上是一个有

 < a class =menuhref> <？php echo anchor（'welcome / contact /'，'Contato'）？> < / a> 
  

我在views目录中有一个contact.php。

我的 config.php 是

  $ config ['base_url'] ='localhost'; 
 
 $ config ['index_page'] ='index.php'; 
  

加载 template.php 点击链接contato我想驱动系统到函数 contact（），负责打开页面 contact.php 。但是，我有以下错误：

/ localhost / index.php / welcome / contact / p>

缺少什么？

解决方案

base_url config MUST 包含协议和尾部斜杠。 / p>

从 config.php 档案：

您的CodeIgniter根的URL。通常，这将是您的基本URL，

带有斜杠：

  http：//示例。 com / 
  

如果没有设置，CodeIgniter会猜测协议，域
$ b $

因此，您可以设置 base_url 如下，或在这种情况下，只需将其留空：

  $ config ['base_url'] ='http：// localhost /'; 
 
＃base_url应该是绝对的，如果你在子文件夹中安装了CI：
 $ config ['base_url'] ='http：// localhost / path / to / codeigniter_folder / '; 
  

边注：，以便使用URL辅助函数code> anchor（），首先加载助手文件： $ this-> ）; （或通过 autoload.php 配置文件自动加载助手）

---

为什么 base_url 配置会影响 anchor $ c> function？

anchor（） 函数，使用 site_url（） 帮助函数来确定URL地址的超链接。

和 site_url（） 本身，使用两个 base_url 和 index_page



因此，如果您为 base_url 和/或 index_page configs， anchor（）函数将无法正常工作。

I have been for hours to make a simple anchor link working without success.

My controller is

class Welcome extends CI_Controller {
    public function index()
    {
        $this->load->view('template');
    }

    public function contact()
    {
        $this->load->view('contact');
    }        
}

My template.php view is basically a file with

<a class="menuhref"> <?php echo anchor('welcome/contact/','Contato')?> </a>

I also have a contact.php in the views directory.

My config.php is

$config['base_url']   = 'localhost'; 

$config['index_page'] = 'index.php';

When the template.php loads and I click in the link "contato" I would like to drive the system to the function contact() that would be responsible to open the page contact.php. However, I have got the following error:

"/localhost/index.php/welcome/contact" was not found on this server

What is missing?

解决方案

The base_url config MUST contains the protocol and a trailing slash as well.

From the config.php file:

URL to your CodeIgniter root. Typically this will be your base URL,
WITH a trailing slash:

http://example.com/

If this is not set then CodeIgniter will guess the protocol, domain
and path to your installation.

Hence, you could set the base_url as follows, or in this case simply leave it blank:

$config['base_url'] = 'http://localhost/';

# base_url should be absolute, If you've installed CI in sub-folder:
$config['base_url'] = 'http://localhost/path/to/codeigniter_folder/';

Side-note: in order to use URL helper functions such as anchor(), load the helper file at first: $this->load->helper('url'); (or load the helper automatically via autoload.php config file).

---

Why does base_url config affect anchor() function?

anchor() function, uses site_url() helper function to determine the URL address of the hyperlink.

And the site_url() itself, uses two base_url and index_page configs to create the URL address.

Hence if you assign a wrong value to base_url and/or index_page configs, the anchor() function won't work properly.
