codeigniter uri段无法正常工作，输出为0 [英] codeigniter uri segment not working properly getting output as 0

问题描述

localhost/backend/administrator/authentication/8218/0

在codeigniter中，我想获取这些值8218和0.

In codeigniter, I want to fetch these values 8218 and 0.

我的代码是:

class Administrator extends Controller {

function Administrator()
    {
            parent::Controller();
            $this->load->library('uri');
    }

function authentication()
    {        
        echo $seg1= $this->uri->segment(3);
        echo $seg2 = $this->uri->segment(4);
        echo $this->uri->total_segments(); 
    }

}

我没有得到任何输出，但是当我使用 $ this-> uri-> total_segments();

I am not getting any output, but I got out put as '0' when I used $this->uri->total_segments();

my config.php 

'AUTO'          Default - auto detects
| 'PATH_INFO'       Uses the PATH_INFO
| 'QUERY_STRING'    Uses the QUERY_STRING
| 'REQUEST_URI'     Uses the REQUEST_URI
| 'ORIG_PATH_INFO'  Uses the ORIG_PATH_INFO
|

$config['uri_protocol'] = "AUTO";

i am using .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /backend/

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]    

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 /index.php
</IfModule> 

任何人都能找出我的错误并建议我正确的代码.

Can any one find out my mistake and suggest me the correct code.

推荐答案

您不需要加载核心库.它已为您自动加载.从构造函数中删除以下行，一切都应该正常工作.

You don't need to load the core library. It has been loaded automatically for you. Remove the following line from the constructor, and everything should be working.

$this->load->library('uri');
