localhost/backend/administrator/authentication/8218/0

在codeigniter中，我想获取这些值8218和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，但当我使用$this->uri->total_segments();

时，我得出'0'

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.

任何人都可以发现我的错误并建议我正确的代码。

Answer 1

您无需加载核心库。它已自动加载给您。从构造函数中删除以下行，一切都应该正常工作。

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

Answer 2

加载$this->load->helper('url'); Codigniter使用控制器/方法/ param / param。所以你可以像这样访问这些值。

 function authentication($first_calue = '0', $second_value='0')
        {        
            echo $seg1= $this->uri->segment(3);
            echo $seg2 = $this->uri->segment(4);
            echo $this->uri->total_segments(); 
            echo $first_calue;
            echo $second_value;

        }

Answer 3

如果你总是有这个控制器方法的url结构，我会建议你使用方法参数。控制器方法通常处理url段的方式是将它们声明为方法参数：

public function method_name($agr_1 = 0, $arg_2 = 0)

这里$ arg_1将持有8218，$ arg_2 - 0

Answer 4

您无需在codeignitor中调用库只需启动代码 $this->uri->segment(3);

codeigniter uri段无法正常工作，输出为0
