控制器文件welcome.php

PHP复制代码

class Welcome extends Controller {
 
    Public $domain;
    function Welcome()
    {
        parent::Controller();
        $this->domain    = (substr($_SERVER['HTTP_HOST'], 0, 4)=="www.")?str_replace("www.", "", $_SERVER['HTTP_HOST']):$_SERVER['HTTP_HOST'];    
        echo $this->domain;
    }
   
    function index($domain)
    {
        $this->load->model('get_info');
        $info    =    $this->get_info->get_infos($domain);
 
        //$this->load->view('welcome_message');
    }
}

复制代码

模型文件：Get_info.php

PHP复制代码

class Get_info extends Model
{
    function Get_info()
        {
            parent::Model();    
        }
 
    function get_infos($domain)
        {    
            echo $domain;
            $query = $this->db->get('whyparking_domains');
            //return $query->result();
        }
}

复制代码

index 你给参数了吗？需要通过 index.php/welcome/index/参数  来给
