如何从codeigniter中显示内容从数据库，而不从调用控制器从视图？ [英] how to display content from database in codeigniter without calling controller from view?

问题描述

我是新的codeigniter。我按照视频教程并成功创建了登录注册系统。注册或登录后，用户访问一个名为members.php的页面。

members.php是一个视图。

我的控制器是main.php，模型是model-users.php。

我希望members.php显示/拥有数据库中的内容，它一旦登录或注册？

我在网上的几个资源，说不从控制器的视图。

感谢

解决方案

我认为 CodeIgniter文档实际上很清楚，很容易遵循。

控制器：

pre> <？php if（！defined（'BASEPATH'））exit（'不允许直接脚本访问）;

类成员扩展CI_Controller {
function __construct（）{
parent :: __ construct（）;

$ this-> load-> model（'members_model'）;
}

function index（）{
$ data ['members'] = $ this-> members_model-> get_members

$ this-> load-> view（'header'，$ data）;
$ this-> load-> view（'members'）;
$ this-> load-> view（'footer'）;
}
}


模型 p>

 <？php if（！defined（'BASEPATH'））exit（'不允许直接脚本访问）; 
 
 class Members_model extends CI_Model {
 
 function get_members（）{
 $ query = $ this-> db-> get（'members'）; 
 return $ query-> result_array（）; 
} 
} 
  

查看 p>

 <？php 
 
 print_r

要访问上述页面， a href =http://yoursite.com/index.php/members> http://yoursite.com/index.php/members 。

您可以使用 .htaccess 文件从URI中删除 index.php 段。当您运行控制器时， index（）方法会自动调用。

I am new to codeigniter. I followed a video tutorial and successfully created a login registration system. After registration or login the users reach a page called members.php.

members.php is a view.

my controller is main.php and model is model-users.php.

I want members.php to show/have content from the database so that the users can read it once the login or register?

I followed a few resources on the web that said not to call controller from view. How can I accomplice the above without doing so?

Thanks

解决方案

I think the CodeIgniter documentation is actually very clear, and very easy to follow. Nevertheless, here's an example of how you might structure your app.

Controller:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Members extends CI_Controller {
    function __construct() {
        parent::__construct();

        $this->load->model('members_model');
    }

    function index() {
        $data['members'] = $this->members_model->get_members();

        $this->load->view('header', $data);
        $this->load->view('members');
        $this->load->view('footer');
    }
}

Model:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Members_model extends CI_Model {

    function get_members() {
        $query = $this->db->get('members');
        return $query->result_array();
    }
}

View:

<?php

print_r($members);

---

To access the above page, you would visit http://yoursite.com/index.php/members.

You can use a .htaccess file to remove the index.php segment from the URI. The index() method is automatically called when you run a controller.
