MongoDB和CodeIgniter [英] MongoDB and CodeIgniter

问题描述

任何人都可以帮助指导我的教程，图书馆等，这将允许我使用CodeIgniter的MongoDB。

Can anyone assist in pointing me to a tutorial, library, etc. that will allow me to work with MongoDB from CodeIgniter?

任何帮助真的很感激。 / p>

Any help is really appreciated.

推荐答案

我不知道它的CodeIgniter方法，但我创建了一个CodeIgniter库扩展Mongo类额外

I'm not sure if its the "CodeIgniter way" but I created a CodeIgniter library that extends the Mongo class with an extra property to store the current database connection.

这里是我项目的相关代码文件。

Here are the relevant code files from my project.

config / mongo.php

$config['mongo_server'] = null;
$config['mongo_dbname'] = 'mydb';

libraries / Mongo.php

class CI_Mongo extends Mongo
{
    var $db;

    function CI_Mongo()
    {   
        // Fetch CodeIgniter instance
        $ci = get_instance();
        // Load Mongo configuration file
        $ci->load->config('mongo');

        // Fetch Mongo server and database configuration
        $server = $ci->config->item('mongo_server');
        $dbname = $ci->config->item('mongo_dbname');

        // Initialise Mongo
        if ($server)
        {
            parent::__construct($server);
        }
        else
        {
            parent::__construct();
        }
        $this->db = $this->$dbname;
    }
}

和一个示例控制器

controllers / posts.php

class Posts extends Controller
{
    function Posts()
    {
        parent::Controller();
    }

    function index()
    {
        $posts = $this->mongo->db->posts->find();

        foreach ($posts as $id => $post)
        {
            var_dump($id);
            var_dump($post);
        }
    }

    function create()
    {
        $post = array('title' => 'Test post');
        $this->mongo->db->posts->insert($post);
        var_dump($post);
    }
}
