MongoDB and CodeIgniter [closed]

Answer 1

I like Stephen Curran's example as it is simple and allows an interface to Mongo without too much functionality written within Php, I tend to find huge abstraction clases a bit much at times for what I am after.

I have extended his example to include database authentication. Go here: http://www.mongodb.org/display/DOCS/Security+and+Authentication to read about mongo authentication, don't forget to enable authentication for the Mongo Server you are connecting to.

I have also changed the old style constructor function to be __construct and am handling Mongo Connection Exceptions as they can reveal your username and password.

config/mongo.php

libraries/Mongo.php

load->config('mongo');

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

        // Initialise Mongo - Authentication required
        try{
            parent::__construct("mongodb://$username:$password@$server/$dbname");
            $this->db = $this->$dbname;
        }catch(MongoConnectionException $e){
            //Don't show Mongo Exceptions as they can contain authentication info
            $_error =& load_class('Exceptions', 'core');
            exit($_error->show_error('MongoDB Connection Error', 'A MongoDB error occured while trying to connect to the database!', 'error_db'));           
        }catch(Exception $e){
            $_error =& load_class('Exceptions', 'core');
            exit($_error->show_error('MongoDB Error',$e->getMessage(), 'error_db'));           
        }
    }
}
