This evening I started work on an active record inspired library for interacting with MongoDB via a CodeIgniter library.
So far I’ve got searching and inserting working. Updating and deleting are going to take more time because they’re a bit trickier.
What this means is you can easily work with a database collection like so:
$this->mongo_db->where_gte('age', 18)->where(array('country' => 'UK', 'can_drink' => TRUE))->get('people');
$this->mongo_db->get_where('posts', array('title' => 'Hello, World!');
I’ve created a repository on Bitbucket located at http://bitbucket.org/alexbilbie/codeigniter-mongo-library. If you have a look at the README file there is an overview of what is there so far and also what needs doing (and some maybes!).
Hope people find it useful.
