mongodb-php

Here's my MongoDB collection: { "_id" : ObjectId("515d8f53175b8ecb053425c2"), "category" : "Batteries", "products" : [ { "brand" : "Duracell", "item" : [ "AA", "AAA" ] }, { "brand" : "Everyday", "item" : [ "9V", "AA", "12V" ] } ] } The output that I need is 1) Unique list of all items {["AA", "AAA", "9V", "12V"]} and 2. unique list of items per product { "category" : "Batteries", "item": ["AA", "AAA", "9V", "12V"] } I'm very new to MongoDB, and I tried different aggregations functions and nothing seems to work. Please help. Ananth After few more tries, I had solved this. Here's the commands:

I'm using the Mongo PHP extension. My data looks like: users { "_id": "4ca30369fd0e910ecc000006", "login": "user11", "pass": "example_pass", "date": "2010-09-29" }, { "_id": "4ca30373fd0e910ecc000007", "login": "user22", "pass": "example_pass", "date": "2010-09-29" } news { "_id": "4ca305c2fd0e910ecc000003", "name": "news 333", "content": "news content 3333", "user_id": "4ca30373fd0e910ecc000007", "date": "2010-09-29" }, { "_id": "4ca305c2fd0e910ecc00000b", "name": "news 222", "content": "news content 2222", "user_id": "4ca30373fd0e910ecc000007", "date": "2010-09-29" }, { "_id":

I might be a bit in over my head on this as I'm still learning the ins and outs of MongoDB, but here goes. Right now I'm working on a tool to search/filter through a dataset, sort it by an arbitrary datapoint (eg. popularity) and then group it by an id. The only way I see I can do this is through Mongo's MapReduce functionality. I can't use .group() because I'm working with more than 10,000 keys and I also need to be able to sort the dataset. My MapReduce code is working just fine, except for one thing: sorting. Sorting just doesn't want to work at all. db.runCommand({ 'mapreduce': 'products',

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

How can I query a specific month in mongodb, not date range, I need month to make a list of customer birthday for current month. In SQL will be something like that: SELECT * FROM customer WHERE MONTH(bday)='09' Now I need to translate that in mongodb. Note: My dates are already saved in MongoDate type, I used this thinking that will be easy to work before but now I can't find easily how to do this simple thing. JohnnyHK You can do that using aggregate with the $month projection operator: db.customer.aggregate([ {$project: {name: 1, month: {$month: '$bday'}}}, {$match: {month: 9}} ]); With

I'm trying to calculate the skip value for a given record in a mongo db collection using the php driver. So taking a given record, find out the index of that record within the entire collection. Is this possible? Currently I'm selecting all records and manually doing an index of on the array of results. This is called "forward paging" which is a concept you can use to "efficiently page" through results in a "forward" direction when using "sorted" results. JavaScript logic included (because it works in the shell), but not hard to translate. The concept in general: { "_id": 1, "a": 3 }, { "_id":
