How can i execute a mongodb query in php (codeigniter framework) - php

Question

This is my MongoDB query
db.getCollection('fe_report').aggregate([{
$match:
{ date: { $gte: ISODate("2017-07-01T00:00:00.000Z"),
$lte: ISODate("2017-07-19T00:00:00.000Z")} } },
{
$group:
{
_id :"$employee_id_fk",
no_of_kms : {$sum: "$no_of_kms"},
no_of_orders: {$sum: "$no_of_orders"},
}
}
]
)
i need to execute this query from PHP

Answer 1

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;
}
}
And a sample controller
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);
}
}
try this it work for u

You can use the aggregate function for grouping the fields by ID and computing sum for any columns (only for integer type)
$from = $from.".000Z"; // if you need to filter by date range
$to = $to.".000Z"; // from date and to date("2017-07-22 00:00:00.000Z")
$where = array( array(
'$match' => array(
'date' => array(
'$gte' => new MongoDate(strtotime($from)),
'$lte' =>new MongoDate(strtotime($to)))
)
),
array(
'$group' => array(
'_id' => '$employee_id_fk', // grouping by ID
'no_of_kms' => array(
'$sum' => '$no_of_kms' ' // summing up the KM's fields for the grouped columns
),
'no_of_orders' => array(
'$sum' => '$no_of_orders
)
)
)
);
$data = $this->maggregate('fe_report',$where); // passing it to the maggregate function
// maggregate function()
public function maggregate($table, $where){
$mdb = new MongoClient("localhost"); // establishing mongodb connection
$connect = $m->selectDB("examples")->selectCollection($table);
$result = $connect->aggregate($where);
connect->close();
return $result;
}
