I want to do group by with email_address field in mongodb in php, here is my code for this but it is not working, can anyone please look into that and give me proper solution for that ?
$m = new MongoDB\Client("mongodb://localhost:27017");
$db = $m->mailchimp;
$collection = $db->users;
$aggregate[] = [
'$group' => [
'_id' => 'email_address',
'email_address' => array('$sum'=>'1'),
],
];
$data=$collection->aggregate($aggregate);
I think you are missing $ in query.
'_id' => '$email_address',
'$email_address' => array('$sum'=>'1')

In mongo shell the query:
db.collections.distinct('user_id');
simply gives the distinct documents.
I am working on phalcon and there is no option like
Collections::distinct()
So how do i query distinct in phalcon. Please help me
Perhaps Phalcon's answer in the forum could help: https://forum.phalconphp.com/discussion/6832/option-for-function-distinct-phalconmvccollection
They suggest using aggregations:
$data = Article::aggregate(
array(
array(
'$project' => array('category' => 1)
),
array(
'$group' => array(
'_id' => array('category' => '$category'),
'id' => array('$max' => '$_id')
)
)
)
);
Hi i am working on backend of web application & want to find the documents from mongodb database that contain key active_status with value set to both 1 & 2. With mongodb PHP i am confused of how to find with both parameters in single query.
My query was this:
$mongoDb = MongoDbConnector::getCollection("endusers");
$endUserData = $mongoDb->find(array('active_status' => 1, '$and' => array('active_status' => 2)));
I have to fetch the users whose active_status should be 1 & 2. The above query doesnt seems to work. What is the right one for that?
Thanks on advance for quick response.
You have $and the wrong way around. Both arguments need to be included:
$endUserData = $mongoDb->find(array(
'$and' => array(
array( 'active_status' => 1 )
array( 'active_status' => 2 )
)
));
And since that would only make sense when looking for both elements within an array element, then you should instead use $all, which is shorter syntax:
$endUserData = $mongoDb->find(array(
'active_status' => array( '$all' => array(1,2) )
));
I should add that unless you intend to match a document like this:
{ "active_status" => [1,2] }
The you do not in fact want $and at all, but rather you want $or or better yet $in for multiple possible values on the same field:
$endUserData = $mongoDb->find(array(
'active_status' => array( '$in' => array(1,2) )
));
This matches documents like this:
{ "active_status": 1 },
{ "active_status": 2 }
The following is the json array I have in a collection called claims in MongoDB.
{
"xmllisting_id": "537f371fb2e380922fff0e2c",
"pharmacyfiles_id": "537f3402b2e380732aa6032d",
"claim": {
"MemberID": "097110330047532601",
"PatientShare": "0",
},
"modified": ISODate("2014-05-23T13:12:17.191Z"),
"created": ISODate("2014-05-23T13:12:17.192Z")
}
I need to find all claims with a specified MemberID.I have tried the following in CakePHP without any success.
$claims = $claimobj->find(
'all',
array(
'conditions' => array(
'claim' => array('MemberID' => '097110330047532601')
)
)
);
How can I do it?
Finding "nested" details in MongoDB usually requires "dot notation". Otherwise you are actually asking for an object that has "exactly" the key and "only" the key you are specifying to match. Which of course it does not, as there is more information there:
$claims = $claimobj->find(
'all',
array(
'conditions' => array(
'claim.MemberID' => '097110330047532601'
)
)
);
So the path is "claim.MemberID" and not 'claim' => array('MemberID' => '097110330047532601' ) as you have written.
Is there a way to perform a raw query (just as you can do with MySQL) in Doctrine with MongoDB?
I'm trying to do this:
db.report.aggregate([{"$group" : {_id:"$content", count:{$sum:1}}}])
It doesn't seem to be a native aggregate function in Doctrine either, is it?
Following did the trick for me
$dbName = $this->container->getParameter('mongo_db_name');
$connection = $this->container->get('doctrine_mongodb')->getConnection();
$mongo = $connection->getMongo();
$db = $mongo->selectDB($dbName);
$results = $db ->command([
'aggregate' => 'report',
'pipeline' => [
['$group' => ['_id' => '$content', 'count' => ['$sum' => 1]]]
]
]);
return $results;
Not sure about native Doctrine function, but in case of aggregations I'd prefer to have RAW JSON output, because it's mostly used to render out some charts.
I needed to use an advanced version of a $lookup stage, but sadly, didn't because its lookup() method adds just a basic version of a stage like:
public function getExpression(): array
{
return [
'$lookup' => [
'from' => $this->from,
'localField' => $this->localField,
'foreignField' => $this->foreignField,
'as' => $this->as,
],
];
}
An obvious solution would be to provide a custom version of Stage/Lookup.php class, but I didn't want to create a separate file for such a small thing, so I decided to go with inline class:
$lookupExpr = [
'$lookup' => [...],
];
$aggregationBuilder->addStage(new class($lookupExpr, $aggregationBuilder) extends Aggregation\Stage {
public function __construct(private array $lookupExpr, Builder $builder) {parent::__construct($builder);}
public function getExpression(): array
{
return $this->lookupExpr;
}
});
In Doctrine ODM 2.0, the underlying connection is handled by the mongodb/mongodb package instead of doctrine/mongodb. As such, you can get the connection though doctrine ManagerRegistry::getConnection(), then use the command function using the mongodb library:
use Doctrine\Bundle\MongoDBBundle\ManagerRegistry;
class Test {
function execute(ManagerRegistry $mr) {
$database= $mr->getConnection()->db_name;
$cursor = $database->command([
'geoNear' => 'restos',
'near' => [
'type' => 'Point',
'coordinates' => [-74.0, 40.0],
],
'spherical' => 'true',
'num' => 3,
]);
$results = $cursor->toArray()[0];
var_dump($results);
}
}
In my case i use aggregation
$db = $mongo->selectDB('ostrov_sync');
$dbTable = $mongo->selectCollection($db, 'sync_task');
$results = $dbTable->aggregate([
[
'$match' => [
'payloadHash' => [
'$eq' => '0000cfdc-c8cf-11e9-9485-000c29d1ed7a',
],
],
]
]);
dump(results);
I finded a data my mongodb database. I want be update a array's field this data.
My data is here:
http://paste.ubuntu.com/8447715/
I want will find this data and update home adress. I am trying:
$Data = array(
'$set' => array(
'address.name' => 'home'
)
); <br>
$users->update(array('username' => 'micheal', 'address.name' => 'hame') ,$Data);
What's wrong ?
My english is bad,sorry
You need to use the $ operator to update the address that matches the selection;
$Data = array(
'$set' => array(
'address.$.name' => 'home'
)
);
$users->update(array('username' => 'micheal', 'address.name' => 'hame') ,$Data);
