I am having trouble converting the statement to php
Here is the structure of the data:
db.rooms.find({"_id" : "1620888265"}).pretty();
{
"_id" : "1620888265",
"start" : 1620988265,
"end" : null,
"users" : [
{
"name" : "owner",
"score" : 0.9,
"singin" : 1620895469
},
{
"name" : "user",
"singin" : 1620895769
}
],
"questions" : [
{
"id": 1
"title" : "X",
"released" : false
}
]
}
Here the command that works for me:
db.rooms.updateOne({"_id" : "1620970325obn","questions.ident":2},{$set : {"questions.$.released":true,"questions.$.time":'1415'}});
Once translated to PHP (not working for me):
$rooms_db->updateOne(array("_id" => $room,"questions.ident"=>$ident), array ('$set'=>array('questions.$.released' => true,'questions.$.time'=>$time)));
The problem has been that the variable "$ident" was a number, but for some reason PHP treated it as a String. This can be seen with var_dump ($ident) .
"questions.ident"=>(int)$ident), this fixed the problem

I've got JSON output that comes to me like this
{ [objects{}] [to] [from] [total] }
and due to the API I'm pulling this from I can only pull 500 records at a time, what I'm trying to do is merge the objects part of multiple json outputs into a larger recordset.
I've tried using array_merge with json_encode and json_decode but it's not working, I'm assuming it's because of the other arrays (to/from/total) that are impacting my ability to merge.
Any idea how I could go about this, I was thinking of a line by line merge, but issue with this is different types of arrays have different elements (I'm only trying to merge arrays with the same elements).
Edit: hmmm json formatting didn't come through well even with code tags

You have 4 elements in the given json, object to from and total
I am assuming, you hav to merge the object from two JSONs, get minimum value of from, get maximum value from to and sum of total
function my_merge($json_1,$json_2){
$array_1 = json_decode($json_1,true);
$array_2 = json_decode($json_2,true);
return ['objects'=>array_merge($array_1['objects'],$array_2['objects']),'from'=>min($array_1['from'],$array_2['from']),'to'=>max($array_1['to'],$array_2['to']),'total'=>($array_1['total']+$array_2['total'])];
}
Above, first, json_decode with second parameter true to decode and convert JSON to array.
Second, merge the index [0] of both $array_1 and $array_2 as it contains the object. Do the min max and summation for total and return the resultant array.

I am stuck at a point where i need to sort the documents based on the date time field following is my database structure
"_id" : ObjectId("59199bbb05b505777d86e9a2"),
"Email" : "sk.sagarkhan95#gmail.com",
"BlogPosts" : [

Now i want to sort the documents in descending order based on Date in the BlogPosts array.
In Mongodb Console i tried
db.Timeline.find().sort({BlogPosts.Date : -1 }).pretty()
But In PHP i am not able to do this
I tried
$cursor = $collection->find()->sort(array("BlogPosts"=>array("Date"=> -1)));
and
$cursor = $collection->find()->sort(array("BlogPosts.$.Date"=> -1 ));
I also tried the solution mentioned in this answer but no luck... Please help me out
Instead of:
sort(array("BlogPosts.$.Date"=> -1 ));
try
sort(array("BlogPosts.Date"=> -1 ));
Refer this question
I have a field which stores an array of objects. I want to modify the object's "status" value depending on the "id" value the object possesses.
"authors" : [
{
"id" : "18",
"first_name" : "Buddhika",
"last_name" : "Chathuranga",
"$$hashKey" : "object:35",
"status" : NumberLong(0)
},
{
"id" : "3", // search for this number
"first_name" : "Pasindu",
"last_name" : "Priyanath",
"$$hashKey" : "object:43",
"status" : NumberLong(0) // modify this to 1
}
],
We can leverage positional update in MongoDB to update values inside array.
Mongo Positional Update
Please find script below.
db.authors.update(
{"authors.id": "3"},
{ $set: { "authors.$.status" : NumberLong(1) }}
)
Update in Mongo DB php:
db.collection.update( criteria, objNew, upsert, multi );

I'm using Codeigniter 3.0.6, with this MongoDB Library https://github.com/intekhabrizvi/Codeigniter-mongo-library
What i'm trying to do is to update fields in a subdocument of this following committees array with ObjectId("570f6e08407729ec3000002b")
{
"_id" : ObjectId("570f4a94407729d42e00002e"),
"name" : "Test Community",
"committees" : [
{
"_id" : ObjectId("570f6e08407729ec3000002b"),
"name" : "2016",
"start" : ISODate("2016-01-17T00:00:00.000Z"),
"end" : ISODate("2016-12-12T00:00:00.000Z"),
"join_state" : 1,
"state" : 1
},
{
"_id" : ObjectId("570f6e08407729ec3000002c"),

"end" : ISODate("2017-12-12T00:00:00.000Z"),
"join_state" : 1,
"state" : 1
}

But using above library or can you suggest me some other way to make it work right. Please don't mention mongodb command lines, as i'm aware about it. So it would be great if you can help me with PHP code, or codeigniter way is very much appreciable.
{
"__v" : 2,
"_id" : ObjectId("54dc4fd10ac1f6a066a0646c"),
"desc" : "test1",
"lists" : [
{
"index" : 1,
"text" : "__point",
"_id" : ObjectId("54dc4fda0ac1f6a066a0646d"),
"createdAt" : ISODate("2015-02-12T07:01:46.390Z")
},
{
"index" : 2,
"text" : "__point",
"_id" : ObjectId("54dc4fdd0ac1f6a066a0646e"),
"createdAt" : ISODate("2015-02-12T07:01:49.668Z")
}
],
"name" : "test" }
The test array looks like this. i want to add 'category' field and add value '0' in lists checking _id.
i tried
$collection->update(array('_id' => new MongoId("54dc4fd10ac1f6a066a0646c")),array('$set' => array(new MongoId("54dc4fda0ac1f6a066a0646d").".lists.category" => '0')));
like this but it doesn't work.
set third parameter of update to true.
i think there is some problem in finding which embedded document for updated.
try this one might be work.
$collection->update(array('_id' => new MongoId("54dc4fd10ac1f6a066a0646c"), 'lists._id' => "54dc4fda0ac1f6a066a0646d"), array('$set' => array("lists.$.category" => '0')), true);
Hi I don't know more about PHP but you can do this from following script
db.collectionName.find({
"lists": {
"$exists": true
}
}).forEach(function(data){
for(vari=0;i<data.lists.length;i++){
db.collectionName.update({
"_id": data._id,
"lists.index": data.lists[
i
].index
},
{
"$set": {
"lists.$.category": 0
}
},
true,
true);
}
})
