MongoDB find then update - PHP

Question

I have a document that looks like

{
  _id: ObjectId("someId"),
  recipients: [
    {
      email: "emailaddress"
    },
    {
      email: "email2"
    }
  ]
}

I am trying to update the first recipient object, and add another property but to no avail.

{
  _id: ObjectId("someId"),
  recipients: [
    {
      email: "emailaddress",
      new_prop: "something"
    }
  ]
}

Is there a way to do this with findOneAndUpdate? I am using PHP

Answer 1

I did some research. I'm new to MongoDB so I'm relying on my fellow developers to validate this code. I'm thinking this will do the trick:

$mongoID = new MongoID('yourID');
$newdata = array('$set' => array("recipients.0.new_prop" => "Something"));
$collection->update(array("_id" => $mongoID), $newdata);
