Inserting multiple json elements into MongoDB database

Question

I have connected my php web app to mongodb with the help of codeigniter driver. Trying to inserting multiple json elements into database as below.

"ticket" : [
     {
     "problem" : "testing",
     "time_taken" : "5 hrs",
     "number_of_visits" : "7",
     "expenses" : {
             "amount" : "2000",
             "distance_travelled" : "4 km"
              }
     },
     {
     "problem" : "testing",
     "time_taken" : "5 hrs",
     "number_of_visits" : "4",
     "expenses" : {
             "amount" : "2500",
             "distance_travelled" : "5 km"
              }
     }
]

What is the query I have to use for this?

Answer 1

$this->mongo_db->where('_id', new MongoId($id))->push("ticket",$data)->update('engineer');

This is the query I'm using for inserting multiple array values in mongodb codeigniter.
