    We usually have this kind of error while making query with mongodb "Uncaught exception 'MongoException' with message 'Invalid object ID'" , the main reason behind this kind of error is that :->

    a) Id string for mongodb must be 24 hexadecimal characters. If an invalid string is passed to this constructor, the constructor will ignore it and create a new id value.

    Thus to solve this kind of error we can try something like this :

    1. $_id = "-6";
    2. try {
    3.     $_id = new MongoId($_id);
    4. } catch (MongoException $ex) {
    5.     $_id = new MongoId();
    6. }
