'Firebase realtime database configure rules

Is there a way to set the value of a key to null therefore delete it, if its new value is 0. For instance:

  "totalGames": {
    "ps5": 15,
    "ps4": 10,
    "ps3": 0
  }

I am using increment(delta) to update the values and it can be a negative value, that's why I want to set the rule. I didn't find a solution anywhere, does anyone have a suggestion?

You can send the parameters through the URL to the other page...

For example, your URL when you call the other page can be of the following format:

www.myurl.com?name=JANE&[email protected]

In the other page, make sure you check to see if there are any parameters included in the URL, and do the corresponding action.
