Just a quick question. How can you prevent an entry in firebase being added with an error. In your example it provides an error message when the phone number is not entered but it still writes to the realtime database.
You just need to check by an if statement. If all of the fields are filled by the user then the data will be sent otherwise a message will be displayed
is there a way to have a lot of data in realtime database and show in the app; but the condition is that each day the data that is showed in the app have to be updated for the next id. For example: The id = 1 , shows apple, but the next day the id have to be 2, and shows pineapple, all the data is in firebase. Is it posible my query ?
Hello. Firebase is a database and as other databases holds the data that you send to it. the database will send you exactly your data without any changes. Therefore the changes should be manage in the app that you are developing.
