How to check if the username or the email already exists

Hello, how can I check if the Email or the username already exists and give seperate error messages?

TL;DR

Developers are trying to check if the email or username already exist by creating a function that triggers after each user change to insert values into a separate collection and then verify uniqueness. Wrap the creation process in a `try/catch` block, catch the error, and display a custom message when error `409` occurs to differentiate between existing email and username.

Hi A. As of now username is not available for Appwrite users. B. You'll need to wrap it with a try/catch block, capture the error by yourself if so for the `create` method, then if you get an error `409` it means the user already exist and you can show a custom error message for the user.

sorry i mean name not username

Name is not unique and two users can have the same name

my problem is just that if i do a try catch it just says that one of them already exists but i dont know which of them

That's good

but i want it to be unique (app side)

TypeScript

try {
                  await account().create(
                    userId: ID.unique(),
                    email: email,
                    password: password,
                    name: _usernameController.text,
                  );
                } catch (error) {
                  final appwriteError = error as AppwriteException;

                  throw Exception(appwriteError.message);
                }```

What you mean one of them, you're creating many in a loop?

theres an input for email and for username (name)

if the name already exists it says this: Error: Exception: A user with the same id, email, or phone already exists in this project. if the email already exists it says this: Error: Exception: A user with the same id, email, or phone already exists in this project.

For this, the best would be to create a function that will run (trigger) after each user change You'll need to create another Collection with the current user name

So the flow can be like so

When the user is setting his name for the first time, you then, insert that value into the usernames collection.
When the user is updating his name, the function checks if that username is taken, if so it will change it to the old one back
