Hi
How can I check for new data if a contribution already exists?
So that I prevented duplicate entries.

Not sure what you want to achieve. Depending on the data you require for registration you could check on email address etc.
ie.:
I have an e-mail database. When I enter a new email, I want to check if it’s already in the database. Not that I make duplicate entries.
Put a unique key on your table for the email field.
Then I get an error while saving?
You can set up a custom error message that tells the user: That email already exists.
