I want to create a custom admin page which contains 3 text-fields. These text fields should have a default text in them. But the admin should be able to edit this and save the customized text. Which should save to the database and be able to be picked up in the front end. I was thinking about doing a custom post type for this. But in custom post types you are able to create multiple posts. And I just want 3 text fields, and 3 database values for this.
Is there any simple way to achieve this? Could not find anything when I searched.
