So lately I've been trying to set up a small plugin. It's a birthdaylist. In my file I've set up a database and a submenu page where I'm able to add new birthdays. Then there's a function to show all the birthdays in a list on the frontend.
That works well so far.
Now I want to show the names on the option page and put a link next to it to delete this row from the database. I've tried some things with the GET method and with setting up an extra side. But I never was quite sure what content I have to put into my plugin to make it work.
I've uploaded the content of the plugin as text:
It would be wonderful if somebody could tell me how to deal with that or if somebody could show me a really good tutorial on it.
