Hey guys I am completely new to wordpress. How can I create a backend plugin, which can show all items from the db table 'phones'. With some buttons to edit, add and remove items. Everything should be a backend module for admins, but with the option to show some phones on the frontend. All I actually need is how to begin, because I never coded something for wordpress and just don’t know how to start with this. Tutorials would be awesome or a plugin which already does this. Sorry for my bad english.
