first of all I am brand new to web design. I want to let users add posts that are linked to a location. For the location they enter an address (And I receive the coordinates as described in this video https://www.youtube.com/watch?v=6Pd-zuRWKhQ). I do not know how to start and store the coordinates in the database as all I can do is use the graphical dataset widget to store the user input.
Also later on I need to query the entries by distance to the user but i assume some math in the query algorithm will do.
Please help me I really could not find anything on the net understandable to me.
