Saving data to server

I have used shared objects to have the user save local data, but now i need to save many different users data to the server. What would be the best approach? I have tried looking into MySQL, and though the great tuts on this site makes great sence on how to retrieve data from a database, i can not find any info on saving user data from flash into the databases.

My idea right now is to make a login that uses the MySQL database like in the tutorial on this site. But i need to save data from within flash, (just like I’ve done untill now with shared objects) but now on the server side.

Hope any one can help me
Thank you
