I would like to create a site for members of an association. To be associated, you have to pay monthly.
In this site, I wanted that the logged in member could see only his extract of payment (and other specific and private data), from a data-base fullfilled by me (as administrator of the site). The extracts of payments can not be available to other members, because it needs to be a private information.
How is the best way to implement that? What codes or apps do I need?
