Read from database, populate it into a form and give the user option to edit and save

Hi! I had a project here on GFA earlier: [login to view URL] I want to give the user ability to search after an entry in the database. Populate it in the form, and let the user change the values in the boxes, drop down boxes and checkboxes. And then save it to the database again. This will be done under Joomla, and wrapper. I have the code to extract the username, so the user can only search and edit their own entries in the database. So that aint a problem... Ask if something is unclear.
