FlightLog is a WordPress plugin which helps you track your flights, gives a nice summary of them in your sidebar and even plots them on a map.
Log on with Admin privileges and go to Plugins->FlightLog to configure the plugin:
To edit an entry, click its name (hit the "Update" button when ready). Note that this will update all existing records that refer to this entry. If an entry (airport, airline, aircraft) is not used in any flight, there will also be a "Delete" button which you can use to delete the entry (if you need to delete an entry, but it is used, first delete all flights that us it).
From the same page you can manage the measurement units: metric (distances calculated in kilometers) or US (in miles). If you change the measurement units, FlightLog will automatically re-calculate all flights in the new ones.
Log on as Editor and go to Tools->FlightLog. Chose date, airports from and to, airline and aircraft. FlightLog will automatically calculate the distance (based on cached airport coordinates) and flight duration. If you need to correct them, click the number of the flight. From the same screen you can also delete a flight.
FlightLog will auto detect the user that is currently logger in, so the new flight will be recorded on his account (meaning that you have separate log for separate users on your system).
To display the flight summary, add the FlightLog widget to your desired sidebar. It will display total number of flights, distance and time per each user that has flights.
To display a map with the flights, create a new post or page where you want the map displayed and enter tag like this:
where XXX is the username for which you want the map displayed. You can limit the time interval to certain years by also adding
year_to=YYYY in the square brackets after the username. Each route will be shown on the map; click the route to get additional info (departure and destination airports, number of flights on it and details on the last: date, carrier and aircraft).
To link a post or page with a map to the widget (so that the name in the widget becomes a link to the post or page), go to same page where you manage your flights find the "Widget link" section on top; then click "Find" and select the proper post or page. To change the link, use the same procedure. To remove the link, use the "Delete" button next to it.
