I have a sql database of historical events, I would like it to post data into the sidebar area of a wordpress site. As I am very new to it I do not have any idea how to proceed. I would be thankful if anyone could help me out. Thanks in advance
You can edit the
sidebar.php (or any
sidebar-xxx.php file, depends on your theme) and interface with your database using the wpdb class.
If your historical events are in the same DB as wordpress you can use the wpdb class straight away, if they are in another DB you can instanciate a new wpdb class with :
$my_db = new wpdb('user','pass','dbname','host');
