WebReference.com has posted part four (the final installment) of their "Building a Weblog" series today, focusing on creating the categories for the posts, adding a new entry, and updating a current one.
First off is the creation of the categories script - just a simple little page that takes in the category name (from a form) and inserts it into the categories table in the database. The next form functions in basically the same way, but handles more information. It lets you write and save a new blog entry to the database.
Finally, since everyone makes mistakes, they include a sample script to let you update one of your already posted blog entries, using the same kind of form you used to enter it.
