In this chapter we will begin to build the blogging functionality for our Web application. We will implement the tools that will permit each user to create and manage their own blog posts. In this chapter we will be adding the following functionality to our web application Enable users to create new blog posts. A blog post will consist of a title the date submitted and the content text or HTML relating to the post. We will implement the form and corresponding processing code that allows users to enter this content and that correctly filters submitted HTML code so JavaScript-based attacks cannot occur. This form will also be used for editing existing posts. Permit users to preview new posts. This simple workflow system will allow users to double-check a post before sending it live. When a user creates a new post they will have an option to either preview the post or send it live immediately. When previewing a post they will have the option to either send it live or to make further changes. Notify users of results. We will implement a system that notifies the user what has happened when they perform an action. For instance when they choose to publish one of their blog posts the notification system will flash a message on the screen confirming this action once it has happened. There are additional features we will be implementing later in this book such as tags images and web feeds in this chapter we will simply lay the groundwork for the blog. There will be some repetition of Chapter 3 in this chapter when we set up database tables and classes for modifying the database but I will keep it as brief as possible and point out the important differences. Because there is a lot of code to absorb in developing the blog management tools Chapter 8 .
