In this chapter, we have learned an important lesson, which is that by utilizing built-in WordPress functionalities whenever we can, we are able to save both time and effort. And our shared plugin functionality will automatically follow the development of WordPress.
The Ajax Wall widget allows you to post quick comments. The comments will of course need to pass all internal verifications of WordPress before they can appear on our page. And we can easily manage comments from the WordPress administration interface.
We have covered important areas of WordPress development:
Widgets: Creating and managing widgets on our blog
Options: Using WordPress to manage our plugin options easily
Database: Working with WordPress database to insert and retrieve information
Ajax forms: Submitting forms and get the results without reloading the page
In the next chapter, we are going to look over more WordPress features and development techniques by developing a super cool Snazzy Archives plugin.
