7.7. Conclusion
In this chapter, you learned how to extend a basic set of administrative screens and add much needed functionality, like batch operations and import/export features. You even made a fairly wide-ranging series of changes involving colors and sizes.
In the next chapter, you'll add even more features to the site, including a Newsletter tool and a simple page manager.
Remember to keep these thoughts in mind as you continue working with CodeIgniter:
If you find yourself in a situation in which you have to rework a big part of your application, don't panic. Make a list of all the changes that need to be made, and then systematically address those issues in your models, database tables, controllers, and views.
Learn the power of such functions as $this->db->insert_id(), which allows you to track newly inserted IDs for any table.
Never hesitate to reuse functionality. If you've written model functions for an admin dashboard, feel free to reuse those same functions on the public side.
