Database Interaction with Codeigniter 1.7

by Adam Griffiths | April 2010 | Open Source PHP Web Development

Having seen form validation in the previous article, we will now cover database interaction. Databases are the backbone behind any Web application. Without a database, you'd have nowhere to hold all of your data, and SQL queries can become long and cumbersome to type out. Thankfully, CodeIgniter gives us a brilliantly simple way to interact with our Database. The database library also makes changing between database types—from MySQL to Oracle, for example—easier, because it acts as a wrapper and provides many functions for us to use on the database.

In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, you will:

  • Perform database queries with the database library
  • Return query results using the database helper functions
  • Create queries using the active record library
  • Learn how to cache active record queries
  • Modify database tables using database forge

  • Learn how the form validation process works
  • Build a contact form
  • Apply validation rules to the form's input fields
