How I build User Registration and Form Validation Using CodeIgniter

The following is an important note in building a User Registration and Form Validation Using CodeIgniter.

routes.php

There are two lines that were change/added as follows:

autoload.php

On line 55 we have added database and session to load automatically. This means that you do not need to call it in your controller. $autoload['libraries'] = array('database','session');

config.php

There were only two lines of code that were changed here. At line 17: $config['base_url'] = 'http://localhost/CI/'; At line 227: $config['encryption_key'] = '0rGBISBT61k7453Ooq6343KjtGe9Xjv4'; To generate a random key of your own please visit Random Keygen.

database.php

The last configuration is the database. Don’t forget to change the following as follows: Then we have added the following files according to the folder it belongs: controller/register.php helpers/registration_helper.php models/register_model.php views/register.php views/success.php Take note that you do not need to touch any code that is not under the application’s folder. That is, don’t modify any file under system’s folder. CodeIgniter is a PHP framework and is maintained by the developer. Any modification to the system’s folder will be overwritten if you forgot to backup it when you upgrade to the latest version.
