Codeigniter 2.x – setup after installation

After clean installation of CodeIgniter 2.x framework (e.g. to localhost) I recommend following steps:

1) Setup ‘base_url’ to application

• open /application/config/config.php
• change base_url (e.g. $config[‘base_url’] = ‘http://localhost/mydomain/’;)

2) Give up index.php from URL

• create .htaccess file in to root of the project (e.g. mydomain) + edit RewriteBase /mydomain/
• open /application/config/config.php
• and change index_page to $config[‘index_page’] = ”;

3) Change default controller

• open /application/config/routes.php
• change default_controller (e.g. $route[‘default_controller’] = “itemlist”;)

4) Setup autoload of database

• open /application/config/autoload.php
• change libraries to $autoload[‘libraries’] = array(‘database’);
• open /application/config/database.php
• setup parameters for database (DB) connection

5) Set up form protection

• open /application/config/config.php
• set csrf_protection ($config[‘csrf_protection’] = ‘TRUE’;)

6) Turn on using of sessions
Comment: Relevant only when we need to use user’s registration & login.

• open /application/config/config.php
• set encryption_key (e.g. $config[‘encryption_key’] = ‘SomeEncryptionKey’;)
• if you want to set your sessions to DB then:
  • set sess_use_database ($config[‘sess_use_database’] = ‘TRUE’;)
  • set sess_table_name (e.g. $config[‘sess_table_name’] = ‘ci_sessions’;)
