CodeIgniter .htaccess and URL Rewriting Issues

Navigating CodeIgniter applications often requires removing "index.php" from the URL, allowing users to access pages with a cleaner syntax. However, new users may encounter difficulties with this process.

The key to removing "index.php" lies in modifying the application config file (application/config.php) and creating a .htaccess file in the root directory.

1. Application Configuration:

In application/config.php, ensure the following settings:

$config['base_url'] = 'http://'.$_SERVER['SERVER_NAME'].'/Your Ci folder_name';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

2. .htaccess File:

Create a .htaccess file in the root directory with the following code:

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

3. Rewrite Engine Enablement:

Ensure the rewrite engine is enabled by:

• Initiating it with "a2enmod rewrite".
• Changing "AllowOverride None" to "AllowOverride All" in /etc/apache2/sites-enabled/000-default or /etc/apache2/apache2.conf.
• Restarting the server with the command "sudo /etc/init.d/apache2 restart".

Additional Notes:

If accessing a page via "localhost/ci/about" fails, consider:

• Using "localhost/ci/index.php/about" or creating an "about" directory in application/.
• Checking for any directives in the .htaccess file that may be interfering.
