CodeIgniter Session Error – Operation not Permitted

On some hostings you can receive this error.

A PHP Error was encountered

Severity: Warning

Message: unlink(/tmp/ci_session0189a7f1c86eb18fb70afcfedc2d5040e9c23146): Operation not permitted

Filename: drivers/Session_files_driver.php

To fix this go to application > config > config.php and edit this line:

$config['sess_save_path'] =  BASEPATH . 'cache/';

Codeigniter 3 – Fast setup

Download and extract codeigniter. In main folder create another folder named assets. There will be additional files for css, js and more.

Setup configuration files. Go to application/config:
– in autoload.php

$autoload['libraries'] = array('database','session');
$autoload['helper'] = array('url','form');

– in config.php

$config['base_url'] = 'http://www.example.com/';
$config['index_page'] = '';
$config['encryption_key'] = 'someEncryptionKey';
$config['sess_save_path'] = sys_get_temp_dir(); //Fix problems with session

– in database.php

'username' => 'root',
'password' => 'rootPassword',
'database' => 'DatabaseName',

– in routes.php

$route['default_controller'] = 'Main_controller';

Step 2 Create Main_controller file in application/controllers
Easiest way is to copy and rename Welcome.php

Step 3 Create .htaccess file in main folder. This is a must for routing!

RewriteEngine On

RewriteCond %{HTTP_HOST} ^my-domain.com [NC]
RewriteRule ^(.*)$ http://www.my-domain.com/$1 [L,R=301]

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /index\.php(/[^\ ]*)?\ HTTP/
RewriteRule ^index\.php(/(.*))?$ http://www.my-domain.com/$2 [R=301,L]
 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

Multilanguage CodeIgniter 3.0

In this tutorial we will implement multilanguage to CodeIgniter.

Site Default Language
Open the application/config/config.php file and specify the site’s default language.

$config['language']  = 'bulgarian';  //Language you want to be default

Language Files

The language files must be named with _lang suffix. For example, if you want to create a file containing site’s message translation then the file name might be message_lang.php.

Insert those files into the application/language/ directory with separate sub-directories for each language (for example, english, bulgarian, etc.).
