$lang[‘key’] = ‘val’;

Loading Language file

Before using any type of language in your application, first, you load the file of that particular language to retrieve various data stored in that file.

$this->lang->load(‘filename’, ‘language’);

filename – It is the name parameter of the file you want to load.

Language – It is the language set where you use.

$autoload [‘ language ‘] = array();

Step by Step Guide How to Add Multi-Language In Codeigniter Dynamic With Example

class Lang_controller extends CI_Controller {
public function index()
//Load form helper
//Get the selected language
$language = $this->input->post(‘language’);
//Choose language file according to selected lanaguage
if($language == “french”)
else if($language == “german”)
//Fetch the message from language file.
$data[‘msg’] = $this->lang->line(‘msg’);
$data[‘language’] = $language;
//Load the view file

Add a visual file with name lang_view.php and store in this location application folder /views folder /lang_view.php file

This code add in HTML tags

echo form_open(‘/lang’);
<select name=”language” onchange=”javascript:this.form.submit();”>
$lang =
foreach($lang as $key=>$val)
if($key == $language)
echo “<option value=’”.$key.”‘
echo “<option value=’”.$key.”‘>”.$val.”</option>”;
echo $msg;

Add folders with name English in application folder/language folder.

$lang[‘msg’] = “Test Language.”;
