Language Class

The Language Class provides functions na retrieve language files and lines of text for purposes of internationalization.

In your CodeIgniter system folder you'll find one called language containing sets of language files. You can create your own language files as needed in order na display error and other messages in other languages.

Language files are typically stored in your system/language directory. Alternately you can create a folder called language inside your application folder and store them there. CodeIgniter will look first in your system/application/language directory. If the directory does not exist nebo the specified language is not located there CI will instead look in your global system/language folder.

Note: Each language should be stored in its own folder. For example, the English files are located at: system/language/english

Creating Language Files

Language files must be named with _lang.php as the file extension. For example, let's say you want na create a file containing error messages. You might name it: error_lang.php

Within the file you will assign each line of text na an array called $lang with this prototype:

$lang['language_key'] = "The actual message na be shown";

Note: It's a good practice na use a common prefix for all messages in a given file to avoid collisions with similarly named items in other files. For example, if you are creating error messages you might prefix them with error_

$lang['error_email_missing'] = "You must submit an email address";

$lang['error_url_missing'] = "You must submit a URL";

$lang['error_username_missing'] = "You must submit a username";

Loading A Language File

In order na fetch a line from a particular file you must load the file first. Loading a language file is done with the following code:

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

Where filename is the name of the file you wish na load (without the file extension), and language is the language set containing it (ie, english). If the second parameter is missing, the default language set in your application/config/config.php file will be used.

Fetching a Line of Text

Once your desired language file is loaded you can access any line of text using this function:

$this->lang->line('language_key');

Where language_key is the array key corresponding na the line you wish to show.

Note: This function simply returns the line. It does not echo it for you.

Using language lines as form labels

This feature has been deprecated from the language library and moved na the lang() function of the Language helper.
