CodeIgniter Tutorial for Beginners<\/a> first.<\/p>\nSite Default Language<\/h2>\n
Open the application\/config\/config.php<\/code> file and specify the site’s default language.<\/p>\n$config<\/span>[<\/span>'language'<\/span>] = <\/span>'english'<\/span>;<\/span><\/pre>\nCreating Language Files<\/h2>\n
Create multiple language files and insert those files into the application\/language\/<\/code> directory with separate sub-directories for each language (for example, french, german, etc.).<\/p>\nThe language files must be named with _lang<\/code> suffix. For example, if you want to create a file containing site’s message translation then the file name might be message_lang.php<\/code>.<\/p>\nLanguage files structure would look like following.<\/p>\n
\n- application\/<\/b>\n
\n- language\/<\/b>\n
\n- english\/<\/b>\n
\n- message_lang.php<\/li>\n
- ……<\/li>\n<\/ul>\n<\/li>\n
- french\/<\/b>\n
\n- message_lang.php<\/li>\n
- ……<\/li>\n<\/ul>\n<\/li>\n
- german\/<\/b>\n
\n- message_lang.php<\/li>\n
- ……<\/li>\n<\/ul>\n<\/li>\n
- ……<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Within the language file (message_lang.php<\/code>) you would need to assign each line of text to $lang<\/code> array. <\/p>\n$lang<\/span>[<\/span>'language_key'<\/span>] = <\/span>'The actual message to be shown'<\/span>;<\/span><\/pre>\nSample language files are given below.<\/p>\n
\n- \n
english\/message_lang.php<\/code> file would be look like the following.<\/p>\n<?php
$lang<\/span>[<\/span>'welcome_message'<\/span>] = <\/span>'Welcome to CodexWorld'<\/span>;<\/span><\/span><\/pre>\n<\/li>\n- \n
french\/message_lang.php<\/code> file would be look like the following.<\/p>\n<?php
$lang<\/span>[<\/span>'welcome_message'<\/span>] = <\/span>'Bienvenue \u00e0 CodexWorld'<\/span>;<\/span><\/span><\/pre>\n<\/li>\n- \n
german\/message_lang.php<\/code> file would be look like the following.<\/p>\n<?php
$lang<\/span>[<\/span>'welcome_message'<\/span>] = <\/span>'Willkommen in CodexWorld'<\/span>;<\/span><\/span><\/pre>\n<\/li>\n<\/ul>\nLoading Language Files<\/h2>\n
In order to fetch a line from a particular language file, you need to load the language file first. There are two options for loading a language file.<\/p>\n
In Controller:<\/b>
\nInto the controller’s __construct()<\/code> function write the following code.<\/p>\n$this<\/span>-><\/span>lang<\/span>-><\/span>load<\/span>(<\/span>'message'<\/span>,<\/span>'english'<\/span>);<\/span><\/pre>\nIf you choose this option, you need to load language file in all controller of your application.<\/p>\n
Using Hooks:<\/b>
\nFor using the hooks option you need to enable the hooks feature in application\/config\/config.php<\/code> file.<\/p>\n$config<\/span>[<\/span>'enable_hooks'<\/span>] = <\/span>TRUE<\/span>;<\/span><\/pre>\nOpen application\/config\/hooks.php<\/code> file and define a hook.<\/p>\n$hook<\/span>[<\/span>'post_controller_constructor'<\/span>] = array(
<\/span>'class' <\/span>=> <\/span>'LanguageLoader'<\/span>,
<\/span>'function' <\/span>=> <\/span>'initialize'<\/span>,
<\/span>'filename' <\/span>=> <\/span>'LanguageLoader.php'<\/span>,
<\/span>'filepath' <\/span>=> <\/span>'hooks'
<\/span>);<\/span><\/pre>\nCreate LanguageLoader class in LanguageLoader.php<\/code> file inside the application\/hooks\/<\/code> directory. LanguageLoader.php<\/code> file contain the following code.<\/p>\n<?php
<\/span>class <\/span>LanguageLoader
<\/span>{
function <\/span>initialize<\/span>() {
<\/span>$ci <\/span>=& <\/span>get_instance<\/span>();
<\/span>$ci<\/span>-><\/span>load<\/span>-><\/span>helper<\/span>(<\/span>'language'<\/span>);
<\/span>$ci<\/span>-><\/span>lang<\/span>-><\/span>load<\/span>(<\/span>'message'<\/span>,<\/span>'english'<\/span>);
}
}<\/span><\/span><\/pre>\nFetching line of text<\/h2>\n
After loading the language file you can fetch the line text using the following code.<\/p>\n
$this<\/span>-><\/span>lang<\/span>-><\/span>line<\/span>(<\/span>'welcome_message'<\/span>);<\/span><\/pre>\nSwitch Different Languages<\/h2>\n
Now it’s time to switch different languages and make your site multilingual. We will use the session to store user’s requested language and load the respective language.<\/p>\n
Before starting to implement multilingual features, open the application\/config\/autoload.php<\/code> file and load SESSION<\/b> library and URL<\/b> helper.<\/p>\n$autoload<\/span>[<\/span>'libraries'<\/span>] = array(<\/span>'session'<\/span>);
<\/span>$autoload<\/span>[<\/span>'helper'<\/span>] = array(<\/span>'url'<\/span>);<\/span><\/pre>\nWe will create LanguageSwitcher controller for handing the language switch. application\/controllers\/LanguageSwitcher.php<\/code> file contain the following code.<\/p>\n<?php <\/span>if ( ! <\/span>defined<\/span>(<\/span>'BASEPATH'<\/span>)) exit(<\/span>'No direct script access allowed'<\/span>);
class <\/span>LanguageSwitcher <\/span>extends <\/span>CI_Controller
<\/span>{
public function <\/span>__construct<\/span>() {
<\/span>parent<\/span>::<\/span>__construct<\/span>();
}
function <\/span>switchLang<\/span>(<\/span>$language <\/span>= <\/span>\"\"<\/span>) {
<\/span>$language <\/span>= (<\/span>$language <\/span>!= <\/span>\"\"<\/span>) ? <\/span>$language <\/span>: <\/span>\"english\"<\/span>;
<\/span>$this<\/span>-><\/span>session<\/span>-><\/span>set_userdata<\/span>(<\/span>'site_lang'<\/span>, <\/span>$language<\/span>);
<\/span>redirect<\/span>(<\/span>$_SERVER<\/span>[<\/span>'HTTP_REFERER'<\/span>]);
}
}<\/span><\/span><\/pre>\nOpen the application\/hooks\/LanguageLoader.php<\/code> file and replace file’s code with the following code.<\/p>\n<?php
<\/span>class <\/span>LanguageLoader
<\/span>{
function <\/span>initialize<\/span>() {
<\/span>$ci <\/span>=& <\/span>get_instance<\/span>();
<\/span>$ci<\/span>-><\/span>load<\/span>-><\/span>
