These translations or additional messages would go inside -your **application/language/** directory, with separate sub-directories for each idiom -(for instance, 'french' or 'german'). - -The CodeIgniter framework comes with a set of language files for the "english" idiom. -Additional approved translations for different idioms may be found in the -`CodeIgniter 3 Translations repositories <https://github.com/bcit-ci/codeigniter3-translations>`_. -Each repository deals with a single idiom. - -When CodeIgniter loads language files, it will load the one in **system/language/** -first and will then look for an override in your **application/language/** directory. - -.. note:: Each language should be stored in its own folder. For example, - the English files are located at: system/language/english - -.. contents:: - :local: - -.. raw:: html - - <div class="custom-index container"></div> - -*************************** -Handling Multiple Languages -*************************** - -If you want to support multiple languages in your application, you would provide folders inside -your **application/language/** directory for each of them, and you would specify the default -language in your **application/config/config.php**. - -The **application/language/english/** directory would contain any additional language files -needed by your application, for instance for error messages. - -Each of the other idiom-specific directories would contain the core language files that you -obtained from the translations repositories, or that you translated yourself, as well as -any additional ones needed by your application. - -You would store the language you are currently using, for instance in a session variable. - -Sample Language Files -===================== - -:: - - system/ - language/ - english/ - ... - email_lang.php - form_validation_lang.php - ... - - application/ - language/ - english/ - error_messages_lang.php - french/ - ... - email_lang.php - error_messages_lang.php - form_validation_lang.php - ... - -Example of switching languages -============================== - -:: - - $idiom = $this->session->get_userdata('language'); - $this->lang->load('error_messages', $idiom); - $oops = $this->lang->line('message_key'); - -******************** -Internationalization -******************** - -The Language class in CodeIgniter is meant to provide an easy and lightweight -way to support multiplelanguages in your application. It is not meant to be a -full implementation of what is commonly called `internationalization and localization -<http://en.wikipedia.org/wiki/Internationalization_and_localization>`_. - -We use the term "idiom" to refer to a language using its common name, -rather than using any of the international standards, such as "en", "en-US", -or "en-CA-x-ca" for English and some of its variants. - -.. note:: There is nothing to prevent you from using those abbreviations in your application! - -************************ -Using the Language Class -************************ - -Creating Language Files -======================= - -Language files must be named with **_lang.php** as the filename extension. -For example, let's say you want to create a file containing error messages. -You might name it: error_lang.php - -Within the file you will assign each line of text to an array called -``$lang`` with this prototype:: - - $lang['language_key'] = 'The actual message to be shown'; - -.. note:: It's a good practice to 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 to 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 to 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. - -You can also load multiple language files at the same time by passing an array of language files as first parameter. -:: - - $this->lang->load(array('filename1', 'filename2')); - -.. note:: The *language* parameter can only consist of letters. - -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 to the line you wish -to show. - -You can optionally pass FALSE as the second argument of that method to -disable error logging, in case you're not sure if the line exists:: - - $this->lang->line('misc_key', FALSE); - -.. note:: This method simply returns the line. It does not echo it. - -Using language lines as form labels ------------------------------------ - -This feature has been deprecated from the language library and moved to -the :php:func:`lang()` function of the :doc:`Language Helper -<../helpers/language_helper>`. - -Auto-loading Languages -====================== - -If you find that you need a particular language globally throughout your -application, you can tell CodeIgniter to :doc:`auto-load -<../general/autoloader>` it during system initialization. This is done -by opening the **application/config/autoload.php** file and adding the -language(s) to the autoload array. - -*************** -Class Reference -*************** - -.. php:class:: CI_Lang - - .. php:method:: load($langfile[, $idiom = ''[, $return = FALSE[, $add_suffix = TRUE[, $alt_path = '']]]]) - - :param mixed $langfile: Language file to load or array with multiple files - :param string $idiom: Language name (i.e. 'english') - :param bool $return: Whether to return the loaded array of translations - :param bool $add_suffix: Whether to add the '_lang' suffix to the language file name - :param string $alt_path: An alternative path to look in for the language file - :returns: Array of language lines if $return is set to TRUE, otherwise void - :rtype: mixed - - Loads a language file. - - .. php:method:: line($line[, $log_errors = TRUE]) - - :param string $line: Language line key name - :param bool $log_errors: Whether to log an error if the line isn't found - :returns: Language line string or FALSE on failure - :rtype: string - - Fetches a single translation line from the already loaded language files, - based on the line's name.
