| <h1>Language Class</h1> | |
| <p>The Language Class provides functions to retrieve language files and lines of text for purposes of internationalization.</p> | |
| <p>In your Code Igniter system folder you'll find one called <dfn>language</dfn> containing sets of language files. You can create | |
| your own language files as needed in order to display error and other messages in other languages.</p> | |
| <h2>Creating Language Files</h2> | |
| <p>Language files must be named with <kbd>_lang.php</kbd> as the file extension. For example, let's say you want to create a file | |
| containing error messages. You might name it: <kbd>error_lang.php</kbd></p> | |
| <p>Within the file you will assign each line of text to an array called <var>$lang</var> with this prototype:</p> | |
| <code>$lang['language_key'] = "The actual message to be shown";</code> | |
| <p><strong>Note:</strong> 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:</p> | |
| <code>$lang['<var>error</var>_email_missing'] = "You must submit an email address";<br /> | |
| $lang['<var>error</var>_url_missing'] = "You must submit a URL";<br /> | |
| $lang['<var>error</var>_username_missing'] = "You must submit a username";</code> | |
| <h2>Loading A Language File</h2> | |
| <p>In order to fetch a line from a particular file you must load the file first. Loading a language file is done with the following code:</p> | |
| <code>$this->lang->load('<samp>filename</samp>', '<dfn>language</dfn>');</code> | |
| <p>Where <samp>filename</samp> is the name of the file you wish to load (without the file extension), and <dfn>language</dfn> | |
| is the language set containing it (ie, english). If the second parameter is missing, the default language set in your | |
| <kbd>application/config/config.php</kbd> file will be used.</p> | |
| <h2>Fetching a Line of Text</h2> | |
| <p>Once your desired language file is loaded you can access any line of text using this function:</p> | |
| <code>$this->lang->line('<samp>language_key</samp>');</code> | |
| <p>Where <samp>language_key</samp> is the array key corresponding to the line you wish to show.</p> | |
| <p>Note: This function simply returns the line. It does not echo it for you.</p> | |
