Passing Data from Database to Codeigniter Language Files
In your quest to create a multi-lingual website with Codeigniter, you rightly envision using a database to manage language content. This article will guide you through the specific steps to achieve this.
Database Structure and Language Files
Firstly, set up a database table named lang_token to store language tokens. Populate it with columns for id, category, description, lang, and token. For instance, create English tokens like:
| id | category | description | lang | token | |---|---|---|---| | 1 | error | noMail | english | You must submit a valid email address | | 2 | error | noUser | english | You must submit a username |
Next, organize language files in subdirectories within application/language (e.g., application/language/english).
Codeigniter Language Files Structure
Language files follow a specific structure:
$lang['category_description'] = 'token';
For example, in application/language/english/general_lang.php:
$lang['error_noMail'] = 'You must submit a valid email address'; $lang['error_noUser'] = 'You must submit a username';
Controller Function for Dynamic Language File Generation
To create language files dynamically from the database, create a controller function like this:
function updatelangfile($my_lang){ $query = $this->db->where('lang', $my_lang)->get('lang_token'); $langstr = "<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');\n\n\n"; foreach ($query->result() as $row){ $langstr.= "$lang['".$row->category."_".$row->description."'] = \"$row->token\";\n"; } write_file('./application/language/'.$my_lang.'/general_lang.php', $langstr); }
Usage
Whenever you update your database, call the function updatelangfile('english') to regenerate the language file.
