I have the following question. I have my bunch of libraries - modules (I can't name that a CMS, even it is look like one, since customer can edit almost all parts of his website), which I use in my everyday projects which are - customer websites.
I live and work in Greece, hence standard webiste here is considered 2 languages, Greek and English. It happens however customer to request 3,4 or more languages. My libraries - modules and database tables are created for 2 languages, and if customer request more than 2 languages, I have to alter all the modules that have to be installed on the customer website.
For example, here is how FAQ Categories table look like:
CREATE TABLE IF NOT EXISTS `faq_categories` (
`catid` int(11) NOT NULL AUTO_INCREMENT,
`parentid` int(11) DEFAULT NULL,
`categoryname` varchar(255) NOT NULL,
`categoryname_en` varchar(255) DEFAULT NULL,
`sorder` int(11) NOT NULL,
`visible` tinyint(4) NOT NULL,
`categoryphoto` varchar(255) DEFAULT '',
PRIMARY KEY (`catid`),
KEY `parentid_fk` (`parentid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=195 ;
Now, as you can imagine, if customer request one more language, I have to alter not only the database tables, but the php code as well, which on large project may be quite cumbersome.
Can anyone propose better database design than this? It would be nice to have somewhere langid field, and the record to be retrieved on base on that, but I have no clear picture of how that may work. Any idea or link for further reading will be deeply appreciated.
I post this question here on database forum because If I create the design of the database right, I will find my way in CodeIgniter (php).
