How to add a class to the <body> declaration

I am creating multilingual sites and want to change styles based on what language a page is displayed in. Many browsers allow you to define styles that only apply to the specified language, eg. #page-top:lang(en). However IE7 and earlier and all versions of Safari ignore the lang declaration. So instead I would like to add a language specifier as a style in the body declaration. For example

<body class="wordpress ..... lang-en"

I have found the part of header.php that I need to modify in my child theme, inserting PHP code that extracts the language from my page/post, thanks to the WPML multilingual plugin.

<body class="<?php thematic_body_class() ?> lang-<?php echo ICL_LANGUAGE_CODE?>">

However I suspect that header.php is likely to change in future versions of Thematic, so would like to find a way of using a hook, filter or something upgrade safe that would allow me to make this addition to the body.

Any suggestions, please?

Hi,

you can filter body_class. The following code will take the array used to build the body class, add your code and send it back:
```
function extend_body_class($c) {
	$c[] = 'lang-' . ICL_LANGUAGE_CODE;
	return $c;
}
add_filter('body_class', 'extend_body_class');
```

Hi Chris
or anybody =)

Is this filter working yet?
It doesn't work for me.

I'm using WP 3.1 , WPML 2.1.1 and Thematic 0.9.7.8 rev.762

"ICL_LANGUAGE_CODE" is still on the WPML API:

Thank you!

I can confirm that it's working perfectly for me.

This morning I've been working on a new site with the latest versions of Wordpress and the latest, paid-for version of WPML. I cut and pasted Chris's code into my child theme's functions.php and it worked right away.

So a definite YES and belated thanks to Chris for this perfect answer.

Got it!
It didn't work for me, but it works now since I filtered "thematic_body_class" instead of "body_class".
```
function extend_body_class($c) {
	$c[] = 'lang-' . ICL_LANGUAGE_CODE;
	return $c;
}
add_filter('thematic_body_class', 'extend_body_class');
```
Thank you!!!
