I have a WordPress template that contains the following element:
<html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes('xhtml'); ?>>
This returns:
<html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en-US" xml:lang="en-US">
Unfortunately the “lang” attribute is invalid XHTML 1.1 – and the client would like this level of validation.
WordPress’ general-template.php file contains the following code:
if ( get_option('html_type') == 'text/html' || $doctype == 'html' )
$attributes[] = "lang="$lang"";
$doctype
is the parameter passed to it (in this case ‘xhtml’). Should get_option
be returning a value other than ‘text/html’? If so, what should I be setting in WordPress to achieve this – if anything?
I’ve also tried using preg_replace to take out the “lang” attribute, but this didn’t seem to be able to match the text. If I enter the text manually, it matches! Possibly an encoding issue with the string being returned by language_attributes?
I solved this. There’s a “language_attributes” filter, so I wrote a plugin that hooks into that and does a simple preg_replace. The replace worked when performed here, and it’s a pretty neat way to handle it.
EDIT
As requested, here’s the code I used:
If this is just a theme on your own site, you could edit header.php and change the
<html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes('xhtml'); ?>>
line to be hardcoded, improves performance too 🙂
