Examples

How to use get_language_attributes function in the HTML tag

The most common usage of the get_language_attributes function is to add language attributes to the HTML tag of your WordPress site. This helps to specify the language of the content and optionally the text direction.

<!DOCTYPE html>
<html <?php language_attributes(); ?>>
 <head>
 <meta charset="<?php bloginfo( 'charset' ); ?>">
 <title>My WordPress Site</title>
 </head>
 <body>
 <!-- Your content here -->
 </body>
</html>

How to use get_language_attributes function to set a specific language

You can also use the get_language_attributes function to set a specific language for your WordPress site. Here’s an example of how to do it:

<!DOCTYPE html>
<html <?php echo get_language_attributes( 'en-US' ); ?>>
 <head>
 <meta charset="<?php bloginfo( 'charset' ); ?>">
 <title>My WordPress Site</title>
 </head>
 <body>
 <!-- Your content here -->
 </body>
</html>

How to use get_language_attributes function within an if statement

The get_language_attributes function can also be used within an if statement to change the language attributes based on certain conditions. Here’s an example:

<!DOCTYPE html>
<html 
 <?php 
 if ( is_rtl() ) {
 echo get_language_attributes( 'ar' );
 } else {
 echo get_language_attributes( 'en-US' );
 }
 ?>
>
 <head>
 <meta charset="<?php bloginfo( 'charset' ); ?>">
 <title>My WordPress Site</title>
 </head>
 <body>
 <!-- Your content here -->
 </body>
</html>

This code checks if the text direction is right-to-left (RTL). If it is, the language attributes are set to Arabic (‘ar’). If not, they are set to English (‘en-US’).
