Question

How can I get iso code language in WordPress?
This function :

get_bloginfo('language');

return me the languge like this : en-EN

I create a function like this :

<?php
function pr_language() {
    $lang = get_bloginfo('language');
    $pos = stripos($lang, '-');
    $lang = substr(get_bloginfo('language'),0,-($pos+1));    // retourne "f"
    return $lang;
}
?>  

Is it correct? I want to display en not en-EN

Answer 1

I hope I understood your question. It seems like all you want to display is en-US.

According to WordPress,

Usage:
<?php bloginfo( $show ); ?>

Parameters:
language

So,

EXACT CODE:
<?php bloginfo('language'); ?>

Will output:

en-US

To show only en, just display first two characters.

function show_short_language() {

    <?php echo substr( get_bloginfo ( 'language' ), 0, 2 );?>

}

Just a note for anyone in the future:

<?php echo substr( get_bloginfo ( 'language' ), 0, 2 );?>

Produced:

en

and

<?php echo substr( bloginfo ( 'language' ), 0, 2 );?>

Produced:

en-US
