Is it possible to display
<!-- plugin version 123 (Fr) -->
if the
language is French?
Yes, it is possible and you can use get_bloginfo( 'language' )
which returns a language tag like en-US
for English (US)
.
So if you just want to retrieve the first 2-or-3 character code (e.g. en
for en-US
and en-UK
) of the language tag, you can do:
list ( $lang ) = explode( '-', get_bloginfo( 'language' ) );
echo '<!-- plugin version 123 (' . ucfirst( $lang ) . ') -->';
