Problem: We would like to define short links. Suppose we have the primary page "Test DE" with the URL "xyz.tld/test-de". The following translations exist for this page: - "Test EN": xyz.tld/en/test-en - "Test FR": xyz.tld/fr/test-fr - "Test IT": xyz.tld/it/test-it Now we want to define the short link /test, which refers to these pages, where the language of the page should be defined automatically based on the browser language. Solution:
if( !is_admin() ) {
global $sitepress;
$page_id = url_to_postid( $_SERVER['REQUEST_URI'] );
// Determine available translations of the current article
$translation_id = $sitepress->get_element_trid( $page_id );
$translations = $sitepress->get_element_translations( $translation_id );
$supported_lang = array_keys( $translations );
// Set language according to supported browser languages. If there is no match,
// first value of $supported_lang is set as language.
$lang = http_negotiate_language( $supported_lang );
// Overwrite language with value from cookie
$lang_cookie = isset( $_COOKIE[ 'lang' ] ) ? $_COOKIE[ 'lang' ]: '';
if ( in_array( $lang_cookie, $supported_lang ) ) {
$lang = $lang_cookie;
}
// Overwrite language with value from URL parameter "lang"
$lang_url = isset( $_GET[ 'lang' ] ) ? $_GET[ 'lang' ] : '';
if ( in_array( $lang_url, $supported_lang ) ) {
$lang = $lang_url;
}
// If previous language differs from newly defined language, set/adjust cookie and change language
if ( in_array( $lang, $supported_lang ) ) {
if ( $sitepress->get_current_language() != $lang ) {
setcookie ( 'lang', $lang, time() + (10 * 365 * 24 * 60 * 60), '/' );
do_action( 'wpml_switch_language', $lang );
}
}
}
