If the CSS files of the language switcher are loading from an old URL after moving the website follow the steps below:
The same thing is available via wp-cli command below:
wp wpml clear-cache
The command above is available in WPML 4.4.11 and above.
“Links to the translation of posts” only works for a single post. Some clients asking to add links to translations on blog or archive page for each post.
I encountered two clients so far so I am sharing the script that I am using.
Please add this code in functinos.php file
function wpml_post_languages_in_loop() {
$post_trid = apply_filters('wpml_element_trid', NULL, get_the_ID(), 'post_' . get_post_type());
if (empty($post_trid)){
return;
}
$active_langs = apply_filters( 'wpml_active_languages', NULL, 'skip_missing=0' );
$translations = apply_filters('wpml_get_element_translations', NULL, $post_trid, 'post_' . get_post_type());
if (is_array($translations) && !empty($translations)) {
$langs = array();
foreach ($translations as $translation) {
if (is_object($translation) && isset($active_langs[$translation->language_code]) && $translation->element_id != get_the_ID()) {
$langs[] = 'url-to-image';
}
}
if (!empty($langs)) {
echo __('This post is also available in', 'wpml') . ': ' . implode(' ', $langs);
}
}
}
Then use this function in the template file to display posts links.
wpml_post_languages_in_loop();
Inline (horizontal) custom language selector with different options such as Flags only, Code only, Flags + Code with divisor.
Take the time to study the code.
To use call wpml_custom_language_selector(); in a template
function wpml_custom_language_selector(){
// check if wpml is installed
if (function_exists('icl_get_languages')) {
// get active languages. Available params here:
// http://wpml.org/documentation/getting-started-guide/language-setup/custom-language-switcher/
$languages = icl_get_languages('skip_missing=0&orderby=code&order=desc');
if(!empty($languages)){
echo '<div class="lang_selector">';
foreach($languages as $l){
// from this point on, uncomment whatever output you like
// flags only - do not display current language
/* if(!$l['active']){
echo '<a href="'.$l['url'].'">
<img src="'.$l['country_flag_url'].'" alt="'.$l['language_code'].'" />
</a>';
} */
// the output code options below will display the current language
// this adds an "active" class to the current language anchor
$class = $l['active'] ? ' class="active"' : NULL;
// code only
/*$langs .= '<a ' . $class . ' href="'.$l['url'].'">' . strtoupper ($l['language_code']). '</a> | ';*/
//flag-code divided by a |
/*$langs .= '<a ' . $class . ' href="' . $l['url'] . '"><img src="' . $l['country_flag_url'] . '" alt="' . $l['language_code'] . '" />' . strtoupper ($l['language_code']). '</a> | ';*/
}
// strip the empty space and | from last language
$langs = substr($langs,0,-3);
echo $langs;
echo '</div>';
}
}
}
