Frequently Asked Questions

Common questions about Sublanguage

In menu click on Languages, remove all language custom posts and empty trash. Deleting a language will permanently delete all translations associated to this language. Deleting main language will not delete original posts.

Add this function in your template file

Add this in your function.php file and customize it: add_action('sublanguage_custom_switch', 'my_custom_switch', 10, 2); /** * @param array of WP_Post language custom post * @param Sublanguage_site $this The Sublanguage instance. */ function my_custom_switch($languages, $sublanguage) { ?> <ul> <?php foreach ($languages as $language) { ?> <li class="<?php echo $language->post_name; ?> <?php if ($sublanguage->current_language->ID == $language->ID) echo 'current'; ?>"> <a href="<?php echo $sublanguage->get_translation_link($language); ?>"><?php echo $language->post_title; ?></a> </li> <?php } ?> </ul> <?php }

If you are using menus and you want the language switch into a menu, go to Display > Menu, open option drawer and verify 'language' is selected. Then add as much 'language item' as you have languages. You can even distribute languages on different hierarchy level. If you need current language to be on the first level and further language on the second, you will also want to check current language first in Settings -> Sublanguage Post title, content or excerpt does not translate as expected in my theme First go to Sublanguage>Settings and verify the relevant post type is set to be translatable. Then verify you are using the proper filters in you template file. For echoing post title, you need to ensure ´the_title´ filter is called. // echoing post title inside the loop the_title(); // echoing post title outside the loop echo get_the_title($some_post->ID); // but... echo $post->post_title; // -> Does not translate For echoing post content, you need to ensure ´the_content´ filter is called. // echoing content inside the loop the_content(); // or... echo apply_filters('the_content', get_the_content()); // but... echo $post->post_content; // -> Does not translate echo get_the_content(); // -> Does not translate // echoing post content outside the loop: echo apply_filters('sublanguage_translate_post_field', $some_post->post_content, $some_post, 'post_content'); Same for Excerpts. Permalinks are automatically translated, inside or outside the loop: // echoing permalink echo get_permalink($post->ID); Some texts in my theme do not translate as expected, like 'Comment', 'Leave a Reply', etc. In your template files, verify texts are properly localized, and language packages are properly installed.

Use the global $sublanguage, like this: global $sublanguage; echo $sublanguage->current_language // -> WP_Post object echo $sublanguage->current_language->post_title; // -> Français echo $sublanguage->current_language->post_name; // -> fr echo $sublanguage->current_language->post_content; // -> fr_FR Alternatively you can use a sublanguage filter to call a user function with $current_language value in parameters: Function to use in your template file: echo apply_filters('sublanguage_custom_translate', 'text to translate', 'my_custom_translation', 'optional value'); Code to add in your function.php file: /** * @param string $original_text. Original text to translate. * @param WP_Post object $current_language * @param mixed $args. Optional arguments */ function my_custom_translation($original_text, $current_language, $optional_arg) { if ($current_language->post_name == 'fr') { return 'texte traduit en français!'; } return $original_text; } Note: of course, for a basic usage like this, you should use the standard localization way: __('text to translate', 'my_domain').

Go to Sublanguage>Translate Options and try to find the corresponding option key. Options may be nested in a data tree.

Go to Sublanguage>Translate Options and find the corresponding widget option name (like 'widget_somthing'). Expand items with value corresponding to 'DATA' until you find the text you need to translate.

Your nav menu items that are linked to translated posts, pages or terms should be automatically translated. If you need to translate custom link or to change the default value for items name, you can select "Nav Menu Item" in "Translate post types" section of Sublanguage settings. Then open Sublanguage>Nav Menu Item and edit like a normal post.

Go to Sublanguage settings and select custom post-meta key in the checkbox list under "Translate Meta". A meta key needs to be at least used once to appear in this list.

Go to Sublanguage settings and select '_thumbnail_id' in the checkbox list under "Translate Meta". At least one thumbnail must be set before metakey appears in this list.
