Hi,

Thank you for the updates and waiting for the details.

Now we have only one tutorial about REST API in our documentation. But it is about using WordPress REST API with WooCommerce Multilingual.

https://wpml.org/documentation/related-projects/woocommerce-multilingual/using-wordpress-rest-api-woocommerce-multilingual/

For your kind information, with WPML you can use the WordPress Rest API as usual. If WPML is installed the only thing it should do is to return an extra field with the language of the post. WPML will save the language when creating a new post(language parameter) and also return a list of languages.

Hi,

You can read a single post via REST API easily by using the ID. For example like this --
hidden link. But the result will be missing the language information. You can add language information to the result by using *rest_prepare_this-post_type* hook. Please check the following tutorial link and sample code for more details. You can place this code in the functions.php of your theme.

https://developer.wordpress.org/reference/hooks/rest_prepare_this-post_type/

add_filter( 'rest_prepare_post', 'filter_post_json', 10, 3 );
add_filter( 'rest_prepare_page', 'filter_post_json', 10, 3 );

function filter_post_json( $data, $post, $context ) {
    $args = array('element_id' => $post->ID, 'element_type' => $post->post_type );
    $lang = apply_filters( 'wpml_element_language_code', null, $args );
    if( $lang ) {
       $data->data['lang'] = $lang;
    }
    return $data;
}

You have to use the REST API exactly the same as without WPML to get translations of any custom fields of a theme options page. The only difference is that you will have a different Rest URL for each language.

For example, if you want to get the latest posts in the default language, you can use:

hidden link

On the other hand, if you want the latest Spanish posts you can use the Spanish URL:

hidden link

Right now we don't have much documentation about the WPML and REST API integrations. But we are planning to add it in future. As you can see, there is nothing special WPML has to do the REST API is provided by WordPress and you just use one URL or another depending on the language you want.

https://developer.wordpress.org/rest-api/

You can use https://wpml.org/wpml-hook/wpml_translate_single_string/ or https://wpml.org/wpml-hook/wpml_translate_string/ API to get the translated Strings.

Please explain more about the following for a better understanding.

How can we add some string translation inside wpml interface without a php wordpress theme ?

Hi,

Thank you for the updates. Hope you can achieve this using *get_next_post* & *get_previous_post* WordPress functions.

Please check the following tutorials and sample code for more details.

https://codex.wordpress.org/Function_Reference/get_next_post

https://codex.wordpress.org/Function_Reference/get_previous_post

add_filter( 'rest_prepare_post', 'filter_posts_next_previous', 10, 3 );

function filter_posts_next_previous( $data, $post, $context ) {
   
    if( get_previous_post() ) {
       $data->data['previous_post'] = get_previous_post();
    }
	
    if( get_next_post() ) {
       $data->data['next_post'] = get_next_post();
    }
	
    return $data;
}
