Reply To: WPML and ACF Options

For this issue, I wrote a little solution to use ACF options to work more easily with WPML

The fields name

First you have to set yours fields name for the option page in default language (or global) like

• my_field

For other language options pages (see ICL_LANGUAGE_CODE code return), set the field like this :

• my_field_fr
• my_field_en

The functions

function get_field_wpml( $field_key, $post_id = false, $format_value = true ) {

    global $sitepress;

    $is_cascade   = $post_id == 'option' && $format_value == true ? true : false;
    $format_value = $post_id == 'option' ? true : $format_value; // force $format_value = true for option

    // get field for default language
    elseif ( ( $sitepress->get_default_language() == ICL_LANGUAGE_CODE ) && ( $ret = get_field( $field_key, $post_id, $format_value ) ) ) {
       return $ret;
    }

    // get field for current language
    if ( $ret = get_field( $field_key . '_' . ICL_LANGUAGE_CODE, $post_id, $format_value ) ) {
        return $ret;
    }

    // get field when if not exists for locale by cascade
    elseif ( $is_cascade ) {
        return get_field( $field_key, $post_id, $format_value );
    }

    return false;
}

function have_rows_wpml( $field_key, $post_id = false ) {

    global $sitepress;

    if ( $sitepress->get_default_language() == ICL_LANGUAGE_CODE ) {
       return have_rows( $field_key, $post_id );
    }

    return have_rows( $field_key . '_' . ICL_LANGUAGE_CODE, $post_id );
}

The second function need to be enhanced to support cascade for quering

Examples of use

1/ To get an option value for the current language, and if not, for the default language (cascade)

$my_field = get_field_wpml( 'my_field', 'option' ); 

2/ To get an option value ONLY for the current language (no cascade) – Set the third parameter to false

$my_field = get_field_wpml( 'my_field', 'option', false ); 

3/ To iterate on repeater or flexible content, use like this :

while ( have_rows_wpml( 'my_repeater_field', 'option' ) ):
    the_row();
    $my_sub_field = get_sub_field('my_sub_field', 'option');
endwhile;
