所以我设法解决了这个问题。这个googl_shortlink 上面的函数现在如下所示：

function googl_shortlink($url, $post_id = false) {
    global $post;
    if (!$post_id && $post) $post_id = $post->ID;
    elseif ($post_id) $post = get_post($post_id);
    // list all the active languages in an array 
    $enabled_languages = get_option(\'qtranslate_enabled_languages\');

    if (is_404())
        return;

    if ($post && $post->post_status != \'publish\')
        return "";

    // go through each active language, get the properly formatted permalink,
    // shorten it with goo.gl, then add it as a post_meta
    foreach ($enabled_languages as $lid=>$lang) {
        if ((is_singular() || $post) && !is_front_page() && qtrans_isAvailableIn($post_id,$lang)) {
            $shortlink = get_post_meta($post_id, \'_googl_\'.$lang.\'_shortlink\', true);
            if ($shortlink)
                return $shortlink;

            // the last parameter here was the major headache. It\'s called $forceadmin and defaults
            // to false (by default it doesn\'t prepend language-specific path to links generate in /wp-admin)
            $permalink = qtrans_convertURL(get_permalink($post_id),$lang,true);
            $shortlink = googl_shorten($permalink); // shorten the url. No changes done here

            if ($shortlink !== $url) {
                add_post_meta($post_id, \'_googl_\'.$lang.\'_shortlink\', $shortlink, true);
            } else {
                add_post_meta($post_id, \'_googl_\'.$lang.\'_shortlink\', $url, true);
            }
        }
    }
}

保存时触发：

function googl_save_post($post_ID, $post) {
    // Don\'t act on auto drafts.
    if ($post->post_status == \'auto-draft\')
        return;
    $enabled_languages = get_option(\'qtranslate_enabled_languages\');
    foreach ($enabled_languages as $lid=>$lang)
        delete_post_meta($post_ID, \'_googl_\'.$lang.\'_shortlink\');
}
add_action(\'save_post\', \'googl_save_post\', 10, 2);

并显示在仪表板中：

function googl_post_columns($columns) {
    $columns[\'shortlink\'] = \'Shortlink\';
    return $columns;    
}

function googl_custom_columns($column) {
    global $post;

    if (\'shortlink\' == $column) {
        $enabled_languages = get_option(\'qtranslate_enabled_languages\');
        foreach ($enabled_languages as $lid=>$lang) {
            if (qtrans_isAvailableIn($post->ID,$lang)) {
                $shorturl = get_post_meta($post->ID, \'_googl_\'.$lang.\'_shortlink\', true);
                $shorturl_caption = str_replace(\'http://\', \'\', $shorturl);
                $shorturl_info = str_replace(\'goo.gl/\', \'goo.gl/info/\', $shorturl);
                echo "$lang: <a href=\'{$shorturl}\'>{$shorturl_caption}</a> (<a href=\'{$shorturl_info}\'>info</a>)<br />";
            }
        }
    }
}
add_action(\'manage_posts_custom_column\', \'googl_custom_columns\');
add_filter(\'manage_edit-post_columns\', \'googl_post_columns\');

缺点我无法wp_get_shortlink() 使用新的短链接架构。以上googl_shortlink 不返回任何内容，因为这将使foreach循环在处理第一语言后退出。快速更换（可轻松包装在功能中，使其更加友好）：

// can be used anywhere in the loop to get the 
// shortlink for a specific post and language
get_post_meta($post->ID, \'_googl_\'.qtrans_getLanguage().\'_shortlink\', true);

同样的道理也适用于wp_shortlink_wp_head() （因为它调用wp\\u get\\u shortlink）：

function googl_shortlink_wp_head() {
    global $post;
    $shortlink = get_post_meta($post->ID, \'_googl_\'.qtrans_getLanguage().\'_shortlink\', true);

    if (empty($shortlink))
        return;

    echo "<link rel=\'shortlink\' href=\'".esc_url($shortlink)."\' />\\n";
}
// out with the old, in with the new
remove_action(\'wp_head\',\'wp_shortlink_wp_head\',10,0);
add_action(\'wp_head\',\'googl_shortlink_wp_head\',10,0);
