Wordpress - 注意：使用未定义的常量 Redux_TEXT_DOMAIN - 假定为“Redux_TEXT_DOMAIN”

Question

我正在构建我的第一个 Wordpress 网站，我刚刚下载并安装了 v3.9.1。我买了一个主题（rustik3）并尝试安装它，但我遇到了 WP_DEBUG 产生的这些错误：

Notice: Use of undefined constant Redux_TEXT_DOMAIN - assumed 'Redux_TEXT_DOMAIN' in /var/www/wp-content/themes/rustik3/admin/options.php on line 501

Notice: Use of undefined constant Redux_TEXT_DOMAIN - assumed 'Redux_TEXT_DOMAIN' in /var/www/wp-content/themes/rustik3/admin/options.php on line 502

Notice: Use of undefined constant Redux_TEXT_DOMAIN - assumed 'Redux_TEXT_DOMAIN' in /var/www/wp-content/themes/rustik3/admin/options.php on line 503

Notice: Undefined variable: item_info in /var/www/wp-content/themes/rustik3/admin/theme-functions.php on line 23

我已经做了一些谷歌搜索，我开始认为最后一次 Wordpress 更新使得 Redux 框架已被弃用并且无法使用。不过，这只是一种预感。截至目前，主题已安装，但它显示为完全空白 - 当我转到 http://localhost 或尝试在 Wordpress UI 中自定义它时。我还没有查看错误消息日志的最后一部分（第 23 行错误）......但它只是一个未定义的变量，所以我可以自己解决这个问题。有什么想法吗？

更新

这就是options.php 中的代码块的样子：

array(
            'id' => 'google_webfonts',
            'type' => 'google_webfonts',
            'title' => __('Enable Google Webfonts', Redux_TEXT_DOMAIN), 
            'sub_desc' => __('Pick from over 600 Google Webfonts to use on the site. Then select below which elements you want to apply it to.', Redux_TEXT_DOMAIN),
                'desc' => __('', Redux_TEXT_DOMAIN)
      ),

更新

我对 Redux_TEXT_DOMAIN 的所有 wordpress 文件进行了文本搜索，它出现的唯一位置是在上面的代码块中......

更新

这段代码是在我拥有的主题中加载文本域...我不熟悉文本域是什么 - 但这可能是相关的：

public function load_textdomain() {
        if ( isset( $this->textdomain_loaded ) )
            return $this->textdomain_loaded;

        $textdomain = $this->get('TextDomain');
        if ( ! $textdomain ) {
            $this->textdomain_loaded = false;
            return false;
        }

        if ( is_textdomain_loaded( $textdomain ) ) {
            $this->textdomain_loaded = true;
            return true;
        }

        $path = $this->get_stylesheet_directory();
        if ( $domainpath = $this->get('DomainPath') )
            $path .= $domainpath;
        else
            $path .= '/languages';

        $this->textdomain_loaded = load_theme_textdomain( $textdomain, $path );
        return $this->textdomain_loaded;
    }

上面的代码有问题吗？

更新

感谢以下答案 - 我现在可以看到主题（它没有显示为空白页） - 但我仍然遇到相同的错误......以及更多错误：

Notice: Use of undefined constant Redux_TEXT_DOMAIN - assumed 'Redux_TEXT_DOMAIN' in /var/www/wp-content/themes/rustik3/admin/options.php on line 501

Notice: Use of undefined constant Redux_TEXT_DOMAIN - assumed 'Redux_TEXT_DOMAIN' in /var/www/wp-content/themes/rustik3/admin/options.php on line 502

这是设置$item_info的唯一其他地方：

    $item_info = '<div class="rustik-opts-section-desc"><div style="float: left; margin-right: 20px;"><img width="300px" alt="Current theme preview" src="'.get_option('home').'/wp-content/themes/rustik3/screenshot.png"></div><div style="float: left;">';
    $item_info .= '<p class="rustik-opts-item-data description item-uri">' . __('<strong>Theme URL:</strong> ', Rustik_TEXT_DOMAIN) . '<a href="' . $item_uri . '" target="_blank">' . $item_uri . '</a></p>';
    $item_info .= '<p class="rustik-opts-item-data description item-author">' . __('<strong>Author:</strong> ', Rustik_TEXT_DOMAIN) . ($author_uri ? '<a href="' . $author_uri . '" target="_blank">' . $author . '</a>' : $author) . '</p>';
    $item_info .= '<p class="rustik-opts-item-data description item-version">' . __('<strong>Version:</strong> ', Rustik_TEXT_DOMAIN) . $version . '</p>';
    $item_info .= '<p class="rustik-opts-item-data description item-description">' . $description . '</p>';
    $item_info .= '<p class="rustik-opts-item-data description item-tags">' . __('<strong>Tags:</strong> ', Rustik_TEXT_DOMAIN) . implode(', ', $tags) . '</p>';
    $item_info .= '</div></div>';

Answer 1

根据：http://www.mojo-themes.com/item/rustik-minimalist-e-commerce-ready-theme/

该主题可在 wordpress 3.9 上运行，但也需要 WooCommerce 2.1 插件。你有那个安装吗？ http://wordpress.org/plugins/woocommerce/

定义的常量可能在依赖项中。

Answer 2

public function load_textdomain() {
    if ( isset( $this->textdomain_loaded ) )
        return $this->textdomain_loaded;

    $textdomain = $this->get('TextDomain');
    if ( ! $textdomain ) {
        $this->textdomain_loaded = false;
        return false;
    }

    if ( is_textdomain_loaded( $textdomain ) ) {
        $this->textdomain_loaded = true;
        return true;
    }

    $path = $this->get_stylesheet_directory();
    if ( $domainpath = $this->get('DomainPath') )
        $path .= $domainpath;
    else
        $path .= '/languages';

    define('redux_TEXT_DOMAIN', $textdomain);
    $this->textdomain_loaded = load_theme_textdomain( $textdomain, $path );
    return $this->textdomain_loaded;
}
