如何製作多國語系檔案

在Omeka S中能切換不同的語言，因此在修改或製作主題/模組時就得考慮加入多國語系，至少做個對應中文與英文

製作方式不難，採用的就是gettext(i18n)的作法

首先需要*.po(zh_TW.po) 如果是繁體中文，就用對應的語言簡稱(zh_TW)

內容大概像這樣

msgid "Close Menu"  //這是原始字串原文
msgstr "關閉選單"  //翻譯後

再來使用po轉檔成的mo檔 線上轉換器

若開發新模組需要在config/module.config.php中新增下面參數，讓OmekaS能讀到你的語系檔位置

'translator' => [
        'translation_file_patterns' => [
            [
                'type' => 'gettext',
                'base_dir' => dirname(__DIR__) . '/language',
                'pattern' => '%s.mo',
                'text_domain' => null,
            ],
        ],
    ],

html要導入多國語系設定需要要先宣告

$translate = $this->plugin('translate');

接著再對應的位置用這種寫法即可

<?= $translate('Close Menu')?>  ///顯示字串關閉選單

在php只要呼叫這樣即可

$translate('Close Menu'),  ///顯示字串關閉選單
