自定义语言切换器

如果您希望设计自定义的 TranslatePress 语言切换器，您可以实现一项功能来帮助您获取使用插件时所需的所有必要信息。

创建 TranslatePress 自定义语言切换器

需要调用的函数是

trp_custom_language_switcher().该函数返回具有以下参数的数组：

• $custom_ls_array[$language_code]['language_name'] – the full language name
• $custom_ls_array[$language_code]['language_code'] – the language code of the respective language
• $custom_ls_array[$language_code]['short_language_name'] –  the language code of the language, the slug which will be used in the url
• $custom_ls_array[$language_code]['flag_link'] – a link to the flag of the respective language
• $custom_ls_array[$language_code]['current_page_url'] – the URL of the current language with the language slug added

以下是定制语言切换器的示例：

在这里您可以看到代码片段：

<?php $array = trp_custom_language_switcher();  ?>
<!-- IMPORTANT! You need to have data-no-translation on the wrapper with the links or TranslatePress will automatically translate them in a secondary language. -->    
<ul data-no-translation>
    <!--  // Check whether TranslatePress can run on the current path or not. If the path is excluded from translation, trp_allow_tp_to_run will be false -->
    <?php if ( apply_filters( 'trp_allow_tp_to_run', true ) ){ ?>
           <?php foreach ($array as $name => $item){ ?>
                <li style="list-style-image: url(<?php echo $item['flag_link'] ?>)"> 
                    <a href="<?php echo $item['current_page_url']?>"> 
                        <span><?php echo $item['short_language_name']. ':' . $item['language_name']?>
                        </span>
                    </a>
                </li>
           <?php } ?>
    <?php } ?>
</ul>

注意：您需要在带有链接的包装器上使用

data-no-translation ，否则 TranslatePress 会自动将它们翻译成第二语言。

您还可以创建自定义语言切换器短代码，然后可以使用类似 [custom-language-switcher]

/*
 * Custom language switcher shortcode
 */

add_shortcode('custom-language-switcher', 'trpc_custom_language_switcher', 10);
function trpc_custom_language_switcher(){
    // Check whether TranslatePress can run on the current path or not. If the path is excluded from translation, trp_allow_tp_to_run will be false
    if ( apply_filters( 'trp_allow_tp_to_run', true ) ){
        $languages = trp_custom_language_switcher();
        $html = "<ul data-no-translation>";
        foreach ($languages as $name => $item) {
            $html .= "<li style='list-style-image: url({$item['flag_link']})'>";
            $html .= "<a href='{$item['current_page_url']}'>";
            $html .= "<span>{$item['language_name']}</span></a></li>";
        }
        $html .= "</ul>";
        return $html;
    }
}
