我正在尝试使用add\\u操作将HTML输出添加到插件的前端区域，下面是插件的代码片段

<ul class="dashboard-links">
    <li><a href="<?php echo $dashboard_links[\'commissions\'] ?>"><?php _e( \'Commissions\', \'yith-woocommerce-affiliates\' ) ?></a></li>
    <li><a href="<?php echo $dashboard_links[\'clicks\'] ?>"><?php _e( \'Clicks\', \'yith-woocommerce-affiliates\' ) ?></a></li>
    <li><a href="<?php echo $dashboard_links[\'payments\'] ?>"><?php _e( \'Payments\', \'yith-woocommerce-affiliates\' ) ?></a></li>
    <li><a href="<?php echo $dashboard_links[\'generate_link\'] ?>"><?php _e( \'Generate link\', \'yith-woocommerce-affiliates\' ) ?></a></li>
    <li><a href="<?php echo $dashboard_links[\'settings\'] ?>"><?php _e( \'Settings\', \'yith-woocommerce-affiliates\' ) ?></a></li>
    <?php do_action( \'yith_wcaf_after_dashboard_links\', $dashboard_links ) ?>
</ul>

我试图通过在函数中添加下面编写的代码片段来扩展它。php

function add_link_to_aff() {
    $html_output =  "<li><a href=\'#\'><?php _e( \'Test\', \'yith-woocommerce-affiliates\' ) ?></a></li>";
    return $html_output;  
}
add_action( \'yith_wcaf_after_dashboard_links\', \'add_link_to_aff\', 10 );

这是我g的片段，我也试着传递$dashboard_links 但它不起作用。

function add_link_to_aff() {
    $html_output =  "<li><a href=\'#\'>" .  __( \'Test\', \'yith-woocommerce-affiliates\' ) .  "</a></li>";
    echo $html_output;  
}
add_action( \'yith_wcaf_after_dashboard_links\', \'add_link_to_aff\', 10 );
