WordPress：在我的插件中获取pll_the_languages

Question

如何将语言输入WordPress的自定义插件中？ 当我调用pll_the_languages（）时，输出我的错误。 也许我应该称呼某种全球方法？

我的插件代码：

/**

 * @author            Sergey Samokhvalov

/* Registrate admin js and styles */

add_action( 'admin_enqueue_scripts', 'reg_amin_js' );
function reg_amin_js( $page ) {
  // change to the $page where you want to enqueue the script
  if( $page == 'post-new.php' || $page == 'post.php' || $page == 'edit.php' ) {
    // Enqueue WordPress media scripts
    wp_enqueue_media();
    
    // Enqueue custom script that will interact with wp.media
    wp_enqueue_script( 'woocommerce_admin-scripts', plugins_url('/admin/js/admin.js',__FILE__ ), array('jquery') );
    // Enqueue custom styles for admin panel
    wp_enqueue_style('woocommerce_admin-styles', plugins_url('/admin/css/style.css', __FILE__ ));
    
  }
}

我的问题得到了解决。
您应该使用Admin_init操作：

    function plugin_pll_register_string() {
        if ( function_exists( 'pll_register_string' ) ) {
      pll_register_string('woocommerce-admin-ajax-strings', 'Update');
      pll_register_string('woocommerce-admin-ajax-strings', 'Published');
      pll_register_string('woocommerce-admin-ajax-strings', 'Product is updated!');
        }
    }
    add_action( 'admin_init', 'plugin_pll_register_string' );
