我在主题定制器中有一个自定义字段，允许定义自己的版权信息。我创建了一个显示当前年份的短代码。当有人将短代码粘贴到textarea中时，如何使其工作？

我使用Kirki框架创建主题选项。

Kirki::add_field( \'my_customizer\', array(
  \'type\'     => \'editor\',
  \'settings\' => \'copyright\',
  \'label\'    => __( \'Content\', \'mytheme\' ),
  \'section\'  => \'section_footer\',
  \'default\'  => __( \'Copyright ⓒ All rights reserved.\', \'mytheme\' ),
  \'description\' => __( \'You can use [current-year] shortcode if you want.\', \'mytheme\' ),
) );

要显示以上选项，我将其添加到页脚。php：

echo Kirki::get_option( \'my_customizer\', \'copyright\' );

我在网站上看到的内容：

Copyright ⓒ [current-year] All rights reserved.
All rights reserved. ⓒ [current-year] by XYZ 
All rights reserved. ⓒ 2016 - [current-year]

我需要实现的目标：

Copyright ⓒ 2019 All rights reserved.
All rights reserved. ⓒ 2019 by XYZ 
All rights reserved. ⓒ 2016 - 2019

有什么解决方案/想法吗？谢谢

$saved_shortcode = get_option( \'my_customizer\', \'copyright\' );
if ( $saved_shortcode && is_string( $saved_shortcode ) ) {
echo do_shortcode( $saved_shortcode );
}
