如何在WordPress中使用metabox中的短代码？

Question

I've created a custom metabox using this example. When the admin-user enters a shortcode in my metabox, the shortcode displays on my front-end as plain text such as:

[menu]

How can I make sure WordPress parses the shortcode so an actual menu is outputted?

I'm using this in my page.php template to display the contents of my custom metabox:

echo get_post_meta( get_the_ID(), '_my_custom_meta_value_key', true );

You can simply use do_shortcode provided by WordPress. This can be used to manually search through the given string for shortcodes.

According to docs for do_shortcode:

Searches content for shortcodes and filters shortcodes through their hooks.

This is how you can do it:

$shortcode = get_post_meta( get_the_ID(), '_my_custom_meta_value_key', true );

echo do_shortcode($shortcode);
