Template files are PHP files inside your theme such as: single.php
, page.php
. You can learn more about WP template files here.
If you are not familiar with PHP to add code to template files, you can use shortcode to output the meta value in the post content. Simply add:
[rwmb_meta meta_key="FIELD_ID"]
into your post content and you'll see it's displayed in the frontend when you view the post. For more information about the shortcode, please read this documentation.
