The Tokens widget allows you to add shortcodes within the post text. As a result, you can show values from Post, Term, User, Date, WP_Query, System and Option.
Shortcode composition:
- [(open tag);
- post (or user or option, required);
- field name (required, native fields and meta are supported);
- sub field key (optional and multiple, if field is array);
- | ID (optional, if omitted will take the current);
- ? Fallback text (optional, shown if field value is null);
- ] (close tag).
