Bnfw [post_term] Shortcode

The BNFW plugin shortcode, ‘post_term’, retrieves and displays the names of terms associated with a specific post. It accepts two parameters: ‘taxonomy’ and ‘id’. The ‘taxonomy’ parameter specifies the type of terms to retrieve, while ‘id’ denotes the post’s ID. The shortcode returns a comma-separated list of term names. In case of an error, it returns an empty string.

Shortcode: [post_term]

Parameters

Here is a list of all possible post_term shortcode parameters and attributes:

• taxonomy – specifies the type of taxonomy to retrieve terms from
• id – the unique identifier of the post to get terms for

Examples and Usage

Basic example – A basic usage of the shortcode to retrieve terms from a specific taxonomy related to a post. In this example, we are retrieving categories (taxonomy) related to the post with the ID of 1.

[post_term taxonomy="category" id="1" /]

Advanced examples

Retrieving tags (taxonomy) related to the post with the ID of 2. If there are multiple tags, they will be returned as a comma-separated list.

[post_term taxonomy="post_tag" id="2" /]

Another advanced example could be retrieving a custom taxonomy. Suppose we have a custom taxonomy named “genre” for a custom post type “book”. We can retrieve the genres related to a book post with the ID of 3 like this:

[post_term taxonomy="genre" id="3" /]
