Using term_description in WordPress to retrieve a term’s description

The term_description function in WordPress is a built-in function that retrieves the description of a certain term. This term could be a category, a tag, or a term from a custom taxonomy.

This function can be useful in various situations. For instance, when displaying the archive page for a specific category or tag, the description of that category or tag can be fetched and displayed on the page using the term_description function. This can provide visitors with additional context about the content they are viewing.

Also, when developing a custom taxonomy, the term_description function can be used to retrieve and display the description of terms belonging to that taxonomy.

It’s important to note that the term_description function will return an empty string if the term does not have a description. Therefore, it’s recommended to check if the returned value is not empty before using it.

In addition, the term_description function is sanitized with the term_description filter. This means that the function is safe to use in terms of security, as it will automatically escape any potentially harmful code in the term description.

The WordPress term_description function accepts two parameters:

  • $term (int): This is an optional parameter that represents the Term ID. By default, it refers to the current term ID.
  • $deprecated (null): This is an optional parameter that is set to null by default. It is deprecated and is not used.

If the function doesn’t accept any parameters, this will be explicitly stated.
