How to Find Book & Taxonomy IDs

Many shortcodes in this plugin require specific IDs to filter content (e.g., displaying only specific books, authors, or categories). Since WordPress hides these IDs by default, here is a quick guide on how to find them.

1. How to Find a Book ID

If you want to display specific books using book_ids="12, 15", follow these steps:

1. Go to your Dashboard and navigate to Books > All Books.
2. Hover your mouse cursor over the Title of the book you need.
3. Look at the bottom-left corner of your browser window. You will see a long URL appearing.
4. Look for the part that says post=NUMBER.
5. That number is your Book ID.

Example: If the URL shows .../post.php?post=158&action=edit, then the Book ID is 158.

2. How to Find Taxonomy IDs

You often need IDs for Categories, Authors, or Series to use attributes like categories_include="5" or authors_include="10".

For Book Categories:

1. Navigate to Books > Book Categories.
2. Hover your mouse over the name of a specific category.
3. Look at the URL at the bottom-left of your browser.
4. Find the part that says tag_ID=NUMBER.
5. That number is the Category ID.

For Book Authors & Series:

The process is exactly the same:

1. Navigate to Books > Book Authors (or Book Series).
2. Hover over the Author or Series name.
3. Look for tag_ID=NUMBER in the URL at the bottom-left.
4. Use that number in your shortcode.

Visual Tip:

• ...taxonomy=book-category&tag_ID=25... → ID is 25
• ...taxonomy=book-author&tag_ID=42... → ID is 42

💡 Pro Tip: Reveal IDs Dashboard-wide

If you find this method tedious, you can install a free plugin like “Reveal IDs” or “Show IDs” from the WordPress repository. These plugins add a dedicated “ID” column to your admin tables, making the numbers visible at a glance without hovering.
