Create Primary Call to Action Custom Fields for Book Posts

Introduction

As the author owner of your website YOU get to decide what the primary call to action for your book posts should be.

If you’re a direct seller you may want your primary call to action to send visitors to your online store to purchase your book.

If you’re an Amazon exclusive author you may want your primary call to action button to use a smart, geographically aware hyperlink to the visitors nearest Amazon store. 

We are going to use custom fields to define the primary call to action button to say and go wherever you like for each individual book.

Add the Primary Call to Action Group

We are finally going to use a different field type than number. In fact we are going to use a special field type. We’ll start from the WordPress Admin side bar and go to ACF then Field Groups and add a new field.

General Settings

• Set the field type to GROUP
• Enter Primary CTA Button as the field label
• Accept the default field name

Validation

Make this field group a required field.

The Group field type provides a way to structure fields into groups. It assists in better organising the edit screen UI as well as the data.

We won’t enter any information into the Group field type from the Book Post. Instead we will add sub-fields for our data entry. These subfields are just like regular custom field types but organised under the Group field we just set up.

I’ll add the two required sub-fields to show you this in action.

Primary CTA Button Text Sub-Field

• In the sub-fields meta box click the + Add new field button
• The field type is TEXT
• The field label is Primary CTA Button Text
• Accept the default field name
• Make this a required field
• Add the instruction. Text to display on the Primary CTA Button.

Primary CTA BUtton URL Sub-Field

• Add a new sub field
• The field type is URL
• The field label is Primary CTA Button URL
• Accept the default field name
• Make this a required field
• Save changes

Update the Book

Let’s go see what this Group field with it’s subfields looks like on our Books Custom Post Type

We now have the option to add the button text and url for our Primary call to action. I’m going to use this book book to demonstrate a free-first-in-series strategy later in this course so I’ll add the following values

• Get Your Free eBook
• And the url to the sign up page
• Save draft

Summary

This lesson covered how to create and configure a Primary Call-to-Action field group with ACF, including sub-fields for button text and URL. By adding these fields to your Books Custom Post Type, you gain full control over the CTAs on each book page, ensuring they align with your sales or marketing strategies. This customisation enhances your site’s flexibility, professionalism, and ability to convert visitors into readers or customers.
