Introduction

In the world of WordPress development, custom post types have become an essential feature for creating unique and dynamic content structures. However, as the complexity of your website grows, so does the need for automated processes that streamline tasks and enhance user experience. One such process is sending email notifications to authors when a custom post type is saved. In this article, we will delve into the world of custom post types, functions, and email notifications, and explore how to implement this feature using WordPress hooks and actions.

Understanding Custom Post Types

Before we dive into the code, let's take a moment to understand what custom post types are and how they work. Custom post types are a feature in WordPress that allows developers to create new content types beyond the standard post, page, and attachment types. They can be used to create custom content structures, such as products, events, or documents, and can be tailored to meet the specific needs of your website.

In our case, we have a custom post type called "documents" that allows users to add documents with ACF repeater fields. The documents are then displayed in a frontend view, making it easy for users to access and view the documents.

The Need for Email Notifications

As the author of the documents, it's essential to keep them informed about new documents being added or updated. This is where email notifications come in. By sending an email notification to the author when a custom post type is saved, we can ensure that they stay up-to-date with the latest documents and can take action accordingly.

Implementing Email Notifications

To implement email notifications for custom post type authors, we will use the WordPress hook save_post and the wp_insert_post action. The save_post hook is triggered when a post is saved, and the wp_insert_post action is fired when a new post is inserted.

Here's an example code snippet that demonstrates how to send an email notification to the author when a custom post type is saved:

function send_email_notification_on_save_post($post_id) {
  // Get the post type
  $post_type = get_post_type($post_id);

// Check if the post type is 'documents'
if ($post_type == 'documents') {
// Get the post author
$author = get_post_field('post_author', $post_id);


// Get the post title
$title = get_the_title($post_id);

// Get the post content
$content = get_the_content($post_id);

// Send an email notification to the author
$to = get_the_author_meta('email', $author);
$subject = 'New Document Added: ' . $title;
$message = 'A new document has been added: ' . $title . '. You can view it here: ' . get_permalink($post_id);
wp_mail($to, $subject, $message);



}
}


// Hook into the save_post action
add_action('save_post', 'send_email_notification_on_save_post');

This code snippet uses the save_post hook to trigger the send_email_notification_on_save_post function when a post is saved. The function checks if the post type is '' and if so, sends an email notification to the author with the post title and permalink.

Customizing the Email Notification

The email notification sent to the author can be customized to include additional information or change the format of the email. For example, you can add a link to the document or include a summary of the document's content.

Here's an updated code snippet that includes a link to the document and a summary of the document's content:

function send_email_notification_on_save_post($post_id) {
  // Get the post type
  $post_type = get_post_type($post_id);

// Check if the post type is 'documents'
if ($post_type == 'documents') {
// Get the post author
$author = get_post_field('post_author', $post_id);


// Get the post title
$title = get_the_title($post_id);

// Get the post content
$content = get_the_content($post_id);

// Get the document link
$link = get_permalink($post_id);

// Get the document summary
$summary = wp_trim_words($content, 20);

// Send an email notification to the author
$to = get_the_author_meta('email', $author);
$subject = 'New Document Added: ' . $title;
$message = 'A new document has been added: ' . $title . '. You can view it here: ' . $link . '. Here is a summary of the document: ' . $summary;
wp_mail($to, $subject, $message);



}
}


// Hook into the save_post action
add_action('save_post', 'send_email_notification_on_save_post');

This updated code snippet includes a link to the document and a summary of the document's content in the email notification.
