Introduction

In this article, we will explore how to set a post expiration date and delete a post when it expires in WordPress. We will use a custom function to achieve this functionality, which will be triggered by a specific date stored in a custom Advanced Custom Fields (ACF) field.

Understanding the Problem

When creating content on a WordPress website, it's common to have posts that are only relevant for a specific period. However, managing these posts can be a challenge, especially when it comes to deleting them after a certain period. This is where the concept of post expiration comes in.

The Challenge

In a typical WordPress setup, posts are not automatically deleted after a certain period. This means that you need to manually delete them, which can be time-consuming and prone to errors. Moreover, if you have a large number of posts, it can be difficult to keep track of which ones need to be deleted.

The Solution

To solve this problem, we will create a custom function that will delete a post when the current date is equal to or greater than the expiration date stored in the ACF field. This function will be triggered by a specific date, which will be set by the user.

Creating the Custom Function

To create the custom function, we will use the following code:

function delete_post_by_expiration_date() {
  // Get the current date
  $current_date = date('Y-m-d');

  // Get the post ID from the ACF field
  $post_id = get_field('expiration_date');

  // Get the expiration date from the ACF field
  $expiration_date = get_field('expiration_date', $post_id);

  // Check if the current date is equal to or greater than the expiration date
  if ($current_date >= $expiration_date) {
    // Delete the post
    wp_delete_post($post_id, true);
  }
}

This function uses the get_field function from ACF to retrieve the post ID and expiration date from the ACF field. It then checks if the current date is equal to or greater than the expiration date. If it is, the function deletes the post using the wp_delete_post function.

Adding the Custom Function to the WordPress Loop

To add the custom function to the WordPress loop, we will use the wp_schedule_event function to schedule the function to run at a specific interval. In this case, we will schedule the function to run daily at midnight.

function schedule_delete_post_event() {
  // Schedule the delete post event to run daily at midnight
  wp_schedule_event(time(), 'daily', 'delete_post_event');
}

We will then add the custom function to the WordPress loop using the wp_schedule_event function.

function delete_post_event() {
  // Run the delete post function
  delete_post_by_expiration_date();
}

Adding the Custom Function to the WordPress Cron

To add the custom function to the WordPress cron, we will use the wp_schedule_event function to schedule the function to run at a specific interval. In this case, we will schedule the function to run daily at midnight.

function schedule_delete_post_event() {
  // Schedule the delete post event to run daily at midnight
  wp_schedule_event(time(), 'daily', 'delete_post_event');
}

We will then add the custom function to the WordPress cron using the wp_schedule_event function.

function delete_post_event() {
  // Run the delete post function
  delete_post_by_expiration_date();
}

Testing the Custom Function

To test the custom function, we will create a new post with an expiration date set in the ACF field. We will then wait for the scheduled event to run and check if the post has been deleted.

Conclusion

In this article, we have explored how to set a post expiration date and delete a post when it expires in WordPress. We have created a custom function that uses the ACF field to retrieve the post ID and expiration date, and then deletes the post when the current date is equal to or greater than the expiration date. We have also added the custom function to the WordPress loop and WordPress cron to schedule the function to run at a specific interval.

Additional Tips and Variations

  • To customize the custom function to delete posts based on a specific category or tag, you can modify the get_posts function to retrieve posts based on the desired criteria.
  • To customize the custom function to delete posts based on a specific date range, you can modify the get_posts function to retrieve posts based on the desired date range.
  • To customize the custom function to send a notification to the post author when the post is deleted, you can use the wp_mail function to send an email notification.

Code Snippets

Here are some code snippets that you can use to customize the custom function:

  • To delete posts based on a specific category:
function delete_post_by_category() {
  // Get the current date
  $current_date = date('Y-m-d');

  // Get the post ID from the ACF field
  $post_id = get_field('expiration_date');

  // Get the expiration date from the ACF field
  $expiration_date = get_field('expiration_date', $post_id);

  // Get the post category
  $category = get_the_category($post_id);

  // Check if the current date is equal to or greater than the expiration date
  if ($current_date >= $expiration_date) {
    // Delete the post
    wp_delete_post($post_id, true);
  }
}
  • To delete posts based on a specific date range:
function delete_post_by_date_range() {
  // Get the current date
  $current_date = date('Y-m-d');

  // Get the post ID from the ACF field
  $post_id = get_field('expiration_date');

  // Get the expiration date from the ACF field
  $expiration_date = get_field('expiration_date', $post_id);

  // Get the post date
  $post_date = get_the_date($post_id);

  // Check if the current date is within the date range
  if ($current_date >= $expiration_date && $current_date <= $post_date) {
    // Delete the post
    wp_delete_post($post_id, true);
  }
}
  • To send a notification to the post author when the post is deleted:
function send_notification() {
  // Get the post author
  $author = get_the_author($post_id);

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

  // Send an email notification to the post author
  wp_mail($author, 'Post Deleted', 'Your post "' . $title . '" has been deleted.');
}
