To implement real-time updates with the WordPress Heartbeat API, you can follow these steps:
- Understand the WordPress Heartbeat API: The Heartbeat API is a built-in feature of WordPress that allows real-time communication between a user's browser and the server. It enables features like autosave, post locking, and real-time update notifications.
- Choose the suitable location: Decide where you want to implement real-time updates. It can be on the front end for user interactions or in the WordPress admin dashboard.
- Hook into the API: To use the Heartbeat API, you need to register your JavaScript code with it using the appropriate hooks. WordPress provides hooks like 'heartbeat-send', 'heartbeat-tick', and 'heartbeat-received'.
- Define your JavaScript actions: Determine what actions you want to perform when a real-time update is triggered. This could be updating a particular section of your website or displaying a notification.
- Create JavaScript handlers: Write JavaScript functions that handle your defined actions when Heartbeat API events occur. These functions will be registered with the Heartbeat API using the hooks mentioned in step 3.
- Use jQuery to make AJAX calls: With the help of jQuery, you can make AJAX calls to the server to retrieve updated data. This data can then be processed and used to update the desired elements on the page.
- Work with heartbeat-send: Use the 'heartbeat-send' hook to send information from the client browser to the server. You can include data such as the current screen, user's actions, or any other relevant information.
- Work with heartbeat-tick: The 'heartbeat-tick' hook runs on every heartbeat interval defined by WordPress. Here, you can check for any updates on the server and trigger the necessary actions in your JavaScript handlers.
- Work with heartbeat-received: The 'heartbeat-received' hook can be used to process any data sent back from the server during the AJAX call. You can update the UI based on this data.
- Debug and optimize: Test your implementation thoroughly to ensure that real-time updates are working as expected. Monitor server performance to identify and optimize any performance issues.
Remember to review the WordPress Heartbeat API documentation for more detailed information on each step.

What steps should be taken if the Heartbeat API is causing high CPU usage?
If the Heartbeat API is causing high CPU usage, you can take the following steps to resolve the issue:
- Identify the cause: Determine if the Heartbeat API is indeed the cause of the high CPU usage. You can use tools like the Query Monitor plugin or the developer console in your browser to identify which scripts or requests are consuming the most resources.
- Evaluate the plugins: Check if any plugins or themes on your website are using the Heartbeat API excessively. Some plugins may use it for real-time notifications or other features that might result in constant requests to the server, leading to high CPU usage.
- Disable Heartbeat API: If you find that the Heartbeat API is indeed causing the issue, you can disable it or reduce its frequency. Several plugins are available for managing the Heartbeat API, such as Heartbeat Control or WP Disable, which allow you to adjust its interval or completely disable it.

How to exclude specific user roles from Heartbeat API requests?
To exclude specific user roles from Heartbeat API requests, you can use the heartbeat_received and heartbeat_settings filters in WordPress. Here's an example code snippet that demonstrates how to exclude specific user roles:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
// Exclude specific user roles from Heartbeat API requests function exclude_roles_from_heartbeat( $settings ) { // Get the current user $current_user = wp_get_current_user(); // Define the roles to be excluded $excluded_roles = array( 'editor', 'subscriber' ); // Check if the current user role is in excluded roles if ( array_intersect( $current_user->roles, $excluded_roles ) ) { $settings['interval'] = 0; // Set the interval to 0 for excluded roles } return $settings; } add_filter( 'heartbeat_settings', 'exclude_roles_from_heartbeat' ); // Disable Heartbeat API completely for specific user roles function disable_heartbeat_for_roles( $response, $data ) { // Get the current user $current_user = wp_get_current_user(); // Define the roles to be excluded $excluded_roles = array( 'editor', 'subscriber' ); // Check if the current user role is in excluded roles if ( array_intersect( $current_user->roles, $excluded_roles ) ) { $response['wp-heartbeat'] = false; // Disable the Heartbeat API for excluded roles } return $response; } add_filter( 'heartbeat_received', 'disable_heartbeat_for_roles', 10, 2 ); |
This code snippet checks the role of the current user and then adjusts the Heartbeat API settings accordingly. For the excluded roles, it sets the Heartbeat interval to 0, effectively disabling the Heartbeat API for those roles.
How to monitor Heartbeat API activity in the browser console?
To monitor Heartbeat API activity in the browser console, you can follow these steps:
- Open your web browser (e.g., Google Chrome, Mozilla Firefox).
- Navigate to the webpage where the Heartbeat API is being used.
