What is WordPress Hook: heartbeat_received
The WordPress hook “heartbeat_received” is a crucial part of the WordPress heartbeat API. This hook is used to manage the communication between the user’s browser and the server, allowing for real-time updates and notifications within the WordPress dashboard.
Understanding the Hook: heartbeat_received
The “heartbeat_received” hook is located within the wp-admin/admin-ajax.php file and is responsible for processing the data sent from the user’s browser to the server. It is an essential component for enabling real-time features such as post locking, session management, and update notifications within the WordPress dashboard.
Hook Parameters (if applicable): heartbeat_received
The “heartbeat_received” hook does not accept any specific parameters. It simply processes the data sent from the user’s browser to the server and triggers the necessary actions based on the received information.
Hook Doesn’t Work: heartbeat_received
If the “heartbeat_received” hook is not functioning as expected, it could be due to conflicts with other plugins or themes that are interfering with the heartbeat API. It is recommended to deactivate all plugins and switch to a default theme to troubleshoot the issue. Additionally, checking for any errors in the browser console or server logs can provide valuable insights into the root cause of the problem.
Best Practices & Usage Notes (if applicable): heartbeat_received
When utilizing the “heartbeat_received” hook, it is important to consider the frequency and volume of data being transmitted between the browser and the server. Excessive use of the heartbeat API can lead to increased server load and potential performance issues. It is advisable to use the heartbeat API sparingly and only for essential real-time features within the WordPress dashboard.
Usage Example: heartbeat_received
“`php
add_action( ‘heartbeat_received’, ‘custom_heartbeat_processing’, 10, 2 );
function custom_heartbeat_processing( $response, $data ) {
// Custom processing of heartbeat data
return $response;
}
“`
In this example, the “heartbeat_received” hook is used to trigger the custom_heartbeat_processing function, which processes the data received from the user’s browser and returns the appropriate response. This demonstrates a fundamental use case of the “heartbeat_received” hook within WordPress functions.
