profile_update

The "profile_update" hook is a WordPress action hook that is triggered when a user profile is updated or saved. It allows you to perform additional actions or modifications after user profile data has been updated.

The "profile_update" hook is commonly used when you want to extend the functionality of the user profile update process. For example, you can use this hook to send a notification email to the user or log the profile update activity.

Here’s an example usage code for the "profile_update" hook:

// Define a function to be executed on profile update
function my_custom_profile_update($user_id) {
    // Perform additional actions on profile update
    // For example, send an email notification
    wp_mail($user_id, 'Profile Updated', 'Your profile has been successfully updated.');

    // Log the profile update activity
    error_log('User profile updated for user ID: ' . $user_id);
}
add_action('profile_update', 'my_custom_profile_update');

In this example, we define a custom function called "my_custom_profile_update" that takes the user ID as a parameter. Inside the function, we can perform any additional actions we want, such as sending an email notification to the user or logging the update activity using the wp_mail function and error_log respectively.

Finally, we use the add_action function to hook our custom function "my_custom_profile_update" to the "profile_update" hook. Now, whenever a user’s profile is updated, our function will be executed, and the defined actions will take place.

Remember to replace the example actions with your desired functionality to suit your specific needs.
