WP_Customize_Manager::get_lock_user_data() in WordPress

The function WP_Customize_Manager::get_lock_user_data() in WordPress

In WordPress, the function WP_Customize_Manager::get_lock_user_data() is part of the customization system that allows us to retrieve information related to users who are currently working on customizations or settings. This function helps us in situations where multiple users are editing or customizing simultaneously, providing better insights into ongoing activities.

One interesting aspect of this function is that it can retrieve information and details about users from the database efficiently. In other words, if a user is busy customizing a specific section of the site and another person is also performing the same task, this function can indicate which users are currently editing and when that lock will be released.

Imagine a development team working on a shared project. In such cases, managing locks and ensuring that only one person is editing at a specific time can be very important. The function get_lock_user_data() simplifies this process for us.

Overall, using this function in plugins or themes can enhance the user experience and ensure that data integrity and safety are preserved. Now let's take a look at the code for this function and how to use it.

Example Code

$customize_manager = new WP_Customize_Manager();
$lock_data = $customize_manager->get_lock_user_data();
if ( ! empty( $lock_data ) ) { 
    foreach ( $lock_data as $data ) { 
        echo 'User: ' . esc_html( $data->user_login ) . ' is currently editing.';
    } 
} else { 
    echo 'No user is currently editing.';
}
