The plugin header must start with /** and include Plugin Name and Version.

2

Add function to get plugins and themes with updates

Add a function named get_update_items that uses get_site_transient('update_plugins') and get_site_transient('update_themes') to retrieve plugins and themes with available updates. Store the results in variables $plugin_updates and $theme_updates.

Wordpress

<?php
/**
 * Plugin Name: Update Manager
 * Version: 1.0
 */

Use get_site_transient to get update info for plugins and themes.

3

Add configuration variable for auto-update control

Add a boolean variable named $enable_auto_update and set it to true to control whether automatic updates are enabled.

Wordpress

 $plugin_updates, 'themes' => $theme_updates);
}

// Your code here

Need a hint?

This variable will help toggle automatic updates on or off.

4

Implement auto-update filter and admin menu

Add a filter hook using add_filter on auto_update_plugin and auto_update_theme that returns the value of $enable_auto_update. Also, add an admin menu page using add_action('admin_menu', 'update_manager_menu') and define update_manager_menu to add a menu page with title Update Manager.

Wordpress

 $plugin_updates, 'themes' => $theme_updates);
}

$enable_auto_update = true;

Use add_filter to control auto-updates and add_menu_page to add an admin page.
