# Automatic updates (Auto-update)

Part of the doc set: [Hưng Phát Laptop (Theme)](https://phatdev.net/en/docs/hungphat-laptop.md)

> Set a license key in wp-config to receive new versions directly from phatdev.net, with one-click updates in wp-admin.

The theme supports **self-hosted automatic updates**: when a new version is available on phatdev.net, WordPress shows an update notice right in the admin - one click and you're done, with no manual file download.

## Requirement: set a license key
This feature only works when the site has a **license key**. Open the site's `wp-config.php` file and add this line:

```php
define( 'HP_UPDATE_LICENSE', 'HPLIC-xxxxxxxxxxxxxxxx' );
```

- The key is issued by Hưng Phát specifically for your **domain name** (one key per site).
- Place it **above** the line `/* That's all, stop editing! */`.
- **Without a key**, the feature switches itself off (safe, no errors).

## Check and update
1. Go to **Dashboard → Updates**, or **Appearance → Themes**.
2. If a new version exists, WordPress shows "**New version available**".
3. Click **Update now** - the system downloads the new version from phatdev.net (SHA-256 signed, license checked against the domain) and safely installs over the old one.

## How it works (summary)
- WordPress asks phatdev.net "is there a new version?" (sending the key + domain). The server checks the license and returns the latest version + a download link.
- The information is **cached for 6 hours**, and refreshed automatically after an update completes.
- Your data and settings are **not affected** - only the source code is replaced.

> **Not seeing the update notice?** Check that: (1) `HP_UPDATE_LICENSE` is set correctly; (2) the key is still valid for the right domain; (3) wait for the 6-hour cache to expire, or go to **Dashboard → Updates** and click **Check again**. If it still doesn't work, update manually by following the **Manual installation** article.
