# ZAPHandler Interface
|

|------|--------|
|
||
|
|
| **`lib/ZAPHandler.interface.php`** | **Created** — defines `ZAPHandler` interface with `public function getContent()` |
|
||
|
|
| **`lib/ZAPHome.class.php`** | Added `implements ZAPHandler` |
|
||
|
|
| **`lib/ZAPDisplay.class.php`** | Added `implements ZAPHandler` |
|
||
|
|
| **`lib/ZAPZap.class.php`** | Added `implements ZAPHandler` |
|
||
|
|
| **`lib/ZAPController.class.php`** | Added `instanceof ZAPHandler` guard inside `fetch()` before calling `getContent()` |
|
||
|
|
|
||
|
|
### How it works
|
||
|
|
|
||
|
|
- Any class named `ZAP{Mode}` in `lib/` is autoloaded and instantiated by `ZAPController`
|
||
|
|
- The controller now checks `$this->action instanceof ZAPHandler` **before** calling `getContent()`
|
||
|
|
- If a handler forgets to implement the interface, you get a clear `die()` message instead of a cryptic runtime error
|
||
|
|
- The interface file uses the `.interface.php` naming convention, which the existing autoloader already handles (it checks `.interface.php` first, then `.class.php`)
