The snippet checks, if Timber is installed, if not, you can’t activate the plugin:
class MyPlugin {
public function __construct() {
register_activation_hook( __FILE__, array($this, 'plugin_activation_check' ) );
}
function plugin_activation_check() {
if (!is_plugin_active('timber-library/timber.php')) {
@ deactivate_plugins( plugin_basename( __FILE__ ) );
wp_die( 'This plugin requires TIMBER to be installed. Please install before activate this plugin.' );
}
}
}
new MyPlugin();
