http://blog.sixi.ml/plus/15.htmlHYAPP:465202

用途：防止小型空间提供商提供给其它人的空间，别人做的网站存在漏洞，导致旁注，使站点挂！

文件名：t_hook t_bottom_box.hook

请在 View\admin\footer.html开头中增加{hook t_bottom_box}

if (pathinfo($_SERVER['SCRIPT_FILENAME'], PATHINFO_BASENAME) != 'index.php') {
	ref_check();
}

function ref_check() {
	$referer_url = isset($_SERVER['HTTP_REFERER']) ? filter_var($_SERVER['HTTP_REFERER'], FILTER_VALIDATE_URL) : NULL;

	//如果POST提交没有任何来源，则直接拒绝
	if ($_SERVER['REQUEST_METHOD'] === 'POST' && empty($referer_url)) {
		header('HTTP/1.0 403 Forbidden');
		echo '<h1>Forbidden</h1>';
		exit();
	}

	//只验证POST提交，不验证GET提交
	if ($_SERVER['REQUEST_METHOD'] === 'POST') {
		$referer_host = parse_url($referer_url, PHP_URL_HOST);
		$referer_path = parse_url($referer_url, PHP_URL_PATH);
		if (substr($referer_path, -1) === '/') {
			$referer_path .= 'index.php';
		}
		$referer_path = dirname($referer_path);

		$admin_url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
		$admin_host = $INDEX_PATH!/admin
		$admin_path = $INDEX_PATH!
		if (substr($admin_path, -1) === '/') {
			$admin_path .= 'index.php';
		}
		$admin_path = dirname($admin_path);

		if (REF_CHECK_DEBUG) {
			echo "Ref URL: {$referer_url}<br />\r\n";
			echo "Ref Host: {$referer_host}<br />\r\n";
			echo "Ref Path: {$referer_path}<br />\r\n";
			echo "Admin Host: {$admin_host}<br />\r\n";
			echo "Admin Path: {$admin_path}<br />\r\n";
		}

		//如果来源地址和后台地址不符，则拒绝
		if ($admin_host != $referer_host ||
			$admin_path != $referer_path) {
			header('HTTP/1.0 403 Forbidden');
			echo '<h1>Forbidden</h1>';
			exit();
		}
	}
}

暂时只支持官方模板，如果需要其他模板支持，请在模板的f.html （footer.html\footer.php……）中加入{hook t_bottom_box}
