destoon代码从头到尾捋一遍

2019-01-10 212浏览

Destoon® B2B网站管理系统(以下简称destoon)由西安嘉客信息科技有限责任公司独立研发并推出,对其拥有完全知识产权,中国国家版权局计算机软件著作权登记号:2009SR037570。

系统使用当前流行的PHP语言开发,以MySQL为数据库,采用B/S架构,MVC模式开发。融入了模型化、模板、缓存、AJAX、SEO等前沿技术。与同类产品相比,系统功能更加强大、使用更加简单、运行更加稳定、安全性更强,效率更高,用户体验更好。系统开源发布,便于二次开发、功能整合、个性修改。

代码首先包含common.inc.php文件

在common.inc.php文件中,首先定义常量。

define('IN_DESTOON', true);

define('IN_ADMIN', defined('DT_ADMIN') ? true : false);

define('DT_ROOT', str_replace("\\", '/', dirname(__FILE__)));

if(defined('DT_REWRITE')) include DT_ROOT.'/include/rewrite.inc.php';//是否定义了url伪静态?

$CFG = array();//网站整体配置信息

require DT_ROOT.'/config.inc.php';//-----------------网站配置文件

define('DT_PATH', $CFG['url']);

define('DT_DOMAIN', $CFG['cookie_domain'] ? substr($CFG['cookie_domain'], 1) : '');

define('DT_WIN', strpos(strtoupper(PHP_OS), 'WIN') !== false ? true: false);

define('DT_CHMOD', ($CFG['file_mod'] && !DT_WIN) ? $CFG['file_mod'] : 0);

define('DT_URL', $CFG['url']);//Fox 3.x

define('DT_LANG', $CFG['language']);

define('DT_KEY', $CFG['authkey']);

define('DT_CHARSET', $CFG['charset']);

define('DT_CACHE', $CFG['cache_dir'] ? $CFG['cache_dir'] : DT_ROOT.'/file/cache');

define('DT_SKIN', DT_PATH.'skin/'.$CFG['skin'].'/');

define('SKIN_PATH', DT_PATH.'skin/'.$CFG['skin'].'/');//For 2.x

define('VIP', $CFG['com_vip']);

define('errmsg', 'Invalid Request');

随后加载网站基本功能

$L = array();

include DT_ROOT.'/lang/'.DT_LANG.'/lang.inc.php';//语言信息

require DT_ROOT.'/version.inc.php';

require DT_ROOT.'/include/global.func.php';//--------全局函数

require DT_ROOT.'/include/tag.func.php';//-----------标签函数

require DT_ROOT.'/api/im.func.php';//----------------聊天工具

require DT_ROOT.'/api/extend.func.php';//------------自己写的扩展函数

if(!$MQG && $_POST) $_POST = daddslashes($_POST);

if(!$MQG && $_GET) $_GET = daddslashes($_GET);

if(function_exists('date_default_timezone_set')) date_default_timezone_set($CFG['timezone']);

$DT_PRE = $CFG['tb_pre'];

$DT_QST = $_SERVER['QUERY_STRING'];//----------------querystring

$DT_TIME = time() + $CFG['timediff'];//--------------当前时间

$DT_IP = get_env('ip');

$DT_URL = get_env('url');

$DT_REF = get_env('referer');

$DT_BOT = is_robot();

链接数据库,建立缓存。

header("Content-Type:text/html;charset=".DT_CHARSET);

require DT_ROOT.'/include/db_'.$CFG['database'].'.class.php';//加载数据库类

require DT_ROOT.'/include/cache_'.$CFG['cache'].'.class.php';//加载缓存类

if($_POST) extract($_POST, EXTR_SKIP);//解析post请求的数据

if($_GET) extract($_GET, EXTR_SKIP);//解析get请求的数据

$db_class = 'db_'.$CFG['database'];

$db = new $db_class;

$db->halt = (DT_DEBUG || IN_ADMIN) ? 1 : 0;

$db->pre = $CFG['tb_pre'];

$db->connect($CFG['db_host'], $CFG['db_user'], $CFG['db_pass'], $CFG['db_name'], $CFG['db_expires'], $CFG['db_charset'], $CFG['pconnect']);

$dc = new dcache();

$dc->pre = $CFG['cache_pre'];

加载模块的基本配置

$DT = $MOD = $EXT = $CSS = $DTMP = $CAT = $ARE = $AREA = array();

$CACHE = cache_read('module.php');

if(!$CACHE) {

//没有缓存模块,就读取缓存模块。

require_once DT_ROOT.'/admin/global.func.php';

require_once DT_ROOT.'/include/post.func.php';

require_once DT_ROOT.'/include/cache.func.php';

   cache_all();

$CACHE = cache_read('module.php');

}

$DT = $CACHE['dt'];

$MODULE = $CACHE['module'];

$EXT = cache_read('module-3.php');

加载模块,读取模块信息,引入模块文件

if(!isset($moduleid)) {

$moduleid = 1;

$module = 'destoon';

} else if($moduleid == 1) {

$module = 'destoon';

} else {

$moduleid = intval($moduleid);

$module = $MODULE[$moduleid]['module'];

$MOD = $moduleid == 3 ? $EXT : cache_read('module-'.$moduleid.'.php');

include DT_ROOT.'/lang/'.DT_LANG.'/'.$module.'.inc.php';

}

$forward = isset($forward) ? urldecode($forward) : $DT_REF;//------------来源页面

$action = isset($action) ? trim($action) : '';//-------------动作指令

//判断用户登录

$destoon_auth = get_cookie('auth');

if($destoon_auth) {

$_dauth = explode("\t", decrypt($destoon_auth, md5(DT_KEY.$_SERVER['HTTP_USER_AGENT'])));
