Ecshop探究之index.php

引言：我们就从首页切入，进行Ecshop的研究。

Ecshop是电子商务解决方案，很成熟很完善。但是要学会进行二次开发。什么帮助文档都不需要，直接代码入手。代码就是最好的帮助文档。

直接代码：

index.php剖析

define('IN_ECS', true);
require(dirname(__FILE__) . '/includes/init.php');

首先是定义一个常量，标识已经进入ECS。然后引入includes目录下的init.php文件。

includes里面是一些核心文件，核心类。

好，我们直接进入init.php文件下探索个究竟。

require(ROOT_PATH . 'data/config.php');

init.php中引入了一些配置

<?php
// database host
$db_host   = "localhost:3306";

// database name
$db_name   = "ecshop";

// database username
$db_user   = "root";

// database password
$db_pass   = "";

// table prefix
$prefix    = "ecs_";

$timezone    = "Asia/Shanghai";

$cookie_path    = "/";

$cookie_domain    = "";

$session = "1440";

define('EC_CHARSET','utf-8');

define('ADMIN_PATH','admin');

define('AUTH_KEY', 'this is a key');

define('OLD_AUTH_KEY', '');

define('API_TIME', '');

?>

上面是config.php中的代码，主要是配置了一些数据库的信息。

包括数据库名，用户密码，前缀等等。后面会用到这些信息。

我们来继续研究init.php

require(ROOT_PATH . 'includes/inc_constant.php');
require(ROOT_PATH . 'includes/cls_ecshop.php');
require(ROOT_PATH . 'includes/cls_error.php');
require(ROOT_PATH . 'includes/lib_time.php');
require(ROOT_PATH . 'includes/lib_base.php');
require(ROOT_PATH . 'includes/lib_common.php');
require(ROOT_PATH . 'includes/lib_main.php');
require(ROOT_PATH . 'includes/lib_insert.php');
require(ROOT_PATH . 'includes/lib_goods.php');
require(ROOT_PATH . 'includes/lib_article.php');

init.php引入了很多核心文件和类。可以调用其中的方法，初始化对象等等。

/* 创建 ECSHOP 对象 */
//echo $db_name;exit;
$ecs = new ECS($db_name, $prefix);
define('DATA_DIR', $ecs->data_dir());
define('IMAGE_DIR', $ecs->image_dir());

/* 初始化数据库类 */
require(ROOT_PATH . 'includes/cls_mysql.php');
$db = new cls_mysql($db_host, $db_user, $db_pass, $db_name);
$db->set_disable_cache_tables(array($ecs->table('sessions'), $ecs->table('sessions_data'), $ecs->table('cart')));
$db_host = $db_user = $db_pass = $db_name = NULL;

/* 创建错误处理对象 */
$err = new ecs_error('message.dwt');

/* 载入系统参数 */
$_CFG = load_config();

/* 载入语言文件 */
require(ROOT_PATH . 'languages/' . $_CFG['lang'] . '/common.php');

进行一些初始化操作，包括创建ecshop对象，连接数据库，创建错误处理对象，载入系统参数与语言文件等等。
这里就不深入追究了。想追究的话，可以进一步深入探寻。

if (!defined('INIT_NO_USERS'))
{
    /* 初始化session */
    include(ROOT_PATH . 'includes/cls_session.php');

    $sess = new cls_session($db, $ecs->table('sessions'), $ecs->table('sessions_data'));

    define('SESS_ID', $sess->get_session_id());
}

引入session类，并进行初始化。

if (!defined('INIT_NO_SMARTY'))
{
    header('Cache-control: private');
    header('Content-type: text/html; charset='.EC_CHARSET);

    /* 创建 Smarty 对象。*/
    require(ROOT_PATH . 'includes/cls_template.php');
    $smarty = new cls_template;

    $smarty->cache_lifetime = $_CFG['cache_time'];
    $smarty->template_dir   = ROOT_PATH . 'themes/' . $_CFG['template'];
    //echo $_CFG['template'];exit;
    $smarty->cache_dir      = ROOT_PATH . 'temp/caches';
    $smarty->compile_dir    = ROOT_PATH . 'temp/compiled';

    if ((DEBUG_MODE & 2) == 2)
    {
        $smarty->direct_output = true;
        $smarty->force_compile = true;
    }
    else
    {
        $smarty->direct_output = false;
        $smarty->force_compile = false;
    }

    $smarty->assign('lang', $_LANG);
    $smarty->assign('ecs_charset', EC_CHARSET);
    if (!empty($_CFG['stylename']))
    {
        $smarty->assign('ecs_css_path', 'themes/' . $_CFG['template'] . '/style_' . $_CFG['stylename'] . '.css');
    }
    else
    {
        $smarty->assign('ecs_css_path', 'themes/' . $_CFG['template'] . '/style.css');
    }

}

配置smarty信息。Ecshop中运用的是smarty模板技术，这与ZF框架还是有一分相似的。

这些配置信息，都是从上面的数据中获取的，默认的模板是default，可以到相应的文件中进行修改。注意会有缓存。要清理缓存才能看到效果。

if (!defined('INIT_NO_USERS'))
{
    /* 会员信息 */
    $user =& init_users();

    if (!isset($_SESSION['user_id']))
    {
        /* 获取投放站点的名称 */
        $site_name = isset($_GET['from'])   ? $_GET['from'] : addslashes($_LANG['self_site']);
        $from_ad   = !empty($_GET['ad_id']) ? intval($_GET['ad_id']) : 0;

        $_SESSION['from_ad'] = $from_ad; // 用户点击的广告ID
        $_SESSION['referer'] = stripslashes($site_name); // 用户来源

        unset($site_name);

        if (!defined('INGORE_VISIT_STATS'))
        {
            visit_stats();
        }
    }

    if (empty($_SESSION['user_id']))
    {
        if ($user->get_cookie())
        {
            /* 如果会员已经登录并且还没有获得会员的帐户余额、积分以及优惠券 */
            if ($_SESSION['user_id'] > 0)
            {
                update_user_info();
            }
        }
        else
        {
            $_SESSION['user_id']     = 0;
            $_SESSION['user_name']   = '';
            $_SESSION['email']       = '';
            $_SESSION['user_rank']   = 0;
            $_SESSION['discount']    = 1.00;
            if (!isset($_SESSION['login_fail']))
            {
                $_SESSION['login_fail'] = 0;
            }
        }
    }

    /* 设置推荐会员 */
    if (isset($_GET['u']))
    {
        set_affiliate();
    }

    /* session 不存在，检查cookie */
    if (!empty($_COOKIE['ECS']['user_id']) && !empty($_COOKIE['ECS']['password']))
    {
        // 找到了cookie, 验证cookie信息
        $sql = 'SELECT user_id, user_name, password ' .
                ' FROM ' .$ecs->table('users') .
                " WHERE user_id = '" . intval($_COOKIE['ECS']['user_id']) . "' AND password = '" .$_COOKIE['ECS']['password']. "'";

        $row = $db->GetRow($sql);

        if (!$row)
        {
            // 没有找到这个记录
           $time = time() - 3600;
           setcookie("ECS[user_id]",  '', $time, '/');
           setcookie("ECS[password]", '', $time, '/');
        }
        else
        {
            $_SESSION['user_id'] = $row['user_id'];
            $_SESSION['user_name'] = $row['user_name'];
            update_user_info();
        }
    }

    if (isset($smarty))
    {
        $smarty->assign('ecs_session', $_SESSION);
    }
}

一些会员信息的设置。这些都是公共的信息。
等等。

以上是init.php文件中的主要内容。

下面继续转战index.php中。

if ((DEBUG_MODE & 2) != 2)
{
    $smarty->caching = true;
}
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

$uachar = "/(nokia|sony|ericsson|mot|samsung|sgh|lg|philips|panasonic|alcatel|lenovo|cldc|midp|mobile)/i";

if(($ua == '' || preg_match($uachar, $ua))&& !strpos(strtolower($_SERVER['REQUEST_URI']),'wap'))
{
    $Loaction = 'mobile/';

    if (!empty($Loaction))
    {
        ecs_header("Location: $Loaction\n");

        exit;
    }

}

上述代码，大概就是为各大手机厂商进行设计的。收到上述信息，就跳转到手机商城页面。Ecshop专门为手机设计了相应的界面。功能还是PHP来实现的。

/*------------------------------------------------------ */
//-- Shopex系统地址转换
/*------------------------------------------------------ */
if (!empty($_GET['gOo']))
{
    if (!empty($_GET['gcat']))
    {
        /* 商品分类。*/
        $Loaction = 'category.php?id=' . $_GET['gcat'];
    }
    elseif (!empty($_GET['acat']))
    {
        /* 文章分类。*/
        $Loaction = 'article_cat.php?id=' . $_GET['acat'];
    }
    elseif (!empty($_GET['goodsid']))
    {
        /* 商品详情。*/
        $Loaction = 'goods.php?id=' . $_GET['goodsid'];
    }
    elseif (!empty($_GET['articleid']))
    {
        /* 文章详情。*/
        $Loaction = 'article.php?id=' . $_GET['articleid'];
    }

    if (!empty($Loaction))
    {
        ecs_header("Location: $Loaction\n");
        exit;
    }
}

这是跳转功能，收到这些请求，就会跳转到相应的界面。

    }

    $links = index_get_links();

    if (!empty($cat_recommend_res))

    }

    /* 页面中的动态内容 */
    assign_dynamic('index');
}

$smarty->display('index.dwt', $cache_id);

如果有缓存，会读取缓存中的信息，如果没有则重新执行一次查询，并用smarty将数据导入到视图界面。默认为themes目录下的default目录中的index.dwt文件。

}

最后的是一些查询函数，查询数据库中的信息。并展示出来。

通过smarty对数据进行分配。由此完成了页面的展示。

进行二次开发的时候，可以修改界面。注意缓存问题。可以修改逻辑层的信息。掌握了其中的脉络之后，就可以对症下药。

还是那句话，知道在哪里写代码，就是成功的一半了。
