ecshop的一些东西，来看看

\includes\lib_commom.php =>公用函数库

\includes\lib_main.php =>前台公用函数库

\includes\lib_init.php =>初始化，供/index.php调用

\includes\lib_insert.php =>动态内容函数库 模板{insert name='ads' id=$ads_id num=$ads_num} 所调用的函数即是 function insert_ads

\includes\cls_template.php =>含有格式化函数 模板{$goods.name|escape:html}

\includes\inc_constant.php=>常量定义

【foreach的使用方法】

1:foreach使用规则，他有以下几个参数 from ,item name iteration index

2:如何使用foreach循环

　　如果php要传递一个数组（如：$array）给ecshop的smarty模板．那么我们将通过from=$array 来接受，写法是{foreach from = $array item = item}

3:
     ecshop中smarty的下标如何表示，请看下面的例子：
     {foreach from = $array item = item name=name} 
     {$smarty.foreach.name.iteration}
     {/foreach}

这里的iteration就是从1开始的下标，
     如果要从０开始的下标，应该使用{$smarty.foreach.name.index}

4:如何判断是否是foreach循环的开始和结束，最后一个元素．

{if $smarty.foreach.last}表示循环的最后一个元素．{if $smarty.freach.first}表示循环的开始．

5:如何使用双重循环．

举例如下：

{foreach from = $test item =item}

{foreach from=$item.children item=child}
 {$child.name}
 {/foreach}
{/foreach}

6:from传参形式

模板：<!-- {foreach name=nav_middle_list from=$navigator_list.middle item=nav} -->

smarty：$smarty->assign('navigator_list',        get_navigator($ctype, $catlist));

模板里引用的from值[middle]就是参数

【smarty->display函数的用法】

根据id显示不同页面：

http://127.0.0.13/article_cat.php?id=6

http://127.0.0.13/article_cat.php?id=7

if($cat_id==6){
    $smarty->display('article_cat_xgzn.dwt', $cache_id);
}elseif($cat_id==7){
    $smarty->display('article_cat_boke.dwt', $cache_id);
}else{
    $smarty->display('article_cat.dwt', $cache_id);
}

【小技巧】

转换UNIX时间戳: $goods[$idx]['sj_date']   = date($GLOBALS['_CFG']['date_format'], $row['sj_date']);

文本格式化：{$cat_goods.name|escape:html}

字符串截取：{$brand.brand_desc|truncate:11}、{$article.short_title|truncate:15:"...":true}

处理换行：{$title|nl2br}将php中的换行符变成HTML中的<br>

过滤HTML标签：{$title|strip_tags}

goods.dwt大图：{$pictures.0.img_url}

【后台模板二次开发】

1.增加商品属性：

a.向数据表(*_goods)添加字段(sj_date)。

b.向模板(admin/templates/goods_info.htm)添加

c.向后台提交数据处理函数添加字段进行入库(admin/goods.php)。

d.前台显示函数进行处理(includes\lib_goods.php)。

2.设置后台模板[商品分类页模板]增加新品上架：

a.向数据表(*_template)新增记录

b.向/admin/includes/lib_template.php添加新增的库 （3代表可编辑数量）

3.在模板中多维数组的遍历：

a.数组原型：print_r打印

b.模板foreach遍历
