我们会看到很多的网站可以看到有分类并且可以显示当前分类有多少商品数量了,下面我来给大家介绍实现方法.
非常简单的改动
1、includes/lib_goods.php下,找到这两个函数改成我这样就行,代码如下:
-
function get_categories_tree($cat_id = 0)
-
function get_child_tree($tree_id = 0)
-
-
-
-
-
-
-
-
-
function get_categories_tree($cat_id = 0)
-
{
-
if ($cat_id > 0)
-
{
-
$sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'";
-
$parent_id = $GLOBALS['db']->getOne($sql);
-
}
-
else
-
{
-
$parent_id = 0;
-
}
-
-
-
-
-
-
-
$sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$parent_id' AND is_show = 1 ";
-
if ($GLOBALS['db']->getOne($sql) || $parent_id == 0)
-
{
-
-
$sql = 'SELECT cat_id,cat_name ,parent_id,is_show ' .
-
'FROM ' . $GLOBALS['ecs']->table('category') .
-
"WHERE parent_id = '$parent_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";
-
-
$res = $GLOBALS['db']->getAll($sql);
-
-
foreach ($res AS $row)
-
{
-
if ($row['is_show'])
-
{
-
-
$children = get_children($row['cat_id']);
-
$sql = 'SELECT count(*)' . "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.
-
'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
-
'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';
-
$cat_goods_num=$GLOBALS['db']->getOne($sql);
-
$cat_arr[$row['cat_id']]['goods_num'] = $cat_goods_num == '' ? 0 : $cat_goods_num;
-
-
$cat_arr[$row['cat_id']]['id'] = $row['cat_id'];
-
$cat_arr[$row['cat_id']]['name'] = $row['cat_name'];
-
$cat_arr[$row['cat_id']]['url'] = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
-
-
if (isset($row['cat_id']) != NULL)
-
{
-
$cat_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']);
-
}
-
}
-
}
-
}
-
if(isset($cat_arr))
-
{
-
return $cat_arr;
-
}
-
}
-
-
function get_child_tree($tree_id = 0)
-
{
-
$three_arr = array();
-
$sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$tree_id' AND is_show = 1 ";
-
if ($GLOBALS['db']->getOne($sql) || $tree_id == 0)
-
{
-
$child_sql = 'SELECT cat_id, cat_name, parent_id, is_show ' .
-
'FROM ' . $GLOBALS['ecs']->table('category') .
-
"WHERE parent_id = '$tree_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";
-
$res = $GLOBALS['db']->getAll($child_sql);
-
foreach ($res AS $row)
-
{
-
-
$children = get_children($row['cat_id']);
-
$sql = 'SELECT count(*)' . "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.
-
'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
-
'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';
-
$cat_goods_num=$GLOBALS['db']->getOne($sql);
-
$three_arr[$row['cat_id']]['goods_num'] = $cat_goods_num == '' ? 0 : $cat_goods_num;
-
-
if ($row['is_show'])
-
-
$three_arr[$row['cat_id']]['id'] = $row['cat_id'];
-
$three_arr[$row['cat_id']]['name'] = $row['cat_name'];
-
$three_arr[$row['cat_id']]['url'] = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
-
-
if (isset($row['cat_id']) != NULL)
-
{
-
$three_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']);
-
-
}
-
}
-
}
-
return $three_arr;

}
library/group_buy.lbi
注意这里:原版的lefttime.js是定义的单个ID
<font id="leftTime" class="f1"> 这里循环了,ID重复一定报错,这里怎么解决呢?你可以自己从JS文件夹里新复制一个lefttime.js这里我命名为:lefttime1.js;调用如下代码:
-
<script type="text/javascript" src="js/lefttime1.js"></script>
-
-
-
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
-
<script type="text/javascript" src="js/lefttime.js"></script>
-
-
-
<!-- {if $group_buy_goods} -->
-
<div class="box" style="border:1px solid #e2e2e2; width:198px;">
-
<h3><span>{$lang.group_buy_goods}</span></h3>
-
<div class="box_1" style="border:none;">
-
<div class="boxCenterList clearfix">
-
<!--{foreach from=$group_buy_goods item=goods}-->
-
<ul class="clearfix" style="position:relative;">
-
<li class="goodsimg" style="width:190px; height:190px; margin:0px;"><a style=" margin:0px;width:190px; height:190px;" href="{$goods.url}"><img src="{$goods.thumb}" alt="{$goods.goods_name|escape:html}" class="goodsimg" style=" margin:0;width:190px; height:190px;" /></a></li>

-
<li style="width:100%;"><font class="shop_s">{$goods.last_price}</font></li>
-
<div class="index_group">售出 <strong>{$goods.vn}</strong> 件</div>
-
剩余时间:<span id="leftTime">结束时间:{$goods.gmt_end_date}</span>

</ul>
