通过二次开发可以实现ECSHOP首页调用指定分类下的品牌列表。
第一步:
打开根目录下的index.php
在最后面 ?> 前面加入以下代码:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

/*** 获得某个分类下的品牌 列表** @access public* @param int $cat* @return array*/function get_cat_brands($cat = 0, $app = ‘category‘){ $children = ($cat > 0) ? ‘ AND ‘ . get_children($cat) : ‘‘;$sql = "SELECT b.brand_id, b.brand_name, b.brand_logo, COUNT(g.goods_id) AS goods_num, IF(b.brand_logo > ‘‘, ‘1‘, ‘0‘) AS tag ". "FROM " . $GLOBALS[‘ecs‘]->table(‘brand‘) . "AS b, ". $GLOBALS[‘ecs‘]->table(‘goods‘) . " AS g "."WHERE g.brand_id = b.brand_id $children " . "GROUP BY b.brand_id HAVING goods_num > 0 ORDER BY tag DESC, b.sort_order ASC";$row = $GLOBALS[‘db‘]->getAll($sql); foreach ($row AS $key => $val) { $row[$key][‘url‘] = build_uri($app, array(‘cid‘ => $cat, ‘bid‘ => $val[‘brand_id‘]), $val[‘brand_name‘]); } return $row; } |
第二步:
在index.dwt 模板里使用以下代码调用:
|
1
2
3
|
<!--{foreach from=get_cat_brands($this->_var[‘cat‘][‘id‘]) item=brandCat}--><li><a href="{$brandCat.url}"><img src="data/brandlogo/{$brandCat.brand_logo}" title="{$brandCat.brand_name}" width="106" height="36"><span>{$brandCat.brand_name}</span></a></li><!--{/foreach}--> |
需要指定分类ID调用,只要把代码中的
|
1
|
$this->_var[‘cat‘][‘id‘] |
改成 ID号就行,比如:调用ID=1的分类
|
1
2
3
|
<!--{foreach from=get_cat_brands(1) item=brandCat}--><li><a href="{$brandCat.url}"><img src="data/brandlogo/{$brandCat.brand_logo}" title="{$brandCat.brand_name}" width="106" height="36"><span>{$brandCat.brand_name}</span></a></li><!--{/foreach}--> |
美中不足的是,无法指定调用多少条。
