ecshop首页调用指定分类下商品
ECSHOP默认只能在后台模板设置中设置首页调用分类下商品，比较死板。
为了更好的设计调用分类商品，可使用以下方法自定义调用：
第一步：
找到打开 /includes/lib_goods.php
在末尾 ?> 前加入以下代码：

function get_cat_id_goods_index_list($cat_id = '', $num = '') //申明$cat_id，$num函数{$sql = 'Select g.goods_id, g.cat_id,c.parent_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' ."IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, "."promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, " ."g.is_best, g.is_new, g.is_hot, g.is_promote " .'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' .'LEFT JOIN ' . $GLOBALS['ecs']->table('category') . ' AS c ON c.cat_id = g.cat_id ' ."LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp "."ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' "."Where g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 ".$sql .= " AND (c.parent_id =" . $cat_id. " OR g.cat_id = " . $cat_id ." OR g.cat_id ". db_create_in(array_unique(array_merge(array($cat_id), array_keys(cat_list($cat_id, 0, false))))) .")" . "order by g.cat_id desc"; //cat_id降序排列$sql .= " LIMIT $num";$res = $GLOBALS['db']->getAll($sql);$goods = array();foreach ($res AS $idx => $row){$goods[$idx]['id'] = $row['article_id'];$goods[$idx]['id'] = $row['goods_id'];$goods[$idx]['name'] = $row['goods_name'];$goods[$idx]['brief'] = $row['goods_brief'];$goods[$idx]['brand_name'] = $row['brand_name'];$goods[$idx]['goods_style_name'] = add_style($row['goods_name'],$row['goods_name_style']);$goods[$idx]['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ?sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];$goods[$idx]['short_style_name'] = add_style($goods[$idx]['short_name'],$row['goods_name_style']);$goods[$idx]['market_price'] = price_format($row['market_price']);$goods[$idx]['shop_price'] = price_format($row['shop_price']);$goods[$idx]['thumb'] = empty($row['goods_thumb']) ? $GLOBALS['_CFG']['no_picture'] : $row['goods_thumb'];$goods[$idx]['goods_img'] = empty($row['goods_img']) ? $GLOBALS['_CFG']['no_picture'] : $row['goods_img'];$goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);}return $goods;} |
第二步：
打开根目录下的 index.php
查找：
|
1
|
$smarty->assign('shop_notice', $_CFG['shop_notice']); // 商店公告 |
在这段代码后面，也就是下一行添加以下代码：
|
1
|
$smarty->assign('cat_id1_index_goods', get_cat_id_goods_index_list(1,8)); //首页调用分类1下的8个商品 |
第三步：
打开/themes/default/index.dwt
在需要的地方添加以下代码：
|
1
2
3
4
5
6
7
8
|
<!--{foreach from=$cat_id1_index_goods item=goods}--><a class="first" href="{$goods.url}" target="_blank"><img title="{$goods.name|escape:html}" alt="{$goods.name|escape:html}" width="220" height="220" src="{$goods.goods_img}"/><p class="title" title="{$goods.name|escape:html}"> {$goods.name|escape:html} </p><p class="price"> <span class="label">原价:</span><del>{$goods.market_price}</del></p><p class="price qz-price"><span class="label">现价:</span><em>{$goods.shop_price}</em></p></a><!-- { /foreach }--> |
如果首页需要重复多次调用，只需重复第二步代码即可。
