ecshop首页调用指定分类下商品

所属栏目:EcShop 时间:2014-02-18 来源:网络 作者:不详 点击:

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.goods_id desc";   
   //goods_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:

$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:

$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:

<!--{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。
