ecshop中foreach循环如何指定循环某个分类的产品

是单个的

Answer 1

1、在系统目录文件找到includes/lib_goods.php 这个文件打开在此页最底部加入以下函数代码：
/**
* 首页获取指定分类产品
*
* @access public
* @param string $cat_id53_best_goods
* @param array $cat_id53_best_goods
* @return array
*/
function get_cat_id_goods_list($cat_id = '', $num = '') {
$sql = 'Select g.goods_id, g.cat_id,c.parent_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_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 ) ) ) ) ) . ")";
$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;
}
2、打开系统根目录下index.php文件加入如下代码,如果要在别的页面调用加到别的页面：
$smarty->assign('cat_id_goods_list_86', get_cat_id_goods_list(86,9));
// 指定商品调用
//其中86指的调用的栏目ID，9指的是调用商品的数量
3、
在首页模版中调用即可，如下:
<!--{foreach from=$cat_id_goods_list_86 item=goods}-->
<li> 　 <a href="{$goods.url}" target="_blank"> <img src="{$goods.thumb}" alt="{$goods.name|escape:html}" /></a> <span class="a_title"> <a href="{$goods.url}" title="{$goods.name|escape:html}" target="_blank"> {$goods.short_style_name}</a> </span> <div style="text-indent: 5px;">市场价 <span class="del">{$goods.market_price}</span></div> <div style="text-indent: 5px;"><span class="red">售 价 {$goods.shop_price}</span></div></li>
<!--{/foreach}-->

追问

不能用

Answer 2

循环分类商品是goods_list.lbi库文件，但是所有的分类都会循环出来，不过每个分类页面只会显示该分类下的产品
