ecshop 首页显示指定的商品

ecshop后台虽然在产品列表里面可以设置商品属于精品，新品，，热卖几个类型。但是很多时候，我们在首页不但要展示这些商品，我们还可能需要人为的展现某些特被推荐的产品。而且很灵活的在ecshop商品列表的后台控制和选择某些商品是否属于特推商品。ECSHOP来发中心（）告诉您，我们必须在ecshop商品数据库里面增加一字段is_index来控制。

1: 首先我们给ecshop商品表增加一个字段is_index

alter table ecs_goods add column is_index int(1) default 0;

2:在商品列表中增加以下内容admin/templates/goods_list.htm

<th><a href="javascript:listTable.sort(‘is_index’); ">首页推荐</th> <td align="center"><img src="images/{if $goods.is_index}yes{else}no{/if}.gif" onclick="listTable.toggle(this, ‘toggle_is_index’, {$goods.goods_id})" /></td>

3: admin/goods.php中增加以下内容。

elseif ($_REQUEST[‘act’] == ‘toggle_is_index’){ check_authz_json(‘goods_manage’); $goods_id = intval($_POST[‘id’]); $is_index = intval($_POST[‘val’]); if ($exc->edit("is_index = ‘$is_index’, last_update=" .gmtime(), $goods_id)) { clear_cache_files(); make_json_result($is_index); }}

4:前台通过以下函数来调用数据

function assign_is_index_goods( $num = 16){ $sql = ‘SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ‘ . "IFNULL(mp.user_price, g.shop_price * ‘$_SESSION[discount]’) AS shop_price, ". ‘g.promote_price, promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ‘ . "FROM " . $GLOBALS[‘ecs’]->table(‘goods’) . ‘ AS g ‘. "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 AND is_index =1 ‘; $order_rule = empty($order_rule) ? ‘ORDER BY g.sort_order, g.goods_id DESC’ : $order_rule; $sql .= $order_rule; if ($num > 0) { $sql .= ‘ LIMIT ‘ . $num; } $res = $GLOBALS[‘db’]->getAll($sql); $goods = array(); foreach ($res AS $idx => $row) { if ($row[‘promote_price’] > 0) { $promote_price = bargain_price($row[‘promote_price’], $row[‘promote_start_date’], $row[‘promote_end_date’]); $goods[$idx][‘promote_price’] = $promote_price > 0 ? price_format($promote_price) : ”; } else { $goods[$idx][‘promote_price’] = ”; } $goods[$idx][‘id’] = $row[‘goods_id’]; $goods[$idx][‘name’] = $row[‘goods_name’]; $goods[$idx][‘brief’] = $row[‘goods_brief’]; $goods[$idx][‘market_price’] = price_format($row[‘market_price’]); $goods[$idx][‘short_name’] = $GLOBALS[‘_CFG’][‘goods_name_length’] > 0 ? sub_str($row[‘goods_name’], $GLOBALS[‘_CFG’][‘goods_name_length’]) : $row[‘goods_name’]; $goods[$idx][‘shop_price’] = price_format($row[‘shop_price’]); $goods[$idx][‘thumb’] = get_image_path($row[‘goods_id’], $row[‘goods_thumb’], true); $goods[$idx][‘goods_img’] = get_image_path($row[‘goods_id’], $row[‘goods_img’]); $goods[$idx][‘url’] = build_uri(‘goods’, array(‘gid’ => $row[‘goods_id’]), $row[‘goods_name’]); } return $goods;}

以上就完成了ecshop 首页显示指定的商品
