ecshop如何在首页显示指定商品
ecshop 首页默认的是有精品、新品、热卖这几个版块,当然也可以在后台进行这几个版块显示的商品,但是现在有这样一个问题,如果我不想要首页显示这些商品呢,我只想更人性化一些,人为的显示一些固定的商品,而且在后台又可以进行控制某些商品是否是特推的商品,这样的功能也很容易实现,只是 ecshop 二次开发的小技巧而已,下面夏日博客就来把方法分享一下。
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 ';
- $order_rule = emptyempty($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
