第一步：在goods表格增加一個字段 is_bonus 類型 tinyint 默認爲1 (1是可以使用紅包)
第二步：修改後臺模板頁 goods_info.htm
<tr id=”alone_sale_1″><td id=”alone_sale_2″>{$lang.lab_is_on_sale}</td><td id=”alone_sale_3″><input type=”checkbox” name=”is_on_sale” value=”1″ {if $goods.is_on_sale}checked=”checked”{/if} /> {$lang.on_sale_desc}</td></tr><tr id=”alone_sale_1″><td id=”alone_sale_2″>紅包使用</td><td id=”alone_sale_3″><input type=”checkbox” name=”is_bonus” value=”1″ {if $goods.is_bonus}checked=”checked”{/if} /> 打勾表示允許用使用紅包，否則不允許使用。</td></tr><tr><td>{$lang.lab_is_alone_sale}</td><td><input type=”checkbox” name=”is_alone_sale” value=”1″ {if $goods.is_alone_sale}checked=”checked”{/if} /> {$lang.alone_sale}</td></tr>
<tr id=”alone_sale_1″> <td id=”alone_sale_2″>{$lang.lab_is_on_sale}</td> <td id=”alone_sale_3″><input type=”checkbox” name=”is_on_sale” value=”1″ {if $goods.is_on_sale}checked=”checked”{/if} /> {$lang.on_sale_desc}</td> </tr>
<tr id=”alone_sale_1″> <td id=”alone_sale_2″>紅包使用</td> <td id=”alone_sale_3″><input type=”checkbox” name=”is_bonus” value=”1″ {if $goods.is_bonus}checked=”checked”{/if} /> 打勾表示允許用使用紅包，否則不允許使用。</td> </tr>
<tr> <td>{$lang.lab_is_alone_sale}</td> <td><input type=”checkbox” name=”is_alone_sale” value=”1″ {if $goods.is_alone_sale}checked=”checked”{/if} /> {$lang.alone_sale}</td> </tr>
這個大概在230行左右
*注：我沒有修改語言包，如果你需要可以先去修改語言包，然後這裏調言（呵呵）
第三步：修改後臺goods.php文件
在添加新商品 編輯商品 下面修改
158行和230行左右的 $goods數組加下下面紅色的部分(我這裏默認是可以使用紅包的)
$goods = array(
‘goods_id’ => 0,
‘goods_desc’ => ”,
‘cat_id’ => $last_choose[0],
‘brand_id’ => $last_choose[1],
‘is_on_sale’ => ’1′,
‘is_bonus’ => ’1′,
‘is_alone_sale’ => ’1′,
‘is_shipping’ => ’0′,
‘other_cat’ => array(), // 擴展分類
‘goods_type’ => 0, // 商品類型
‘shop_price’ => 0,
‘promote_price’ => 0,
‘market_price’ => 0,
‘integral’ => 0,
‘goods_number’ => $_CFG['default_storage'],
‘warn_number’ => 1,
‘promote_start_date’ => local_date(‘Y-m-d’),
‘promote_end_date’ => local_date(‘Y-m-d’, local_strtotime(‘+1 month’)),
‘goods_weight’ => 0,
‘give_integral’ => -1,
‘rank_integral’ => -1
);
插入和修改部份修改的代碼:
805行
$is_on_sale = isset($_POST['is_on_sale']) ? 1 : 0;
$is_bonus = isset($_POST['is_bonus']) ? 1 : 0;
$is_alone_sale = isset($_POST['is_alone_sale']) ? 1 : 0;
/* 入庫 */
if ($is_insert)
{
if ($code == ”)
{
$sql = “INSERT INTO ” . $ecs->table(‘goods’) . ” (goods_name, goods_name_style, goods_sn, ” .

“‘$promote_start_date’, ‘$promote_end_date’, ‘$goods_img’, ‘$goods_thumb’, ‘$original_img’, “.
“‘$_POST[keywords]‘, ‘$_POST[goods_brief]‘, ‘$_POST[seller_note]‘, ‘$goods_weight’, ‘$goods_number’,”.
” ‘$warn_number’, ‘$_POST[integral]‘, ‘$give_integral’, ‘$is_best’, ‘$is_new’, ‘$is_hot’, ‘$is_on_sale’,‘$is_bonus’,’$is_alone_sale’, $is_shipping, “.
” ‘$_POST[goods_desc]‘, ‘” . gmtime() . “‘, ‘”. gmtime() .”‘, ‘$goods_type’, ‘$rank_integral’, ‘$suppliers_id’)”;
}
else
{
$sql = “INSERT INTO ” . $ecs->table(‘goods’) . ” (goods_name, goods_name_style, goods_sn, ” .

” ‘$_POST[goods_desc]‘, ‘” . gmtime() . “‘, ‘”. gmtime() .”‘, ‘$goods_type’, ‘$code’, ‘$rank_integral’)”;
}
}
901行：
$sql .= “keywords = ‘$_POST[keywords]‘, ” .
“goods_brief = ‘$_POST[goods_brief]‘, ” .
“seller_note = ‘$_POST[seller_note]‘, ” .
“goods_weight = ‘$goods_weight’,” .
“goods_number = ‘$goods_number’, ” .
“warn_number = ‘$warn_number’, ” .
“integral = ‘$_POST[integral]‘, ” .
“give_integral = ‘$give_integral’, ” .

“last_update = ‘”. gmtime() .”‘, “.
“goods_type = ‘$goods_type’ ” .
“WHERE goods_id = ‘$_REQUEST[goods_id]‘ LIMIT 1″;
第四步：修改後臺模板頁goods_list.htm
25行：
<th><a href=”javascript:listTable.sort(‘is_hot’); “>{$lang.is_hot}</a>{$sort_is_hot}</th>
<th><a href=”javascript:listTable.sort(‘is_bonus’); “>紅包</a>{$sort_is_bonus}</th>
<th><a href=”javascript:listTable.sort(‘sort_order’); “>{$lang.sort_order}</a>{$sort_sort_order}</th>
47行：
<td align=”center”><img src=”images/{if $goods.is_hot}yes{else}no{/if}.gif” οnclick=”listTable.toggle(this, ‘toggle_hot’, {$goods.goods_id})” /></td>
<td align=”center”><img src=”images/{if $goods.is_bonus}yes{else}no{/if}.gif” οnclick=”listTable.toggle(this, ‘toggle_bonus’, {$goods.goods_id})” /></td>
<td align=”center”><span οnclick=”listTable.edit(this, ‘edit_sort_order’, {$goods.goods_id})”>{$goods.sort_order}</span></td>
98行：
<option value=”not_hot”>{$lang.not_hot}</option>
<option value=”bonus”>使用紅包</option>
<option value=”not_bonus”>取消紅包使用</option>
<option value=”move_to”>{$lang.move_to}</option>
第五步：修改後臺goods.php
在1500行左右加上
/*—————————————————— */
//– 修改紅包使用狀態
/*—————————————————— */
elseif ($_REQUEST['act'] == ‘toggle_bonus’)
{
check_authz_json(‘goods_manage’);
$goods_id = intval($_POST['id']);
$is_bonus = intval($_POST['val']);
if ($exc->edit(“is_bonus = ‘$is_bonus’, last_update=” .gmtime(), $goods_id))
{
clear_cache_files();
make_json_result($is_bonus);
}
}
/*—————————————————— */
//– 修改商品排序
/*—————————————————— */
到此後臺功能已經修改完成
再修改前臺：
首頁在tb_cart表中加一個字段 is_bonus 類型 tinyint 默認爲1 (1是可以使用紅包)
找到includes/lib_order.php 中的 function addto_cart
1022行：
$sql = “SELECT g.goods_name, g.goods_sn, g.is_on_sale, g.is_real,g.is_bonus, “.
“g.market_price, g.shop_price AS org_price, g.promote_price, g.promote_start_date, “.
“g.promote_end_date, g.goods_weight, g.integral, g.extension_code, “.
“g.goods_number, g.is_alone_sale, g.is_shipping,”.
“IFNULL(mp.user_price, g.shop_price * ‘$_SESSION[discount]‘) AS shop_price “.
” 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.goods_id = ‘$goods_id’” .
” AND g.is_delete = 0″;
1117行：
/* 初始化要插入購物車的基本件數據 */
$parent = array(
‘user_id’ => $_SESSION['user_id'],
‘session_id’ => SESS_ID,
‘goods_id’ => $goods_id,
‘goods_sn’ => addslashes($goods['goods_sn']),
‘product_id’ => $product_info['product_id'],
‘goods_name’ => addslashes($goods['goods_name']),
‘market_price’ => $goods['market_price'],
‘goods_attr’ => addslashes($goods_attr),
‘goods_attr_id’ => $goods_attr_id,
‘is_real’ => $goods['is_real'],
‘extension_code’=> $goods['extension_code'],
‘is_gift’ => 0,
‘is_bonus’ => $goods['is_bonus'],
‘is_shipping’ => $goods['is_shipping'],
‘rec_type’ => CART_GENERAL_GOODS
);
再修改：function order_fee 大概在545行
/* 商品總價 */
foreach ($goods AS $val)
{
/* 統計實體商品的個數 */
if ($val['is_real'])
{
$total['real_goods_count']++;
}
if($val['is_bonus'])
{
$total['goods_bonus_price'] += $val['goods_price'] * $val['goods_number'];
}
$total['goods_price'] += $val['goods_price'] * $val['goods_number'];
$total['market_price'] += $val['market_price'] * $val['goods_number'];
}
第六步：修改後臺商品列表顯示頁代碼
找到後臺includes/lib_goods.php 中的 function goods_list
$sql = “SELECT goods_id, goods_name, goods_type, goods_sn, shop_price, is_on_sale, is_best, is_new, is_hot,is_bonus, sort_order, goods_number, click_count,integral, ” .
” (promote_price > 0 AND promote_start_date <= ‘$today’ AND promote_end_date >= ‘$today’) AS is_promote “.
” FROM ” . $GLOBALS['ecs']->table(‘goods’) . ” AS g WHERE is_delete=’$is_delete’ $where” .
” ORDER BY $filter[sort_by] $filter[sort_order] “.
” LIMIT ” . $filter['start'] . “,$filter[page_size]“;
最後一步就是修改flow.php
大概在686行
/* 如果使用紅包，取得用戶可以使用的紅包及用戶選擇的紅包 */
if ((!isset($_CFG['use_bonus']) || $_CFG['use_bonus'] == ’1′)
&& ($flow_type != CART_GROUP_BUY_GOODS && $flow_type != CART_EXCHANGE_GOODS))
{
// 取得用戶可用紅包
$user_bonus = user_bonus($_SESSION['user_id'], $total['goods_bonus_price']);
此功能有個缺陷就是指定商品不能用紅包，所有的紅包都不能用了
