第1步：在后台admin / templates / goods_info.htm中找到大概164行至173行修改以下代码  。

<tr>  <td class="label"><label for="is_promote">  <input type="checkbox" id="is_promote_switch" name="is_promote_switch" {if $goods.is_promote}checked="checked"{/if} onclick="handlePromote(this.checked);" /> 是否参加促销</label>  <select name="is_promote" id="is_promote">  <option value="" >请选择</option>  <option value="1" {if $goods.is_promote eq 1}selected="selected"{/if}>{$lang.lab_promote_price}</option>  <option value="2" {if $goods.is_promote eq 2}selected="selected"{/if}>限时价：</option>  <option value="3" {if $goods.is_promote eq 3}selected="selected"{/if}>秒杀价：</option>  </select>  </td>  <td id="promote_3">  <input type="text" id="promote_1" name="promote_price" value="{$goods.promote_price}" size="20" />  </td>  </tr>  <tr id="promote_4">  <td class="label" id="promote_5">{$lang.lab_promote_date}</td>  <td id="promote_6">  <input name="promote_start_date" type="text" id="promote_start_date" size="15" value='{$goods.promote_start_date}' readonly="readonly" /><input name="selbtn1" type="button" id="selbtn1" onclick="return showCalendar('promote_start_date', '%Y-%m-%d %H:%M','24', false, 'selbtn1');" value="{$lang.btn_select}" class="button"/> - <input name="promote_end_date" type="text" id="promote_end_date" size="15" value='{$goods.promote_end_date}' readonly="readonly" /><input name="selbtn2" type="button" id="selbtn2" onclick="return showCalendar('promote_end_date', '%Y-%m-%d %H:%M','24', false, 'selbtn2');" value="{$lang.btn_select}" class="button"/>  </td>  </tr>  。

并找到下面js代码中的onload = function()函数将里面的  。

handlePromote(document.forms['theForm'].elements['is_promote'].checked);  。

改为  。

handlePromote(document.forms['theForm'].elements['is_promote_switch'].checked);  。

第2步：把admin下的goods.php改一句话，注释部分为原先部分  。

//$is_promote = empty($promote_price) ? 0 : 1;  $is_promote = empty($promote_price) ? 0 : $_POST['is_promote'];  。

第3步：找到admin / includes / lib_goods.php里的goods_list函数，将switch条件里的  。

case 'is_promote':  $where .= " AND is_promote = 1 AND promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today'";  break;  。

改为  。

case 'is_promote':  $where .= " AND is_promote > 0 AND promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today'";  break;  。

否则在后台商品列表页搜索功能中的推荐的特价不能用  第4步：在includes / lib_goods.php中添加一个函数方法  。

/**  * 获得限时商品  *  * @access public  * @return array  */  function get_time_goods($cats = '')  {  $time = gmtime();  $order_type = $GLOBALS['_CFG']['recommend_order'];  /* 取得限时lbi的数量限制 */  $num = get_library_number("recommend_promotion");  $sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .  "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".  "promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, b.brand_name, " .  "g.is_best, g.is_new, g.is_hot, g.is_promote, RAND() AS rnd " .  'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' .  'LEFT JOIN ' . $GLOBALS['ecs']->table('brand') . ' AS b ON b.brand_id = g.brand_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 ' .  " AND g.is_promote = 2 AND promote_start_date <= '$time' AND promote_end_date >= '$time' ";  $sql .= $order_type == 0 ? ' ORDER BY g.sort_order, g.last_update DESC' : ' ORDER BY rnd';  $sql .= " LIMIT $num ";  $result = $GLOBALS['db']->getAll($sql);  $goods = array();  foreach ($result 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]['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'] = 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']);  /* 限时时间倒计时 */  $time = gmtime();  if ($time >= $row['promote_start_date'] && $time <= $row['promote_end_date'])  {  $goods[$idx]['gmt_end_time'] = local_date('M d, Y H:i:s',$row['promote_end_date']);  }  else  {  $goods[$idx]['gmt_end_time'] = 0;  }  }  return $goods;  }  。

在index.php中加一句  。

$smarty->assign('time_goods', get_time_goods()); // 限时商品  。

第5步：在library中新建一个time_limit.lbi，代码如下  。

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">  <!-- {if $time_goods} -->  <script >  var Tday = new Array();  var daysms = 24 * 60 * 60 * 1000  var hoursms = 60 * 60 * 1000  var Secondms = 60 * 1000  var microsecond = 1000  var DifferHour = -1  var DifferMinute = -1  var DifferSecond = -1  function clock(key)  {  var time = new Date()  var hour = time.getHours()  var minute = time.getMinutes()  var second = time.getSeconds()  var timevalue = ""+((hour > 12) ? hour-12:hour)  timevalue +=((minute < 10) ? ":0":":")+minute  timevalue +=((second < 10) ? ":0":":")+second  timevalue +=((hour >12 ) ? " PM":" AM")  var convertHour = DifferHour  var convertMinute = DifferMinute  var convertSecond = DifferSecond  var Diffms = Tday[key].getTime() - time.getTime()  DifferHour = Math.floor(Diffms / daysms)  Diffms -= DifferHour * daysms  DifferMinute = Math.floor(Diffms / hoursms)  Diffms -= DifferMinute * hoursms  DifferSecond = Math.floor(Diffms / Secondms)  Diffms -= DifferSecond * Secondms  var dSecs = Math.floor(Diffms / microsecond)  if(convertHour != DifferHour) a="<font color=red>"+DifferHour+"</font>天";  if(convertMinute != DifferMinute) b="<font color=red>"+DifferMinute+"</font>时";  if(convertSecond != DifferSecond) c="<font color=red>"+DifferSecond+"</font>分"  d="<font color=red>"+dSecs+"</font>秒"  if (DifferHour>0) {a=a}  else {a=''}  document.getElementById("leftTime"+key).innerHTML = a + b + c + d; //显示倒计时信息  }  </script>  <div id="time_limit">  <div id="time_top">  <div id="time_title"><a href="../search.php?intro=promotion" target="_blank">限时抢购</a></div>  <div id="time_btn">  <a class="prev" href="javascript:;"></a>  <a class="active" href="javascript:;"></a>  <!--{foreach from=$time_goods key=key item=goods name="promotion_foreach"}-->  {if ($key+1)%5==0}  {if count($time_goods)!=$key+1}  <a class="index" href="javascript:;"></a>  {/if}  {/if}  <!--{/foreach}-->  <a class="next" href="javascript:;"></a>  </div>  </div>  <div id="time_nr">  <ul>  <li>  <!--{foreach from=$time_goods key=key item=goods name="promotion_foreach"}-->  <div class="xsqg">  <div class="xsqg_top"><a href="{$goods.url}" target="_blank"><img src="{$goods.thumb}" width="170" height="155" alt="{$goods.name|escape:html}"/></a></div>  <div class="xsqg_cen"><a href="{$goods.url}" target="_blank" title="{$goods.name|escape:html}">{$goods.short_name|escape:html}</a></div>  <div class="xsqg_bot">  <div class="te">{$goods.promote_price}</div>  <div class="yuan">{$goods.market_price}</div>  <div class="remain_time"><font style="color:#666;">剩余</font> <font id="leftTime{$key}">{$lang.please_waiting}</font></div>  <script>  Tday[{$key}] = new Date("{$goods.gmt_end_time}");  window.setInterval(function(){clock({$key});}, 1000);  </script>  </div>  </div>  <!--{/foreach}-->  </li>  </ul>  </div>  </div>  <!-- {/if} -->  。
