ecshop中的搶購插件，我想很多朋友都非常的喜歡，也想要得到它去開發，但是問題就在于這，我們需要怎么操作才能讓這個限時搶購插件在前端顯示呢？在這里我給大家說下，順便把代碼放在下面。

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

<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);" /> 是否參加促銷</label>
<select name="is_promote" id="is_promote">
<option value="" >請選擇</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}>限時價：</option>
<option value="3" {if $goods.is_promote eq 3}selected="selected"{/if}>秒殺價：</option>
</select>
</td>
<td id="promote_3">
<input type="text" id="promote_1" name="promote_price" value="{$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代碼中的onload = function()函數將里面的

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

改為

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

第2步：把admin下的goods.php改一句話，注釋部分為原先部分

//$is_promote = empty($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函數，將switch條件里的

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

改為

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

否則在后臺商品列表頁搜索功能中的推薦的特價不能用

第4步：在includes / lib_goods.php中添加一個函數方法

/**
* 獲得限時商品
*
* @access public
* @return array
*/
function get_time_goods($cats = '')
{
$time = gmtime();
$order_type = $GLOBALS['_CFG']['recommend_order'];
/* 取得限時lbi的數量限制 */
$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']);
/* 限時時間倒計時 */
$time = gmtime();
if ($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()); // 限時商品

第5步：在library中新建一個time_limit.lbi，代碼如下
