這篇文章主要介紹了ecshop中如何添加限時搶購功能，在頁面中可以看到一個倒計時，下面是詳細(xì)的實現(xiàn)步驟，適合所有新手朋友們。
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
代碼如下:
<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="{$lang.btn_select}" class="button"/>
</td>
</tr>
并找到下面js代碼中的onload = function()函數(shù)將里面的
代碼如下:
handlePromote(document.forms['theForm'].elements['is_promote'].checked);
改為
代碼如下:
handlePromote(document.forms['theForm'].elements['is_promote_switch'].checked);
第2步：把a(bǔ)dmin下的goods.php改一句話，注釋部分為原先部分
代碼如下:
//$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(shù)，將switch條件里的
代碼如下:
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
代碼如下:
case 'is_promote':
$where .= " AND is_promote > 0 AND promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today'";
break;
否則在后臺商品列表頁搜索功能中的推薦的特價不能用
第4步：在includes / lib_goods.php中添加一個函數(shù)方法
代碼如下:
/**
* 獲得限時商品
*
* @access public
* @return array
*/
function get_time_goods($cats = '')
{
$time = gmtime();
$order_type = $GLOBALS['_CFG']['recommend_order'];
/* 取得限時lbi的數(shù)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
代碼如下:
$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
代碼如下:
<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>時";
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; //顯示倒計時信息
}
