这篇文章主要介绍了ecshop中如何添加限时抢购功能，在页面中可以看到一个倒计时，下面是详细的实现步骤，适合所有新手朋友们。

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

代码如下:

<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

代码如下:

handlepromote(document.forms['theform'].elements['is_promote'].checked);

改为

代码如下:

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

代码如下:

//$is_promote = empty($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函数，将switch条件里的

代码如下:

case 'is_promote':

$where .= and is_promote = 1 and promote_price > 0 and promote_start_date <= '$today' and promote_end_date >= '$today';

break;

改为

代码如下:

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

代码如下:

/**

* 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

代码如下:

$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

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

}
