| 范文 | 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 $time_goods} --> <script > var tday = new array(); var daysms = 24 * 60 * 60 * 1000 var hoursms = 60 * 60 * 1000 var secondms = 60 * 1000 var microsecond = 1000 var differhour = -1 var differminute = -1 var differsecond = -1 function clock(key) { var time = new date() var hour = time.gethours() var minute = time.getminutes() var second = time.getseconds() var timevalue = +((hour > 12) ? hour-12:hour) timevalue +=((minute < 10) ? :0::)+minute timevalue +=((second < 10) ? :0::)+second timevalue +=((hour >12 ) ? pm: am) var converthour = differhour var convertminute = differminute var convertsecond = differsecond var diffms = tday[key].gettime() - time.gettime() differhour = math.floor(diffms / daysms) diffms -= differhour * daysms differminute = math.floor(diffms / hoursms) diffms -= differminute * hoursms differsecond = math.floor(diffms / secondms) diffms -= differsecond * secondms var dsecs = math.floor(diffms / microsecond) if(converthour != differhour) a=<font color=red>+differhour+</font>天; if(convertminute != differminute) b=<font color=red>+differminute+</font>时; if(convertsecond != differsecond) c=<font color=red>+differsecond+</font>分 d=<font color=red>+dsecs+</font>秒 if (differhour>0) {a=a} else {a=''} document.getelementbyid(lefttime+key).innerhtml = a + b + c + d; //显示倒计时信息 } </script> <div id=time_limit> <div id=time_top> <div id=time_title><a href=../search.php?intro=promotion target=_blank>限时抢购</a></div> <div id=time_btn> <a class=prev href=javascript:;></a> <a class=active href=javascript:;></a> <!--{foreach from=$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} --> |
