ecshop二次开发秒杀、限时折扣、清仓等功能

 限时抢购，秒杀商品的二次开发

1，先在后台admin/templates 中找goods_info.htm文件到促销部分，改为一个下拉列表的分别是促销，限时，秒杀，值分别是1，2，3
这样，代码如下：

<!--                  限时抢购开始 liangfang edit-->          <tr>            <td class="label"><label for="is_promote">                        <input type="checkbox" id="is_promote_switch" name="is_promote_switch" value="1" {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="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><!--                  限时抢购结束-->       

 

其中对时间选择框进行了重新设置为显示小时和分钟。
2，把admin下的goods.php 改一句话,注释部分是原先的代码

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

3、把下面的方法复制到你需要调用的页面：(方法中的sql条件WHERE is_promote = '2'是控制调用促销/限时/秒杀的)
