发布信息的时候设置几天、几月之后过期
1、增加字段gqtime 类型选择日期 投稿表单替换html代码(增加字段时请留空)内容修改为 <select name="gqtime" id="gqtime"><option value="<?echo date("Y-m-d",strtotime("+7day")); ?><?=DoReqValue($tbname,'gqtime',stripSlashes($r[gqtime]))?>">7天后过期</option><option value="<?echo date("Y-m-d",strtotime("+1month")); ?><?=DoReqValue($tbname,'gqtime',stripSlashes($r[gqtime]))?>">一个月后过期</option><option value="<?echo date("Y-m-d",strtotime("+3month")); ?><?=DoReqValue($tbname,'gqtime',stripSlashes($r[gqtime]))?>">三个月后过期</option><option value="<?echo date("Y-m-d",strtotime("+6month")); ?><?=DoReqValue($tbname,'gqtime',stripSlashes($r[gqtime]))?>" selected>六个月后过期</option><option value="<?echo date("Y-m-d",strtotime("+20year")); ?><?=DoReqValue($tbname,'gqtime',stripSlashes($r[gqtime]))?>">长期有效</option></select>
2、e\class\connect.php //栏目链接,上面加入如下代码: //时间 $odate = round(((strtotime($r[gqtime])-strtotime(date('Y-m-d')))/86400),0); if ($odate>0) { $diffTime = ''; // } else if ($odate==0) { $diffTime = '今天到期 '; } else { $diffTime = '<span class="expire">已过期</span> '; } $listtemp = str_replace ('[!--diffTime--]', $diffTime, $listtemp); //栏目链接
3、列表页面标题前面加上[!--diffTime--],如<div>[!--diffTime--]<a href="[!--titleurl--]">[!--title--]</a></div>
4、内容页调用<script language="javascript" src="images/date.js"></script>
在需要显示的地方,输入<script>check_tdate('[!--gqtime--]')</script>
5、date.js代码如下: // JavaScript Document function check_tdate(odate){ var checkArray= new Array() ; //nowArray = odate.split(" "); checkArray = odate.split("-"); checkDate = new Date(checkArray[0],checkArray[1],checkArray[2]); var nowTime = new Date();// 现在时间 var the_year = nowTime.getYear(); var the_month = nowTime.getMonth() + 1; var the_day = nowTime.getDate(); nowTime = new Date(the_year,the_month,the_day); var thesecond = 24 * 60 * 60 *1000 ; var diffTime = (nowTime - checkDate)/thesecond;//计算天数 if (diffTime>0) { myreturn ="<div style='position:absolute;z-index:100;margin-left:150px;'><img src=../../../images/guoqi.gif></div>"; } else if (diffTime==0) { myreturn = ''; } else { diffTime=0-diffTime; myreturn = ''; } //alert(myreturn); document.write(''+myreturn+'') }
