	$pubdate = $dsql->GetOne("select pubdate from article where writer ='".$writer."' order by id desc limit 1");	if((time()-$pubdate['pubdate'])<(3600*24)){		ShowMsg("对不起,一个会员每天只能发一篇文章!","-1","0",5000);		exit;	}


以上判断一个会员在一天内只能提交一篇文档,想修改成可以提交3篇,应该怎么做?


回复讨论(解决方案)

$pubdate = $dsql->GetOne("select pubdate,writer,count(pubdate) as total from article where writer ='".$writer."' and pubdate if($pubdate['total'])==3){
   ShowMsg("对不起,一个会员每天只能发一篇文章!","-1","0",5000);
   exit;
}


mysql查询一天内提交的文章数,如果>=3不能提交

$pubdate = $dsql->GetOne("select pubdate,writer,count(pubdate) as total from article where writer ='".$writer."' and pubdate if($pubdate['total'])==3){
   ShowMsg("对不起,一个会员每天只能发一篇文章!","-1","0",5000);
   exit;
}


mysql查询一天内提交的文章数,如果>=3不能提交

mysql跑不起来。跪求检查一下。
另外:if($pubdate['total'])==3)应该是if(($pubdate['total'])==3)这样吧?
数据库字段:
数据库名称(article)
会员名称(writer)
发布时间(pubdate)

原代码改为

$n = 1; //你指定的篇数$pubdate = $dsql->GetOne("select count(*) as cnt from article where FROM_UNIXTIME(pubdate,'%Y%m%d')=DATE_FORMAT(now(),'%Y%m%d') and writer ='".$writer."' order by id desc limit 1");if($pubdate['pubdate'] > $n){    ShowMsg("对不起,一个会员每天只能发 $n 篇文章!","-1","0",5000);    exit;}

还是版主给力,学习了
