最近做了个论坛,就是不显示数据库中的内容，只显示主题的数量,不知道是哪里出错了，显示 部分的代码如下,我怀疑是红色部分写错了，数据库是forum里面的数据表是article和board <?php $sql="select * from article where type='$type' and replyx = 0 order by newdate desc limit $offset,20"; $result=mysql_db_query("forum",$sql); $num=mysql_num_rows($result); if($num != 0) { while($r=mysql_fetch_array($result)) { $fid=$r["id"]; $ftitle=$r["title"]; $fwriter=$r["writer"]; $fdate=$r["newdate"]; $fm=$r["mark"]; $frenum=$r["renum"]; $sql="select id from article where reply='$fid'"; $result=mysql_db_query("forum",$sql); $ffnum=mysql_num_rows($result); echo""; echo"$ffnum\n"; echo ""; echo ""; echo "$ftitle\n"; echo ""; if($fm == 1) { echo "m  "; } echo $frenum; echo "\n"; echo ""; echo " $fwriter\n"; echo ""; echo "$fdate\n"; } } ?>
