dede联动菜单无法添加二级选择

dede联动菜单是一个非常实用的功能，然而dedeCMS直接安装后，添加到联动三级菜单以后，再插入二级选择会自动生成三级选择，以下方法解决此bug。

一、找到：dede/stepselect_main.php文件将以下替换源文件215行的对应代码

else if($action=='addenum_save') { if(empty($ename) || empty($egroup)) { Showmsg("类别名称或组名称不能为空！","-1"); exit(); } if($issign == 1 || $topvalue == 0) { $enames = explode(',', $ename); foreach($enames as $ename) { $arr = $dsql->GetOne("SELECT * FROM `dede_sys_enum` WHERE egroup='$egroup' AND (evalue MOD 500)=0 ORDER BY disorder DESC "); if(!is_array($arr)) $disorder = $evalue = ($issign==1 ? 1 : 500); else $disorder = $evalue = $arr['disorder'] + ($issign==1 ? 1 : 500); $dsql->ExecuteNoneQuery("INSERT INTO `dede_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`) VALUES('$ename','$evalue','$egroup','$disorder','$issign'); "); } WriteEnumsCache($egroup); ShowMsg("成功添加枚举分类！".$dsql->GetError(), $ENV_GOBACK_URL); exit(); } else if ($issign == 3 && $topvalue != 0) { $minid = $topvalue; $maxnum = 500; // 三级子类最多500个 $enames = explode(',', $ename); foreach ($enames as $ename) { $arr = $dsql->GetOne("SELECT * FROM `dede_sys_enum` WHERE egroup='$egroup' AND evalue LIKE '$topvalue.%%%' ORDER BY evalue DESC "); if(!is_array($arr)) { $disorder = $minid; $evalue = $minid.'.001'; } else { $disorder = $minid; preg_match("#([0-9]{1,})\.([0-9]{1,})#", $arr['evalue'], $matchs); $addvalue = $matchs[2] + 1; $addvalue = sprintf("%03d", $addvalue); $evalue = $matchs[1].'.'.$addvalue; } $sql = "INSERT INTO `dede_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`) VALUES('$ename','$evalue','$egroup','$disorder','$issign'); "; // echo $sql;exit; $dsql->ExecuteNoneQuery($sql); } // echo $minid; WriteEnumsCache($egroup); ShowMsg("成功添加枚举分类！".$issign, $ENV_GOBACK_URL); exit(); } else { $minid = $topvalue; $maxid = $topvalue + 500; $enames = explode(',', $ename); foreach($enames as $ename) { $arr = $dsql->GetOne("Select * From `dede_sys_enum` where egroup='$egroup' And evalue>$minid And evalue<$maxid order by evalue desc "); if(!is_array($arr)) { $disorder = $evalue = $minid+1; } else { $disorder = $arr['disorder']+1; $evalue = (int)($arr['evalue']+1); } $dsql->ExecuteNoneQuery("Insert into `dede_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`) values('$ename','$evalue','$egroup','$disorder','$issign'); "); } WriteEnumsCache($egroup); ShowMsg("成功添加枚举分类！".$issign, $ENV_GOBACK_URL); exit(); } }  


二、找到：dede/templets/stepselect_main.htm文件将

if($topvalue % 500 != 0) $arr['issign'] = 2; 

替换为：

if($topvalue % 500 != 0) $arr['issign'] = 3;
if($topvalue % 500 == 0) $arr['issign'] = 2;

以上这样修改后1,2,3 联动能添加，再4级就不行了。应为这里的标记只判断到3，织梦也最多能添加3级联动。所以足够用了。
