名站网址导航为大驾家提供DedeCMS站点程序站点教程相关的知识，比如织梦程序安装教程,织梦程序系统故障等教程。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，以下相关具体操作方法解决此bug。
一、找到：dede/stepselect_main.php网站文件将以下替换源网站文件215行的对应相关具体代码如下
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("d", $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, $ENV_GOBACK_URL);
exit();
}
} |
二、找到：dede/templets/stepselect_main.htm网站文件将
if($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，织梦程序也最多能添加3级联动。所以足够用了。
