织梦dedecms联动信息不能调用二级选项的解决办法

本文介绍了织梦dedecms联动信息不能调用二级选项的解决办法，解决思路：打开这个文件stepselect_main.php，根据教程的提示，找到旧代码改为新的就可以了。具体看教程说明吧。

织梦dedecms联动信息不能调用二级选项的解决办法？修改联动类别中的信息类型时，发现只能增加一级选择和三级选择，也就是说不能增加二级选择。我该怎么办？下面就来说说织梦调用二级选项办法。

处理办法：

首先我们找到我们的模板源码下面的 dede/stepselect_main.php 这个文件，

将这段代码

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 == 2 && $topvalue != 0)

{

$minid = $topvalue;

$maxnum = 500; // 三级子类最多500个www.dede58.com织梦模板下载

$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！", $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 = $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！", $ENV_GOBACK_URL);

exit();

}

}

替换为：

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 evalue 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

{

$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 = $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！", $ENV_GOBACK_URL);

exit();

}

}

然后保存，在系统后台更新系统缓存就可以了的。现在在后台的联动类别管理里面就可以增加二级选择了。
