织梦5.7bug修复:后台联动不能添加二级栏目的解决

ゝ一世哀愁。 2021-09-25 18:06 117阅读 0赞

为客户安装的5.7新版后台，为了给客户添加一个产品的分类，我使用的分类信息，结果去添加联动属性的时候，发现只可以添加一级联动和三级联动。
    二级联动无法添加了。
    在自己的5.6的后台添加的时候，发现是可以的。估计又是5.7版本的bug了。
    
        于是分析了代码，和大家分享下解决的办法:
    
      
    
    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
            $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!", $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。
