在修改联动类别里面的信息类型的时候发现只能增加一级选择和三级选择，就是不能增加二级选择，怎么办呢？
首先咱们找到咱们的模板源码下面的 dede/stepselect_main.php 这个网站文件，
将这段相关具体代码如下
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 | 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.mzdh.net 织梦程序模板下载 $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("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！", $ENV_GOBACK_URL); exit(); } } |
替换为：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 | else if($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，在系统网站的后台更新系统系统缓存就可以了的。现在在网站的后台的联动类别管理里面就可以增加二级选择了。
