dedecms联动问题

首先在空间里找到dede/stepselect_main.php 这个文件，然后找到其中的这段代码：
1else if($action=='addenum_save')
2{
3if(emptyempty($ename) || emptyempty($egroup))
4{
5Showmsg("类别名称或组名称不能为空！","-1");
6exit();
7}
8if($issign == 1 || $topvalue == 0)
9{
10$enames = explode(',', $ename);
11foreach($enames as $ename)
12{
13$arr = $dsql->GetOne("SELECT * FROM `#@__sys_enum`
WHERE egroup='$egroup' AND (evalue MOD 500)=0 ORDER BY disorder DESC ");
14if(!is_array($arr)) $disorder = $evalue = ($issign==1 ? 1 : 500);
15else $disorder = $evalue = $arr['disorder'] + ($issign==1 ? 1 : 500);
16
17$dsql->ExecuteNoneQuery("INSERT INTO
`#@__sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`)
18
VALUES('$ename','$evalue','$egroup','$disorder','$issign'); ");
19}
20WriteEnumsCache($egroup);
21ShowMsg("成功添加枚举分类！".$dsql->GetError(),
$ENV_GOBACK_URL);
22exit();
23} else if ($issign == 3 && $topvalue != 0)
24{
25$minid = $topvalue;
26$maxnum = 500; // 三级子类最多500个
27$enames = explode(',', $ename);
28foreach ($enames as $ename)
29{
30$arr = $dsql->GetOne("SELECT * FROM `#@__sys_enum`
WHERE egroup='$egroup' AND evalue LIKE '$topvalue.%%%' ORDER BY evalue DESC ");
31if(!is_array($arr))
32{
33$disorder = $minid;
34$evalue = $minid.'.001';
35}
36else
37{
38$disorder = $minid;
39preg_match("#([0-9]{1,})\.([0-9]{1,})#", $arr['evalue'], $matchs); 40$addvalue = $matchs[2] + 1;
41$addvalue = sprintf("%03d", $addvalue);
42$evalue = $matchs[1].'.'.$addvalue;
43}
44$sql = "INSERT INTO
`#@__sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`)
45
VALUES('$ename','$evalue','$egroup','$disorder','$issign'); ";
46// echo $sql;exit;
47$dsql->ExecuteNoneQuery($sql);
48}
49// echo $minid;
50WriteEnumsCache($egroup);
51ShowMsg("成功添加枚举分类！".$issign, $ENV_GOBACK_URL);
52exit();
53} else {
54$minid = $topvalue;
55$maxid = $topvalue + 500;
56$enames = explode(',', $ename);
57foreach($enames as $ename)
58{
59$arr = $dsql->GetOne("Select * From `dede_sys_enum` where
egroup='$egroup' And evalue>$minid And evalue<$maxid order by evalue desc "); 60if(!is_array($arr))
61{
62$disorder = $evalue = $minid+1;
63}
64else
65{
66$disorder = $arr['disorder']+1;
67$evalue = (int)($arr['evalue']+1);
68}
69$dsql->ExecuteNoneQuery("Insert into
`dede_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`)
70
values('$ename','$evalue','$egroup','$disorder','$issign'); ");
71}
72WriteEnumsCache($egroup);
73ShowMsg("成功添加枚举分类！".$issign, $ENV_GOBACK_URL);
74exit();
75}
76}
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。

2.dede/templets/stepselect_main.htm找到
if($topvalue % 500 != 0) $arr['issign'] = 2;
修改为
if($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。
