今天在做一个织梦DEDECMS装饰工程企业网站的时候,需要用到分类信息,模板是用的DEDECMS V5.7版本的,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3J选择,就是不能增加二级选择,怎么办呢?
去织梦官方找了下解决办法没得,看来只能自己研究了。
后来使用DEDECMSV5.6版本的进行测试,发现5.6的是可以使用的,那就可以找到解决的办法了。
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; // 3J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(\"%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。
