advancedsearch.php织梦dedecms 高级自定义模型字段无法调用解决方案 ，具体步骤如下：
1 打开修改puls/advancedsearch.php文件，找到复制代码（不同版本可能有所差别）。
$query = "SELECT addon.*, arctype.* FROM $addontable addon
LEFT JOIN arctype ON arctype.id = addon.typeid
$where $orderby";
} else {
$query = "SELECT main.id AS aid,main.*,main.description AS description1, type.*
FROM $maintable main
LEFT JOIN type ON type.id = main.typeid
LEFT JOIN $addontable addon ON addon.aid = main.id
$where $orderby";
如果是5.7以前的版本
$query = "SELECT addon.*, arctype.* FROM $addontable addon
这一段是没有 addon 的！
复制这段加上即可！
2 然后 再改这段
else {
$query = "SELECT main.id AS aid,main.*,main.description AS description1, type.*
FROM $maintable main
LEFT JOIN type ON type.id = main.typeid
LEFT JOIN $addontable addon ON addon.aid = main.id
$where $orderby";
5.7所有的版本 都要改这段 改成：
else {
$query = "select addon.*,main.id as aid,main.*,main.description as description1, type.*
from $maintable main
left join dede_arctype type on type.id=main.typeid
left join $addontable addon on addon.aid=main.id
$where $orderby";
就是
$query = "SELECT main.id AS aid,main.*,main.description AS description1, type.*
这段改成
$query = "select addon.*,main.id as aid,main.*,main.description as description1, type.*
这样即可！
所以所有版本改后的代码为：
$query = "select addon.*, arctype.* from $addontable addon
left join dede_arctype arctype on arctype.id=addon.typeid
$where $orderby";
} else {
$query = "select addon.*,main.id as aid,main.*,main.description as description1, type.*
from $maintable main
left join dede_arctype type on type.id=main.typeid
left join $addontable addon on addon.aid=main.id
$where $orderby";
