此功能添加涉及到以下文件：
dede/catalog_add.php
dede/catalog_edit.php
dede/templets/catalog_add.htm
dede/templets/catalog_edit.htm
include/taglib/channel.lib.php
此升級修改方法，在V5.7，V5.7sp1 測試通過，其他版本未測試，原理基本相同，請大家自行測試是否可行。
首先給 欄目表(`dede_arctype`)增加一個字段typeimg
alter table `dede_arctype` add `typeimg` varchar(200) NOT NULL default ;修改catalog_add.php文件
打開dede/catalog_add.php
查找$queryTemplate = “insert into `dede_arctype`
將
(reid,topid,sortrank,typename,typedir,替換為：
(reid,topid,sortrank,typename,typedir,typeimg,將
(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,替換為：
(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,'~typeimg~’,查找$in_query = “INSERT INTO `dede_arctype`
將
(reid,topid,sortrank,typename,typedir,替換為：
(reid,topid,sortrank,typename,typedir,typeimg,將
(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,替換為：
(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,'$typeimg’,保存catalog_add.php
下面修改catalog_edit.php文件
打開dede/catalog_edit.php
查找$upquery = “Update `dede_arctype` set
在 typedir=’$typedir’, 其下面增加一行：
`typeimg`=’$typeimg’,保存catalog_edit.php
開始修改欄目添加模板文件
打開dede/templets/catalog_add.htm

開始修改欄目編輯模板文件

至此已經(jīng)修改完成!
欄目圖片的添加或修改圖片時在 (欄目管理>高級選項(xiàng))里面就會自動出現(xiàn)欄目圖片添加的選擇，點(diǎn)擊選擇圖片，彈出窗口內(nèi)選擇瀏覽上傳就OK
注意：前臺欄目標(biāo)簽調(diào)用的時候，還需要改一個文件，才能實(shí)現(xiàn)欄目圖片顯示，否則只能通過sql語句才能顯示圖片。
打開：include/taglib/channel.lib.php
找到
if($type=='top') { $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row"; } else if($type=="son") { //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid']; if($typeid==0) { return ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row"; } else if($type=="self") { if($reid==0) { return ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid='$reid' And ishidden<>1 order by sortrank asc limit 0,$row"; }替換成下面的：
if($type=='top') { $sql = "Select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row"; } else if($type=="son") { //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid']; if($typeid==0) { return ''; } $sql = "Select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row"; } else if($type=="self") { if($reid==0) { return ''; } $sql = "Select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid='$reid' And ishidden<>1 order by sortrank asc limit 0,$row"; }調(diào)用方法：
<img src=”[field:typeimg /]” />如果想同時在文章內(nèi)容頁調(diào)用欄目圖片打開，修改\include\arc.archives.class.php
查找
if($this->ChannelUnit->ChannelInfos['issystem']!=-1)將
$query = “Select arc.*,tp.reid,tp.typedir,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$aid’ “; $this->Fields = $this->dsql->GetOne($query);替換為：
$query = “Select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$aid’ “; $this->Fields = $this->dsql->GetOne($query);保存文件即可。
