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(`#@__arctype`)增加一個字段typeimg

alter table `#@__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 `#@__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 `#@__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 `#@__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

在最上面找到這個段

打開dede/templets/catalog_edit.htm

在最上面找到這個段

保存catalog_edit.htm

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)里面就會自動出現(xiàn)欄目圖片添加的選擇，點擊選擇圖片，彈出窗口內(nèi)選擇瀏覽上傳就ok

注意：前臺欄目標簽調(diào)用的時候，還需要改一個文件，才能實現(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 `#@__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 `#@__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 `#@__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 `#@__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 `#@__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 `#@__arctype` where reid='$reid' and ishidden<>1 order by sortrank asc limit 0,$row;

}

調(diào)用方法：

<img src=”[field:typeimg /]” />

最近有很多網(wǎng)友問到修改的方法，現(xiàn)在我把已經(jīng)修改好的后臺文件分享出來，下載下來直接覆蓋到后臺就可以了。http://115.com/file/anqwqyi0

如果想同時在文章內(nèi)容頁調(diào)用欄目圖片打開，修改includearc.archives.class.php

查找

if($this->channelunit->channelinfos['issystem']!=-1)

將

$query = “select arc.*,tp.reid,tp.typedir,ch.addtable

from `#@__archives` arc

left join #@__arctype tp on tp.id=arc.typeid

left join #@__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 `#@__archives` arc

left join #@__arctype tp on tp.id=arc.typeid

left join #@__channeltype as ch on arc.channel = ch.id

where arc.id=’$aid’ “;

$this->fields = $this->dsql->getone($query);
