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

此升级修改方法，在V5.7，V5.7sp1 测试通过，其他版本未测试，原理基本相同，请大家自行测试是否可行。

首先给 栏目表(`#@__arctype`)增加一个字段typeimg

alter table `#@__arctype` add `typeimg` varchar(200) NOT NULL default ;

修改catalog_add.php文件

打开dede/catalog_add.php

查找$queryTemplate = “insert into `#@__arctype`

将

(reid,topid,sortrank,typename,typedir,

替换为：

(reid,topid,sortrank,typename,typedir,typeimg,

将

(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,

替换为：

(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,'~typeimg~’,

查找$in_query = “INSERT INTO `#@__arctype`

将

(reid,topid,sortrank,typename,typedir,

替换为：

(reid,topid,sortrank,typename,typedir,typeimg,

将

(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,

替换为：

(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,'$typeimg’,

保存catalog_add.php

下面修改catalog_edit.php文件

打开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

开始修改栏目添加模板文件

打开dede/templets/catalog_add.htm

在最上面找到这个段

<title>栏目管理</title>

<link href=”css/base.css” rel=”stylesheet” type=”text/css”>

替换为:

在标签下面增加一行：

<td width="150" align="center">

<!--增加栏目缩略图-->

保存catalog_add.htm

开始修改栏目编辑模板文件

打开dede/templets/catalog_edit.htm

在最上面找到这个段

<title>栏目管理</title>

<link href=”css/base.css” rel=”stylesheet” type=”text/css”>

替换为:

<title>栏目管理</title>

<link href=”css/base.css” rel=”stylesheet” type=”text/css”>

<script language=”javascript” src=”../include/js/dedeajax2.js”></script>

<script language=”javascript” src=”js/main.js”></script>

<script type=”text/javascript” src=”js/calendar/calendar.js”></script>

查找

<tr>

<td height="26" style="padding-left:10px;">列表命名规则：</td>

<td> <input name="namerule2" type="text" id="namerule2" value="<?php echo $myrow['namerule2']?>" size="40" class="iptxt" />

<img src="images/help.gif" alt="帮助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td>

</tr>

在其下面增加一行：

<!--增加栏目缩略图-->

<tr>

<td width="90" height="81" style="padding-left:10px;">栏目图片：</td></td>

<td width="500">

<input name="typeimg" type="text" id="typeimg" style="width:300px" value="<?php echo $myrow['typeimg']?>"><input type="button" name="Submit" value="浏览..." style="width:70px" onClick="SelectImage('form1.typeimg','');">

</td>

</tr>

<!--增加栏目缩略图-->

保存catalog_edit.htm

至此已经修改完成!

栏目图片的添加或修改图片时在 (栏目管理>高级选项)里面就会自动出现栏目图片添加的选择，点击选择图片，弹出窗口内选择浏览上传就OK

注意：前台栏目标签调用的时候，还需要改一个文件，才能实现栏目图片显示，否则只能通过sql语句才能显示图片。

打开：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";

}

替换成下面的：

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";

}

调用方法：

<img src=”[field:typeimg /]” />

最近有很多网友问到修改的方法，现在我把已经修改好的后台文件分享出来，下载下来直接覆盖到后台就可以了。http://115.com/file/anqwqyi0

如果想同时在文章内容页调用栏目图片打开，修改includearc.archives.class.php

查找

if($this->ChannelUnit->ChannelInfos['issystem']!=-1)

将

$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);

替换为：　

$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);
