新加字段 typeimg
后台执行SQL:

alter table `dede_arctype` add `typeimg` char(100) NOT NULL default '';

涉 及到文件：
        dede/catalog_add.php
               dede/catalog_edit.php
               dede/templets/catalog_add.htm
               dede/templets/catalog_edit.htm

打开文件夹templets这个目录，在里面新建一个文件夹 typeimg，用于独立存放栏目缩略图


打开dede/catalog_add.php
查 找$queryTemplate = "insert into `dede_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~',

打 开dede/catalog_edit.php
查找

$upquery = "Update `dede_arctype` set

在 其下面新加一行

`typeimg`='$typeimg',

打 开dede/templets/catalog_add.htm
查找

<tr>             <td height="26">列表命名规则：</td>             <td>               <input name="namerule2" type="text" id="namerule2" value="{typedir}/list_{tid}_{page}.html"  class="pubinputs"  style="width:250px" />               <img src="img/help.gif" alt="帮助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td>           </tr>

在 其下面增加以下内容

<tr>             <td height="65">栏目图片：</td>             <td>                 <input name="typeimg" type="text" style="width:250px" id="typeimg" class="alltxt" value="" /> <input type="button" name="set9" value="浏览... "class="coolbg np" style="width:60px" onClick="SelectTemplets('form1.typeimg&activepath=%2Ftemplets%2Ftypeimg&img=yes');" />                 (栏目模板里用{dede:field.typeimg /}调用)             </td>           </tr>

打 开dede/templets/catalog_edit.htm
查找

<tr>             <td height="26">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="img/help.gif" alt="帮助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td>           </tr>

在 其下面新增以下内容

<tr>             <td height="65">栏目图片：</td>             <td>                 <input name="typeimg" type="text" style="width:250px" id="typeimg" class="alltxt" value="<?php echo $myrow['typeimg']?>" />                 <input type="button" name="set9" value="浏览... "class="coolbg np" style="width:60px" onClick="SelectImages('form1.typeimg&activepath=%2Ftemplets%2Ftypeimg&img=yes');" />                 (栏目模板里用{dede:field.typeimg /}调用)             </td>           </tr>

完 成！

添加或修改图片时在 栏目管理》高级选项


如果想同时在文章内容页调用打开\include \arc.archives.class.php
查找

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

将

$query = "Select arc.*,tp.reid,tp.typedir,ch.addtable                 from `dede_archives` arc                          left join dede_arctype tp on tp.id=arc.typeid                           left join dede_channeltype as ch on arc.channel = ch.id                           where arc.id='$aid' ";                 $this->Fields = $this->dsql->GetOne($query);

替 换为

$query = "Select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable                 from `dede_archives` arc                          left join dede_arctype tp on tp.id=arc.typeid                           left join dede_channeltype as ch on arc.channel = ch.id                           where arc.id='$aid' ";                 $this->Fields = $this->dsql->GetOne($query);
