织梦dedecms栏目添加自定义字段，增加栏目上传缩略图功

请提交问题反馈我们用织梦制作企业网站时，点击进入每个栏目时，都会有“关于我们”，“新闻中心”，“产品展示”等提示性的图片，单独调用这些图片比较麻烦，我们可以修改程序，实现每个栏目都有上传栏目缩略图的功能，就方便多了。(如本站异常，请点击查看这里)

第一步：执行SQL命令为数据库的栏目表结构添加一个字段

alter table `dede_arctype` add `typeimg` varchar(200) NOT NULL default ;

第二步：修改涉及到文件：
dede/catalog_add.php
dede/catalog_edit.php
dede/templets/catalog_add.htm
dede/templets/catalog_edit.htm
include/taglib/channel.lib.php

1、修改dede/catalog_add.php文件
打开查找

$queryTemplate = "INSERT INTO

查找到以上内容后，再将后面增加一个字段typeimg

$queryTemplate = "INSERT INTO `dede_arctype`(reid,topid,sortrank,typename,tuiguang,guanwang,typedir,

增加后：

$queryTemplate = "INSERT INTO `dede_arctype`(reid,topid,sortrank,typename,tuiguang,guanwang,typedir,typeimg,

查找以下内容，添加字段typeimg

VALUES('~reid~','~topid~','~rank~','~typename~','~typedir~',

增加字段后：

VALUES('~reid~','~topid~','~rank~','~typename~','$typeimg','~typedir~',

查找

$in_query = "INSERT INTO

查找以下内容，添加字段typeimg

$in_query = "INSERT INTO `dede_arctype`(reid,topid,sortrank,typename,typedir,

替换为：

$in_query = "INSERT INTO `dede_arctype`(reid,topid,sortrank,typename,typeimg,typedir,

查找以下内容，添加字段typeimg

VALUES('$reid','$topid','$sortrank','$typename','$typedir',

替换为：

VALUES('$reid','$topid','$sortrank','$typename','$typeimg','$typedir',

保存catalog_add.php。
2、修改dede/catalog_edit.php文件 查找

$upquery = "UPDATE `dede_arctype` SET

在 typedir=’$typedir’, 其下面增加一行：

`typeimg`=’$typeimg’,

保存catalog_edit.php。
2、修改dede/templets/catalog_add.htm文件 在最上面找到这段代码

<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="{typedir}/list_{tid}_{page}.html"  class="pubinputs"  style="width:250px" />
    <img src="images/help.gif" alt="帮助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td>
</tr>

在标签下面增加一行：

<!--增加栏目缩略图-->
<tr>
  <td height="165" style="padding-left:10px;">栏目图片：</td>
  <td>
        <input name="typeimg" type="text" id="typeimg" style="width:320px" />
        <input type="button"  value="本地上传" style="width:70px;cursor:pointer;display:none" />
        <iframe name='uplitpicfra' id='uplitpicfra' src='' style='display:none'></iframe>
        <span class="litpic_span"><input name="litpic" type="file" id="litpic"  onChange="SeePicNew(this, 'divpicview', 'uplitpicfra', 165, 'archives_add.php');" size="1" class='np coolbg'/></span>
        <input type="button" name="Submit2" value="选择图片" style="margin-left:8px;" onClick="SelectImage('form1.typeimg','small');" class='np coolbg'/>
        <input type="button" name="Submit2" value="裁剪" style="margin-left:8px;" onClick="imageCut('typeimg');" class='np coolbg'/>
        <input type='checkbox' class='np' name='ddisremote' value='1' id='ddisremote'/>远程({dede:field.typeimg /}调用
  <div id='divpicview' class='divpre'></div>
  </td>
</tr>
<!--增加栏目缩略图-->

保存catalog_add.htm。
3、修改dede/templets/catalog_edit.htm文件 在最上面找到这段代码

<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 height="165" style="padding-left:10px;">栏目图片：</td></td>
            <td>
             <input name="typeimg" type="text" id="typeimg" style="width:320px"  value="<?php echo $myrow['typeimg']?>"> <input type="button" name="Submit" value="浏览..." style="width:70px" onClick="SelectImage('form1.typeimg','');">
             <input type="button" name="Submit2" value="裁剪" style="margin-left:8px;" onClick="imageCut('typeimg');" class='np coolbg'/>
             <input type='checkbox' class='np' name='ddisremote' value='1'>
             远程({dede:field.typeimg /}调用)
            <img src="<?php if($myrow['typeimg']!="") echo $myrow['typeimg']; else echo "images/pview.gif";?>" width="150" height="100" id="picview" name="picview">
            </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。

第三步：缩略图调用打开：include/taglib/channel.lib.php找到

if($type=='top')
{
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
From `dede_arctype` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$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";
}

替换成下面的：

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";
}

调用方法：<img src=”[field:typeimg /]” />

第四步：文章内容页调用

如果想同时在文章内容页调用栏目图片打开，修改\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);
