DEDECMS 为栏目增加栏目图片的办法-MAXWO.COM

MAXWO.COM这次教大家为实现每个栏目都有上传栏目缩略图的功能

修改方法如下：（本文中“dede_arctype”为DEDECMS默认数据库表，各位站长根据自己数据库表名修改）

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` char(100) 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

1、打开dede/catalog_add.php

查找

$queryTemplate = “INSERT INTO `#@__arctype`(reid,topid,sortrank,typename,typedir,

将

$queryTemplate = “INSERT INTO `#@__arctype`(reid,topid,sortrank,typename,typedir,

替换为

$queryTemplate = “INSERT INTO `#@__arctype`(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`(reid,topid,sortrank,typename,typedir,

替换为

$in_query = “INSERT INTO `#@__arctype`(reid,topid,sortrank,typename,typedir,typeimg,

保存dede/catalog_add.php

 

2、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

3.开始修改栏目添加模板文件

打开dede/templets/catalog_add.htm

将

<title>栏目管理</title>
<link href=”css/base.css” rel=”stylesheet” type=”text/css”>

替换成

<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>

在这里下面添加：

<!--增加栏目缩略图-->
<tr>
<td width="90" style="padding-left:10px;">栏目图片：</td>
<td width="560">
    <table width="100%" border="0" cellspacing="1" cellpadding="1">
    <tr>
      <td height="30">
      <input name="typeimg" type="text" id="typeimg" style="width:240px" />
      <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<br />(栏目模板里用{dede:field.typeimg /}调用
      </td>
    </tr>
  </table>
 </td>
<td width="150" align="center">
<div id='divpicview' class='divpre'></div>
</td>
</tr>
<!--增加栏目缩略图-->


保存catalog_add.htm


4.开始修改栏目编辑模板文件

打开dede/templets/catalog_edit.htm

 

查找

<title>栏目管理</title>
<link href=”css/base.css” rel=”stylesheet” type=”text/css”>

替换成

<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>

在这里下面增加

<!–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 $myrow[‘typeimg’]?>”><input type=”button” name=”Submit” value=”浏览…” style=”width:70px” onClick=”SelectImage(‘form1.typeimg’,”);”>
<input type=”button” name=”Submit2″ value=”裁剪” style=”margin-left:8px;” onClick=”imageCut(‘typeimg’);” class=’np coolbg’/>
<input type=’checkbox’ class=’np’ name=’ddisremote’ value=’1′>
远程<br />(栏目模板里用{dede:field.typeimg /}调用)
</td>
<td align=”center”>
<img src=”<?php if($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

 

大功告成！！！！

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

$query = “Select arc.*,tp.reid,tp.typedir,ch.addtable
from `#@__archives` arc
left join #@__arctype tp on tp.id=arc.typeid
left join #@__channeltype as ch on arc.channel = ch.id
where arc.id=’$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);

最后在需要调用的地方添加

{dede:field.typeimg /}

完美！！MAXWO.COM
