dede5.7 给栏目添加上缩略图

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` char(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:

<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>

　　列表命名规则：

<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 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

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

　　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 /]” />

　　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);

　　保存文件即可。
