织梦dedecms栏目添加自定义字段，增加栏目上传缩略图功能(2)
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 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 $myrow['typeimg']; else echo "images/pview.gif";?>" width="150" height="100" id="picview" name="picview"> </td> </tr> <!--增加栏目缩略图--> |
保存catalog_edit.htm。
至此已经修改完成!
栏目图片的添加或修改图片时在 (栏目管理>高级选项)里面就会自动出现栏目图片添加的选择，点击选择图片，弹出窗口内选择浏览上传就OK。
注意：前台栏目标签调用的时候，还需要改一个文件，才能实现栏目图片显示，否则只能通过sql语句才能显示图片。
第三步：缩略图调用
打开：include/taglib/channel.lib.php
找到
|
if($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); |
保存文件即可。
