核心提示:DedeCms 栏目增加缩略图功能此功能添加涉及到以下文件:dede/catalog_add.phpdede/catalog_edit.phpdede/templets/catalog_add.h
<pre>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` varchar(200) NOT NULL default ;
修改catalog_add.php文件
 
打开dede/catalog_add.php
 
查找$queryTemplate = “insert into `#@__arctype`
 
 
(reid,topid,sortrank,typename,typedir,
替换为:
 
(reid,topid,sortrank,typename,typedir,typeimg,
 
(‘~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:
 
(reid,topid,sortrank,typename,typedir,typeimg,
 
(‘$reid’,'$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>

</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="https://www.hanlaba.com/skin/hanlaba/image/nopic.gif">
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)
 
$query = “Select arc.*,tp.reid,tp.typedir,ch.addtable
from `#@__archives` arc
left join #@__arctype tp on tp.id=arc.typeid
left join #@__channeltype as ch on arc.channel = ch.id
where arc.id=’$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);
收工。</pre>
