DedeCms 栏目增加缩略图功能的方法

  • A+
所属分类:建站相关

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(`dede_arctype`)增加一个字段typeimg

alter table `dede_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 `dede_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 `dede_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 `dede_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="DedeCms 栏目增加缩略图功能的方法" 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="DedeCms 栏目增加缩略图功能的方法" 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 $myrow['typeimg']?>"><input type="button" name="Submit" value="浏览..." style="width:70px" onClick="SelectImage('form1.typeimg','');"> <input type="button" name="Submit2" value="裁剪" style="margin-left:8px;" onClick="imageCut('typeimg');" class='np coolbg'/> <input type='checkbox' class='np' name='ddisremote' value='1'> 远程<br />(栏目模板里用{dede:field.typeimg /}调用) </td> <td align="center"> <img src="<?php%20if($myrow['typeimg']!="") echo $myrow['typeimg']; else echo "images/pview.gif" alt="DedeCms 栏目增加缩略图功能的方法";?>" 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') { $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$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 /]” />

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)

$query = “Select arc.*,tp.reid,tp.typedir,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$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。
