织梦dedecms栏目添加自定义字段,增加栏目上传缩

我们用织梦制作企业网站时,点击进入每个栏目时,都会有“关于我们”,“新闻中心”,“产品展示”等提示性的图片,单独调用这些图片比较麻烦,我们可以修改程序,实现每个栏目都有上传栏目缩略图的功能,就方便多了。

织梦dedecms栏目添加自定义字段,增加栏目上传缩略图功能

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` varchar(200) 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

include/taglib/channel.lib.php

1、修改dede/catalog_add.php文件

打开查找

$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。

2、修改dede/catalog_edit.php文件

查找

$upquery = “Update `dede_arctype` set

在 typedir=’$typedir’, 其下面增加一行:

`typeimg`=’$typeimg’,

保存catalog_edit.php。

2、修改dede/templets/catalog_add.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="{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。

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)

$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。
