dede栏目增加缩略图,dede增加栏目图片字段
用织梦dede做网站的时候,有时需要给栏目添加栏目的图片,即增加栏目的缩略图,下面给大家介绍一下如何添加栏目缩略图的方法,适用dede5.6 5.7.
新加字段 typeimg,后台执行SQL:
alter table `ant_arctype` add `typeimg` char(100) NOT NULL default '';
涉及到文件:
- dede/catalog_add.php
- dede/catalog_edit.php
- dede/templets/catalog_add.htm
- dede/templets/catalog_edit.htm
打开文件夹templets这个目录,在里面新建一个文件夹typeimg,用于独立存放栏目缩略图,打开dede/catalog_add.php.
查找$queryTemplate = "insert into `ant_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~',
打开dede/catalog_edit.php,查找:
$upquery = "Update `ant_arctype` set
在其下面新加一行:`typeimg`='$typeimg',
打开dede/templets/catalog_add.htm,查找:
- <tr>
- <td height="26">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="img/help.gif" alt="帮助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td>
- </tr>
在其下面增加以下内容:
- <tr>
- <td height="65">栏目图片:</td>
- <td>
- <input name="typeimg" type="text" style="width:250px" id="typeimg" class="alltxt" value="" />
- <input type="button" name="set9" value="浏览... "class="coolbg np" style="width:60px" onClick="SelectTemplets('form1.typeimg&activepath=%2Ftemplets%2Ftypeimg&img=yes');" />
- (栏目模板里用{dede:field.typeimg /}调用)
- </td>
- </tr>
打开dede/templets/catalog_edit.htm,查找:
- <tr>
- <td height="26">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="img/help.gif" alt="帮助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td>
- </tr>
在其下面新增以下内容:
- <tr>
- <td height="65">栏目图片:</td>
- <td>
- <input name="typeimg" type="text" style="width:250px" id="typeimg" class="alltxt" value="<?php echo $myrow['typeimg']?>" />
- <input type="button" name="set9" value="浏览... "class="coolbg np" style="width:60px" onClick="SelectImages('form1.typeimg&activepath=%2Ftemplets%2Ftypeimg&img=yes');" />
- (栏目模板里用{dede:field.typeimg /}调用)
- </td>
- </tr>
完成,添加或修改图片时在 栏目管理》高级选项.
如果想同时在文章内容页调用打开\include\arc.archives.class.php,查找:
if($this->ChannelUnit->ChannelInfos['issystem']!=-1)
将:
- $query = "Select arc.*,tp.reid,tp.typedir,ch.addtable
- from `ant_archives` arc
- left join ant_arctype tp on tp.id=arc.typeid
- left join ant_channeltype as ch on arc.channel = ch.id
- where arc.id='$aid' ";
- $this->Fields = $this->dsql->GetOne($query);
-
- $query = "Select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable
- from `ant_archives` arc
- left join ant_arctype tp on tp.id=arc.typeid
- left join ant_channeltype as ch on arc.channel = ch.id
- where arc.id='$aid' ";
- $this->Fields = $this->dsql->GetOne($query);
修改完毕后在后台添加栏目图片信息并保存的时候会出错,我检查了一下,发现是那行SQL命令有问题,dede的表中没有那个表,大家用的时候应修改那个表名.
