DedeCms 欄目增加縮略圖功能的方法

時間:2020-12-15

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

  此升級修改方法,在V5.7,V5.7sp1 測試通過,其他版本未測試,原理基本相同,請大家自行測試是否可行。

  首先給 欄目表(`dede_arctype`)增加一個字段typeimg

alter table `dede_arctype` add `typeimg` varchar(200) NOT NULL default ;

 

  修改catalog_add.php文件

  打開dede/catalog_add.php

  查找$queryTemplate = “insert into `dede_arctype`

  將

(reid,topid,sortrank,typename,typedir,

 

  替換為:

(reid,topid,sortrank,typename,typedir,typeimg,

  將

(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,

  替換為:

(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,'~typeimg~’,

  查找$in_query = “INSERT INTO `dede_arctype`

  將

(reid,topid,sortrank,typename,typedir,

  替換為:

(reid,topid,sortrank,typename,typedir,typeimg,

  將

(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,

  替換為:

(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,'$typeimg’,

  保存catalog_add.php

  下面修改catalog_edit.php文件

  打開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

  開始修改欄目添加模板文件

  打開dede/templets/catalog_add.htm

  在最上面找到這個段

<title>欄目管理</title> <link href=”css/base.css” rel=”stylesheet” type=”text/css”>

 

  替換為:

<title>欄目管理</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>

 

  列表命名規則:

<tr> <td height="26" style="padding-left:10px;">列表命名規則:</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="幫助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td> </tr>

 

  在標簽下面增加一行:

<!--增加欄目縮略圖--> <tr> <td width="90" style="padding-left:10px;">欄目圖片:</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="本地上傳" 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="選擇圖片" 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'/>遠程<br />(欄目模板里用{dede:field.typeimg /}調用 </td> </tr> </table> </td> <td width="150" align="center"> <div id='divpicview' class='divpre'></div> </td> </tr> <!--增加欄目縮略圖-->

  保存catalog_add.htm

  開始修改欄目編輯模板文件

  打開dede/templets/catalog_edit.htm

  在最上面找到這個段

<title>欄目管理</title> <link href=”css/base.css” rel=”stylesheet” type=”text/css”>

 

  替換為:

<title>欄目管理</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;">列表命名規則:</td> <td> <input name="namerule2" type="text" id="namerule2" value="<?php echo $myrow['namerule2']?>" size="40" class="iptxt" /> <img src="images/help.gif" alt="幫助" width="16" height="16" border="0" style="cursor:pointer" onClick="ShowHide('helpvar3')"/></td> </tr>

 

  在其下面增加一行:

<!--增加欄目縮略圖--> <tr> <td width="90" height="81" style="padding-left:10px;">欄目圖片:</td></td> <td width="500"> <input name="typeimg" type="text" id="typeimg" style="width:300px" value="<?php echo $myrow['typeimg']?>"><input type="button" name="Submit" value="瀏覽..." style="width:70px" onClick="SelectImage('form1.typeimg','');"> <input type="button" name="Submit2" value="裁剪" style="margin-left:8px;" onClick="imageCut('typeimg');" class='np coolbg'/> <input type='checkbox' class='np' name='ddisremote' value='1'> 遠程<br />(欄目模板里用{dede:field.typeimg /}調用) </td> <td align="center"> <img src="<?php if($myrow['typeimg']!="") echo $myrow['typeimg']; else echo "images/pview.gif";?>" width="150" height="100" id="picview" name="picview"> </td> </tr> <!--增加欄目縮略圖-->

 

  保存catalog_edit.htm

  至此已經修改完成!

  欄目圖片的添加或修改圖片時在 (欄目管理>高級選項)里面就會自動出現欄目圖片添加的選擇,點擊選擇圖片,彈出窗口內選擇瀏覽上傳就OK

  注意:前臺欄目標簽調用的時候,還需要改一個文件,才能實現欄目圖片顯示,否則只能通過sql語句才能顯示圖片。

  打開: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"; }

 

  替換成下面的:

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"; }

 

  調用方法:

<img src=”[field:typeimg /]” />

 如果想同時在文章內容頁調用欄目圖片打開,修改\include\arc.archives.class.php

  查找

if($this->ChannelUnit->ChannelInfos['issystem']!=-1)

  將

$query = “Select arc.*,tp.reid,tp.typedir,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$aid’ “; $this->Fields = $this->dsql->GetOne($query);

  替換為: 

$query = “Select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$aid’ “; $this->Fields = $this->dsql->GetOne($query);

  保存文件即可。
