dedecms 实现图集单击图片翻页的功能

1、为了实现这个功能，我们首先需要获得图片页面的当前页码和总页码 
编辑include/inc_archives_view.php文件 

（1）找到function ParseDMFields，修改为：

function ParseDMFields($pageNo,$ismake=1)  
{  
$this->NowPage = $pageNo;  
//获得当前页面编号  
$this->Fields['cpagenum'] = $this->NowPage;  
if($this->SplitPageField!="" &&  
isset($this->Fields[$this->SplitPageField]))  
{  
$this->Fields[$this->SplitPageField] = $this->SplitFields[$pageNo - 1];  
}  

注意增加了如下代码用来获得当前的页码:

$this->Fields['cpagenum'] = $this->NowPage;  

（2）找到function __construct构造函数，修改为：

$this->TotalPage = count($this->SplitFields);  
}  
//获得当前页面总数  
$this->Fields['totalpage'] = $this->TotalPage;  
$this->LoadTemplet();  
$this->ParseTempletsFirst();  
}  

$this->Fields['totalpage'] = $this->TotalPage;  

2、接下来在模板中用js实现分析静态页面和动态页面以及向下翻页  编辑article_image.htm或者你的图集最终显示的模板，增加如下js代码：

<script language="javascript">  
var npage = {dede:field/};  
var totalpage = {dede:field/};  
var filename="";  
var curl=location.href;  
 
function goNextPic(){  
str1 = /\.html/ig;  
str2 = /_/ig;  
r = curl.search(str1);  
r1 = curl.search(str2);  
if(r>0){  
if(npage==1) filename = curl.substr(0,r);  
else filename = curl.substr(0,r1);  
 
if(npage==totalpage){ location.href = filename+".html"; }  
else{  
location.href = filename+"_"+(npage+1)+".html";  
}  
}else{  
if(npage==totalpage){ location.href = "view.php?aid={dede:field/}"; }  
else{  
location.href = "view.php?aid={dede:field/}&pageno="+(npage+1);  
}  
}  
}  
</script>  

$revalue = "<center><a href='$src' target='_blank'><img src='$src' alt='$alt' $iw/></a><br/>$alt<br/></center>\r\n";  

$revalue = "<center><a href='javascript:goNextPic();'><img src='$src' alt='$alt' $iw/></a><br/>$alt<br/></center> ";
