DEDECMS实现图集单击图片翻页的功能

  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();    }  

注意增加了如下代码用来获得总页码:

  $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>  

 在这个js脚本中，我们定义一个方法goNextPic用来切换到下一个图片。 

3、最后修改图片输出代码，完成goNextPic方法调用 

修改include/inc_channel_unit.php 
找到”//全部列出式或分页式图集”的部分。 
修改类似（仔细看代码，需要修改好几个地方）：

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

为：

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