dedecms5.7文章二次开发实现阅读全文功能的方法
本文实例讲述了dedecms5.7文章二次开发实现阅读全文功能的方法。分享给大家供大家参考。具体分析如下:
阅读全文功能其实在很多的流行站点都有的,比如网易,新浪等,随着文章内容的增加,当一个页面有多个分页的时候,就会显示出这个“在本页阅读全文”的链接,点击这个链接之后出现的,将是这篇文章以没有分页出现的型式,那么在dedecms5.7如何在文章内容页添加阅读全文功能呢?
这个阅读全文有什么用呢?说白了,也就是提高用户体验,下面让我们看看,怎么简单现实这个功能.
修改文件:include/arc.archives.class.php
注意:做任何修改前都要备份好原文件.
第一步:打开include/arc.archives.class.php
文件查找://issystem==-1
往下 大概 145行 找到:
$this->Fields['userip'] = $this->addTableRow['userip'];
在下面一行添加:
$this->Fields['body2'] = $this->addTableRow['body'];
第二步查找:
$this->dsql->ExecuteNoneQuery("Update `dede_archives` SET ismake=1 WHERE id='".$this->ArcID."'");
在上一行添加以下代码:
//阅读全文开始
if($this->TotalPage > 1) {
//用正则匹配把分页符去掉
$this->Fields['body2'] = preg_replace('/# p#副标题# e#/U', '',$this->Fields['body2']);
$this->SplitFields = explode("#p2222#",$this->Fields['body2']);
$this->Fields['tmptitle'] = (emptyempty($this->Fields['tmptitle']) ? $this->Fields['title'] : $this->Fields['tmptitle']);
$this->Fields['title'] = $this->Fields['tmptitle'];
$this->TotalPage = count($this->SplitFields);
$this->Fields['totalpage'] = $this->TotalPage;
$TRUEfilenameall = $this->GetTruePath().$fileFirst."_all.".$this->ShortName;
$this->ParseDMFields(1,0);
$this->dtp->SaveTo($TRUEfilenameall);
if($cfg_remote_site=='Y' && $isremote == 1)
{
//分析远程文件路径
$remotefile = str_replace(DEDEROOT, '', $TRUEfilename);
$localfile = '..'.$remotefile;
//创建远程文件夹
$remotedir = preg_replace("#[^\/]*\.html#", '', $remotefile);
$this->ftp->rmkdir($remotedir);
$this->ftp->upload($localfile, $remotefile, 'ascii');
}
}
//阅读全文结束
if($this->TotalPage > 1) {
//用正则匹配把分页符去掉
$this->Fields['body2'] = preg_replace('/# p#副标题# e#/U', '',$this->Fields['body2']);
$this->SplitFields = explode("#p2222#",$this->Fields['body2']);
$this->Fields['tmptitle'] = (emptyempty($this->Fields['tmptitle']) ? $this->Fields['title'] : $this->Fields['tmptitle']);
$this->Fields['title'] = $this->Fields['tmptitle'];
$this->TotalPage = count($this->SplitFields);
$this->Fields['totalpage'] = $this->TotalPage;
$TRUEfilenameall = $this->GetTruePath().$fileFirst."_all.".$this->ShortName;
$this->ParseDMFields(1,0);
$this->dtp->SaveTo($TRUEfilenameall);
if($cfg_remote_site=='Y' && $isremote == 1)
{
//分析远程文件路径
$remotefile = str_replace(DEDEROOT, '', $TRUEfilename);
$localfile = '..'.$remotefile;
//创建远程文件夹
$remotedir = preg_replace("#[^\/]*\.html#", '', $remotefile);
$this->ftp->rmkdir($remotedir);
$this->ftp->upload($localfile, $remotefile, 'ascii');
}
}
//阅读全文结束
第三步:查找 获得静态页面分页列表,代码如下:
/**
* 获得静态页面分页列表
*
* @access public
* @param int $totalPage 总页数
* @param int $nowPage 当前页数
* @param int $aid 文档id
* @return string
*/
function GetPagebreak($totalPage, $nowPage, $aid)
{
if($totalPage==1)
{
return "";
}
//$PageList = "<li><a>共".$totalPage."页: </a></li>";
$PageList = "";
$nPage = $nowPage-1;
$lPage = $nowPage+1;
if($nowPage==1)
{
$PageList.="<a href='javascript:void(0);'><</a>";
}
else
{
if($nPage==1)
{
$PageList.="<a href='".$this->NameFirst.".".$this->ShortName."' target='_self'><</a>";
}
else
{
$PageList.="<a href='".$this->NameFirst."_".$nPage.".".$this->ShortName."' target='_self'><</a>";
}
}
for($i=1;$i<=$totalPage;$i++)
{
if($i==1)
{
if($nowPage!=1)
{
$PageList.="<a href='".$this->NameFirst.".".$this->ShortName."' target='_self'>1</a>";
}
else
{
$PageList.="<a class=\"here\" href='javascript:void(0);' target='_self'>1</a>";
}
}
else
{
$n = $i;
if($nowPage!=$i)
{
$PageList.="<a href='".$this->NameFirst."_".$i.".".$this->ShortName."' target='_self'>".$n."</a>";
}
else
{
$PageList.="<a class=\"here\" href='javascript:void(0);' target='_self'>{$n}</a>";
}
}
}
if($lPage <= $totalPage)
{
$PageList.="<a href='".$this->NameFirst."_".$lPage.".".$this->ShortName."' target='_self'>></a>";
}
else
{
$PageList.= "<a href='javascript:void(0);'>></a>";
}
$PageList.= "<a href='".$this->NameFirst."_all.".$this->ShortName."'>阅读全文</a>";
return $PageList;
}
* 获得静态页面分页列表
*
* @access public
* @param int $totalPage 总页数
* @param int $nowPage 当前页数
* @param int $aid 文档id
* @return string
*/
function GetPagebreak($totalPage, $nowPage, $aid)
{
if($totalPage==1)
{
return "";
}
//$PageList = "<li><a>共".$totalPage."页: </a></li>";
$PageList = "";
$nPage = $nowPage-1;
$lPage = $nowPage+1;
if($nowPage==1)
{
$PageList.="<a href='javascript:void(0);'><</a>";
}
else
{
if($nPage==1)
{
$PageList.="<a href='".$this->NameFirst.".".$this->ShortName."' target='_self'><</a>";
}
else
{
$PageList.="<a href='".$this->NameFirst."_".$nPage.".".$this->ShortName."' target='_self'><</a>";
}
}
for($i=1;$i<=$totalPage;$i++)
{
if($i==1)
{
if($nowPage!=1)
{
$PageList.="<a href='".$this->NameFirst.".".$this->ShortName."' target='_self'>1</a>";
}
else
{
$PageList.="<a class=\"here\" href='javascript:void(0);' target='_self'>1</a>";
}
}
else
{
$n = $i;
if($nowPage!=$i)
{
$PageList.="<a href='".$this->NameFirst."_".$i.".".$this->ShortName."' target='_self'>".$n."</a>";
}
else
{
$PageList.="<a class=\"here\" href='javascript:void(0);' target='_self'>{$n}</a>";
}
}
}
if($lPage <= $totalPage)
{
$PageList.="<a href='".$this->NameFirst."_".$lPage.".".$this->ShortName."' target='_self'>></a>";
}
else
{
$PageList.= "<a href='javascript:void(0);'>></a>";
}
$PageList.= "<a href='".$this->NameFirst."_all.".$this->ShortName."'>阅读全文</a>";
return $PageList;
}
也就是在return $PageList 上一行添加了一行代码:
$PageList.= "<a href='".$this->NameFirst."_all.".$this->ShortName."'>阅读全文</a>";
修改完成后,保存文件,更新一下页面就可以看到效果了.
