dedecms5.7文章实现阅读全文功能二次开发
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 `#@__archives` SET ismake=1 WHERE .$this->ArcID."'");
在上一行添加以下代码:
- //阅读全文开始
- if($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');
- } //phpfensi.com
- }
- //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;
- }
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.
