织梦DedeCMS上一篇下一篇自由可控输出链接、标题、缩略图、时间

在不影响程序原来功能的基础下，二次开发让上一篇下一篇标签自由可控地输出链接 | 标题 | 缩略图 | 时间，没有上一篇或者下一篇时不输出任何东西

打开 /include/arc.archives.class.php 找到 大概在 735 行左右的

else if($ctag->GetName()=='fieldlist')制

在它的上面加入

else if($ctag->GetName()=='prenextdiy'){$innertext = trim($ctag->GetInnerText());if($innertext){$get = $ctag->GetAtt('get');$diys['diy'] = $this->GetPreNext('diy');$revalue = '';$dtp2 = new DedeTagParse();$dtp2->SetNameSpace('field','[',']');$dtp2->LoadSource($innertext);foreach($diys as $row){foreach($dtp2->CTags as $tid=>$ctag2){if(isset($row[$get][$ctag2->GetName()])){$dtp2->Assign($tid,$row[$get][$ctag2->GetName()]);}}$revalue .= $dtp2->GetResult();}if($row[$get]['id']) $this->dtp->Assign($i,$revalue);}}

如图

继续找到，大概在852行左右的

$this->PreNext['pre'] = "上一篇：{$preRow['title']} ";

在它的上面加入

$preRow['litpic'] = (empty($preRow['litpic'])) ? $GLOBALS['cfg_cmspath'].'/images/defaultpic.jpg' : $preRow['litpic'];$this->PreNext['diy']['pre']['id'] = $preRow['id'];$this->PreNext['diy']['pre']['arcurl'] = https://www.liuzhongwei.com/a/dedejq/$mlink;$this->PreNext['diy']['pre']['title'] = $preRow['title'];$this->PreNext['diy']['pre']['litpic'] = $preRow['litpic'];$this->PreNext['diy']['pre']['pubdate'] = $preRow['senddate'];

如图

继续找到，大概在875行左右的

$this->PreNext['next'] = "下一篇：{$nextRow['title']} ";

在它的上面加入

$nextRow['litpic'] = (empty($nextRow['litpic'])) ? $GLOBALS['cfg_cmspath'].'/images/defaultpic.jpg' : $nextRow['litpic'];$this->PreNext['diy']['next']['id'] = $nextRow['id'];$this->PreNext['diy']['next']['arcurl'] = https://www.liuzhongwei.com/a/dedejq/$mlink;$this->PreNext['diy']['next']['title'] = $nextRow['title'];$this->PreNext['diy']['next']['litpic'] = $nextRow['litpic'];$this->PreNext['diy']['next']['pubdate'] = $nextRow['senddate'];

如图

if($gtype=='pre')

在它的上面加入

if($gtype=='diy'){return $this->PreNext['diy'];}

内容页模板里上一篇下一篇调用标签写法

上一篇{dede:prenextdiy get='pre'}
[field:title/]时间:[field:pubdate function="MyDate('Y-m-d',@me)"/]
{/dede:prenextdiy}下一篇{dede:prenextdiy get='next'}
[field:title/]时间:[field:pubdate function="MyDate('Y-m-d',@me)"/]
{/dede:prenextdiy} 

注意：标签是自定义的dede:prenextdiy
