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
实现教程
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); } }

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'} <li> <a href="[field:arcurl/]"><img src="[field:litpic/]" width="50" height="50"></a> <p><a href="[field:arcurl/]">[field:title/]</a><span>时间:[field:pubdate function="MyDate('Y-m-d',@me)"/]</span></p> </li> {/dede:prenextdiy} 下一篇 {dede:prenextdiy get='next'} <li> <a href="[field:arcurl/]"><img src="[field:litpic/]" width="50" height="50"></a> <p><a href="[field:arcurl/]">[field:title/]</a><span>时间:[field:pubdate function="MyDate('Y-m-d',@me)"/]</span></p> </li> {/dede:prenextdiy}
