织梦上一篇下一篇自由可控输出链接、标题、缩略图、时间方法

365ymw / 2020-03-20

在不影响织梦程序原来功能的基础下，织梦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')复

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
