DEDECMS织梦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

实现教程

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

代码语言：javascript复制

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

在它的 上面 加入

代码语言：javascript复制

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);
	}
}复制

如图

内容页模板里上一篇下一篇调用标签写法

代码语言：javascript复制

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} 

注意：标签是自定义的 dede:prenextdiy
