How to call random articles on dedecms homepage

dedecms首页怎么调用随机文章?

本文实例讲述了dedecms首页调用随机文章及自动更新功能的实现方法。分享给大家供大家参考。具体实现方法如下:

推荐学习:织梦cms

我们知道织梦多数情况下是生成静态的html文件的,这样一方面可以减少服务器的负荷,另一方面也是为了优化,但是织梦本身静态要手动更新生成,不是自动的,今天我们就来说一下怎样实现自动更新.

(1)调用随机文章:

织梦给出了随机文章调用的参数如下:

代码如下:

{dede:arclist sort='rand' titlelen=48 row=16} 
<li><a href="[field:arcurl/]" title="[field:title/]" target="_blank">[field:title/]</a></li> 
{/dede:arclist}

(2)置定时自动更新文件:

复制下面代码,粘贴到一个新文件中,命名为:autoindex.php,上传到ftp的plus文件夹中,看清楚一点是plus文件夹中,错了位置不会生效.

代码如下:

<?php 
function sp_input( $text ) 
{ 
$text = trim( $text ); 
$text = htmlspecialchars( $text ); 
if (!get_magic_quotes_gpc()) 
return addslashes( $text ); 
else 
return $text; 
} 
$autotime = 3600;//自动更新时间,单位为秒,这里我设为一小时,大家可以自行更改。 
$fpath = "../data/last_time.inc";//记录更新时间文件,如果不能达到目的,请检查是否有读取权限。 
include( $fpath ); 
if( emptyempty($last_time)) 
$last_time = 0; 
if( sp_input($_GET[&#39;renew&#39;])=="now") 
$last_time = 0; 
if((time()-$last_time)>=$autotime ) 
{ 
define(&#39;DEDEADMIN&#39;, ereg_replace("[/\\]{1,}",&#39;/&#39;,dirname(__FILE__) ) ); 
require_once(DEDEADMIN."/../include/common.inc.php"); 
require_once(DEDEINC."/arc.partview.class.php"); 
$templet = "tnbjh/index.htm";//这里是首页模板位置,当前是dede默认首面位置。 
$position = "../index.html"; 
$homeFile = dirname(__FILE__)."/".$position; 
$homeFile = str_replace("\\", "/", $homeFile ); 
$homeFile = str_replace( "//", "/", $homeFile ); 
$pv = new PartView(); 
$pv ->SetTemplet( $cfg_basedir.$cfg_templets_dir."/".$templet ); 
$pv -> SaveToHtml( $homeFile ); 
$pv -> Close();
$file = fopen( $fpath, "w"); 
fwrite( $file, "<?php\n"); 
fwrite( $file,"\$last_time=".time().";\n"); 
fwrite( $file, &#39;?>&#39; ); 
fclose( $file ); 
} 
?>

然后我们需要在首页的模版代码head标签中加入一段代码:

代码如下:

<script src="/plus/autoindex.php" language="javascript"></script>

然后点击后台生成,更新首页,到此就ok了啊.
