织梦首页调用随机文章实现自动更新的功能
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:
- {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.
- <?php
- function sp_input( $text )
- {
- $text = trim( $text );
- $text = htmlspecialchars( $text );
- if (!get_magic_quotes_gpc())
- return addslashes( $text );
- else
- return $text;
- }
- $autotime = 3600;
- $fpath = "../data/last_time.inc";
- include( $fpath );
- if( emptyempty($last_time))
- $last_time = 0;
- if( sp_input($_GET['renew'])=="now")
- $last_time = 0;
- if((time()-$last_time)>=$autotime )
- {
- define('DEDEADMIN', ereg_replace("[/\\]{1,}",'/',dirname(__FILE__) ) );
- require_once(DEDEADMIN."/../include/common.inc.php");
- require_once(DEDEINC."/arc.partview.class.php");
-
- $templet = “tnbjh/index.htm”;
- $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, '?>' );
- 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:
<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.
