最近接到一个帝国cms模板改版项目,自带的数据可能是采集的,以前的简介字段内容只截取了60个字,新模板的简介60字符太少了,不美观,想让简介都截取200个字,怎么批量修改呢,文章太多了手动改肯定不行,网上查了下帝国cms教程。分享一段可用代码。
帝国CMS批量提取正文内容到简介方法
1、先备份数据库
2、保存e/admin/ChangeByID.php
<?php define('EmpireCMSAdmin','1'); require("../class/connect.php"); require("../class/db_sql.php"); require("../class/functions.php"); require LoadLang("pub/fun.php"); require("../class/t_functions.php"); require("../data/dbcache/class.php"); require("../data/dbcache/MemberLevel.php"); $link=db_connect(); $empire=new mysqlquery(); $tbname="news"; $sid=(int)$_GET['startid']; $b=0; $rs=$empire->query("SELECT id,newstext FROM {$dbtbpre}ecms_{$tbname}_data_1 WHERE id>{$sid} limit 20"); while($r=$empire->fetch($rs)) { $smalltext=''; !$r['newstext'] or $smalltext=SubSmalltextVal($r['newstext'],200); $smalltext=addslashes($smalltext); $smalltext && $empire->query("UPDATE {$dbtbpre}ecms_{$tbname} SET smalltext='{$smalltext}' WHERE id=".$r[id]); $b=$r['id']; } $b or exit('转换结束!'); echo "<meta http-equiv="refresh" content="1;url=ChangeByID.php?startid=".$b."">"; echo "已转换ID".$b; db_close(); $empire=null; ?>
3、浏览器访问ChangeByID.php
