最近搭建一個(gè)帝國(guó)CMS的整站源碼，自帶的數(shù)據(jù)可能是采集的，以前的簡(jiǎn)介字段內(nèi)容只截取了60個(gè)字，感覺簡(jiǎn)介60字符太少了，不美觀，想讓簡(jiǎn)介都截取200個(gè)字，怎么批量修改呢，文章太多了手動(dòng)改肯定不行，網(wǎng)上查了下帝國(guó)CMS教程。
分享一段可用代碼。
帝國(guó)CMS批量提取正文內(nèi)容到簡(jiǎn)介方法
1、先備份數(shù)據(jù)庫(kù)
2、保存以下代碼到 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'];
}
$b or exit('轉(zhuǎn)換結(jié)束！');
echo "<meta http-equiv=\"refresh\" content=\"1;url=ChangeByID.php?startid=".$b."\">";
echo "已轉(zhuǎn)換ID".$b;
db_close();
$empire=null;
?>3、瀏覽器訪問ChangeByID.php
