帝国cms插件安装，包含数据表的生成和删除，后台管理菜单的生成和删除。
先看引导页面，代码为：
<?php
error_reporting(E_ALL ^ E_NOTICE);
@set_time_limit(10000);
define('EmpireCMSAdmin','1');
require('../../../class/connect.php');
require('../../../class/db_sql.php');
require('../../../class/functions.php');
$link=db_connect();
$empire=new mysqlquery();
$editor=2;
if($_GET['ecms']=="install")
{
$doinstall=$_GET['doinstall'];
if($doinstall=='install')//安装操作
{
include('install.php');
$word='已安装完毕!';
}
elseif($doinstall=='uninstall')//卸载操作
{
include('uninstall.php');
$word='已卸载完毕!';
}
echo"置顶插件 $word 感谢您的关注。插件定制QQ 110102296";
exit();
}
?>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<style>
a:link { COLOR: #000000; TEXT-DECORATION: none }

<script>
function CheckUpdate(obj){
if(confirm('确认操作?'))
{
obj.updatebutton.disabled=true;
return true;
}
return false;
}
</script>
</head>
<body>
<form method="GET" action="index.php" name="formupdate" onsubmit="return CheckUpdate(document.formupdate);">
<br>
<br>
<br>
<table width="500" border="0" align="center" cellpadding="3" cellspacing="1" bgcolor="#4FB4DE">

<td height="30" colspan="2"> <div align="center"><strong><font color="#FFFFFF">置顶插件安装/卸载程序</font></strong></div></td>

<td> <input type=submit name=updatebutton value="提交操作"> <input name="ecms" type="hidden" id="ecms" value="install">

</tr>
</table>
</form>
</body>
</html>然后是，安装页面，示范了数据表的建立和菜单的建立：
<?php
if(!defined('InEmpireCMS'))
{
exit();
}
if(file_exists("install.off"))
{
echo"置顶插件安装程序已锁定。如果要重新安装，请删除<b>/e/extend/zhiding/install/install.off</b>文件！";
exit();
}
//------ 插件安装 ------
//存放置顶套餐的表单
$empire->query("DROP TABLE IF EXISTS `{$dbtbpre}zhiding_taocan`");
$empire->query(SetCreateTable("
CREATE TABLE `{$dbtbpre}zhiding_taocan` (
`taocanid` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
`taocanname` varchar(50) NOT NULL DEFAULT '' COMMENT '套餐名称',
`toplong` tinyint(3) NOT NULL DEFAULT '0' COMMENT '置顶时长',
`price` float(5,2) unsigned NOT NULL DEFAULT '0.00' COMMENT '原价',
`newprice` float(5,2) unsigned NOT NULL DEFAULT '0.00' COMMENT '优惠价',
`saytext` varchar(255) NOT NULL DEFAULT '' COMMENT '套餐说明',
`jibie` int(2) unsigned NOT NULL DEFAULT '1' COMMENT '置顶级别',
PRIMARY KEY (`taocanid`)
) ENGINE=MyISAM;",$ecms_config['db']['dbchar'])
);
//置顶消费记录
$empire->query("DROP TABLE IF EXISTS `{$dbtbpre}zhiding_jilu`");
$empire->query(SetCreateTable("
CREATE TABLE `{$dbtbpre}zhiding_jilu` (
`zhidingid` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
`userid` mediumint(8) unsigned NOT NULL DEFAULT '0' COMMENT '会员id',

`riqi` int(10) unsigned NOT NULL DEFAULT '0' COMMENT '置顶日期',

`ischeck` tinyint(1) unsigned NOT NULL DEFAULT '0' COMMENT '过期检查',
PRIMARY KEY (`zhidingid`),
KEY `ischeck` (`ischeck`)
) TYPE=MyISAM;",$ecms_config['db']['dbchar'])
);
//增加插件菜单
$empire->query("insert into `{$dbtbpre}enewsmenuclass` values(NULL,'置顶管理','0','0','2','');");
$menuclassid=$empire->lastid();
$empire->query("insert into `{$dbtbpre}enewsmenu` values(NULL,'管理置顶记录','/e/extend/zhiding/batEditTable/batEditTable.php','0','$menuclassid',2);");
$empire->query("insert into `{$dbtbpre}enewsmenu` values(NULL,'管理置顶套餐','/e/extend/zhiding/showtaocan.php','0','$menuclassid',2);");
$empire->query("insert into `{$dbtbpre}enewsmenu` values(NULL,'管理百度推送','/e/extend/p2b/index.php','0','$menuclassid',2);");
//锁定安装程序
$fp=@fopen("install.off","w");
@fclose($fp);
?>卸载插件的代码则是这样的：
<?php
if(!defined('InEmpireCMS'))
{
exit();
}
//------ 插件卸载 ------
if(file_exists("install.off"))
{
echo"插件安装程序已锁定。如果要重新安装，请删除<b>/e/extend/sms/install/install.off</b>文件！";
exit();
}
$empire->query("drop table if exists `{$dbtbpre}zhiding_taocan`;");
$empire->query("drop table if exists `{$dbtbpre}zhiding_jilu`;");
//删除插件菜单
$menuclassr=$empire->fetch1("select classid from {$dbtbpre}enewsmenuclass where classname='置顶管理' limit 1");
$empire->query("delete from {$dbtbpre}enewsmenuclass where classid='$menuclassr[classid]'");
$empire->query("delete from {$dbtbpre}enewsmenu where classid='$menuclassr[classid]'");
?>
