<?php
//检查数据
/* Connectint,selecting database */
$link=mysql_connect(\'localhost\',\'root\',\'lizhaoyi\')
or die("Could not connect:".mysql_error());
//echo "Connected successfully";
mysql_select_db("db_testsystem") or die("Could not select database");
if($_POST[\'login\']==\'\' or $_POST[\'name\']==\'\' or $_POST[\'id\']==\'\'or $_POST[\'password\']==\'\'or $_POST[\'repassword\']==\'\'
or $_POST[\'sex\']==\'\'or $_POST[\'address\']==\'\'){
echo "字段不可空白";
exit;
}
if($_POST[\'password\']!=$_POST[\'repassword\']){
echo "两次输入的密码不相同，请重新输入";
exit;
}
$sqlstr="insert into tb_admin values(\'".$_POST[\'login\']."\',\'".$_POST[\'name\']."\',\'".$_POST[\'id\']."\',\'".$_POST[\'password\']."\',
\'".$_POST[\'sex\']."\',\'".$_POST[\'address\']."\',now(),\'1\')";
//组合sql
$result=mysql_query($sqlstr,$link);

//echo "Connected successfully";
mysql_select_db("db_testsystem") or die("Could not select database");


$sqlstr="select * from tb_admin where adm_login=
(select par_descript from tb_parameter where par_id=
(select max(par_id) from tb_parameter));";
mysql_query("SET NAMES GB2312");
$result=mysql_query($sqlstr,$link);
/*if(!$result){die("Valid result!");}
echo "<table>";
echo "<tr><td>登录账户</td><td>用户姓名</td><td>身份证号"*/
$row=mysql_fetch_array($result,MYSQL_BOTH);
if(mysql_num_rows($result)==1){
echo ("<h1 align=center>用户注册成功，您的注册信息如下</h1>");
echo ("<p align=center>登录账户:<font color=blue>".$row[1]."</font></p>");
echo ("<p align=center>用户姓名:<font color=blue>".$row[2]."</font></p>");
