mysql_select_db("数据库名");
写入数据：mysql_query("insert
into
表名
(字段1，字段2)
values
("数据1","数据2")");
你的问题太含糊，只能给你这个答复，不明白再追问。
$rs
=
mysql_query($sql);
这一段改成：
if(mysql_query($sql)){
echo
"script
language=JavaScriptalert('数据库提交成功！');window.location.href='team.php';/script";
}else{
echo
"插入失败，错误原因是{mysql_error()}";
}
然后根据错误原因解决问题，或者把错误原因给大家看看。
如果仍然提示成功，请检查你的权限，还有你的mysql数据库Team这个表里的主键有没有重复？
?php
// 以 MySQL 为例:
mysql_connect('127.0.0.1', 'root', 'root', 3306); // 连接数据库
mysql_select_db('test'); // 选择数据库
mysql_query('set names utf8'); // 执行SQL
// 插入数据语句
$sql = "INSERT INTO table (username, password) VALUES ('Jack@163.com', '123456')";
$r = mysql_query($sql);
if (mysql_affected_rows()) {
echo '新增成功';
} else {
echo mysql_error();
}
PHP向MySQL数据库中写入数据有三个步骤：
1，PHP和MySQL建立连接关系
2，打开MySQL数据库
3，接受页面数据，PHP录入到指定的表中
1、2两步可直接使用一个数据库链接文件即可：conn.php
代码如下
?php
mysql_connect("localhost","root","");//连接MySQL
mysql_select_db("hello");//选择数据库
?
当然，前提是已经安装WEB服务器、PHP和MySQL，并且建立MySQL表“cnbruce”
mysql_connect()中三个参数分别为MySQL地址、MySQL用户名和MySQL密码
然后就是通过WEB页面传递数据，让PHP通过SQL语句将数据写入MySQL数据库指定的表中，比如新建文件 post.php
代码如下
?php
require_once("conn.php");//引用数据库链接文件
$uname = $_GET['n'];//GET方法为URL参数传递
$psw = $_GET['p'];
$psw=md5($psw);//直接使用MD5加密
$sql = "insert into members(username,password) values ('$uname','$psw')";
mysql_query($sql);//借SQL语句插入数据
mysql_close();//关闭MySQL连接
echo "成功录入数据";
?
测试页面： ;p=i0514
即可向MySQL数据库hello的members表中插入新的数据“cnbruce”到username字段、“i0514”到password字段
补充：读取表
读取表中的内容,这里我们用while,可以根据具体情况,用for 或其他的.
代码如下
while($row = mysql_fetch_array($result))
{
echo "div style="height:24px; line-height:24px; font-weight:bold;""; //排版代码
echo $row['Topic'] . "br/";
echo "/div"; //排版代码

1：首先要使用PHP的超全局变量 $_GET 和 $_POST 用于收集表单数据（form-data）
2：然后使用INSERT INTO 语句用于向数据库表中插入新记录。
具体示例：
（1）首先创建了一个名为 "Persons" 的表，有三个列："Firstname", "Lastname" 以及 "Age"。
?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
mysql_query("INSERT INTO Persons (FirstName, LastName, Age)
VALUES ('Peter', 'Griffin', '35')");
mysql_query("INSERT INTO Persons (FirstName, LastName, Age)
VALUES ('Glenn', 'Quagmire', '33')");
mysql_close($con);
?
（2）其次创建一个 HTML 表单，这个表单可把新记录插入 "Persons" 表。
html
body
form action="insert.php" method="post"
Firstname: input type="text" name="firstname" /
Lastname: input type="text" name="lastname" /
Age: input type="text" name="age" /
input type="submit" /
/form
/body
/html
（3）接着当用户点击上例中 HTML 表单中的提交按钮时，表单数据被发送到 "insert.php"。"insert.php" 文件连接数据库，并通过
$_POST 变量从表单取回值。然后，mysql_query() 函数执行 INSERT INTO 语句，一条新的记录会添加到数据库表中。
?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
$sql="INSERT INTO Persons (FirstName, LastName, Age)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "1 record added";
mysql_close($con)
