PHP 提交表单，然后保存数据库示例：
1.sql脚本：
create database company;
use company;
create table employee(
id int(11) not null primary key auto_increment,
emp_name varchar(20) not null,
emp_no varchar(30) not null,
emp_job varchar(50)
);
2.index.php代码：
?php
header("Content-type:text/html;charset=utf-8;");
//判断是否提交表单
if(isset($_POST['btn'])){
//连接数据库
$conn=mysql_connect("localhost","root","root");
if(!$conn){
die("数据库连接错误！".mysql_error());
}
mysql_select_db("company");
mysql_query("set names utf8");
//获取表单提交元素
$emp_name=$_POST['emp_name'];
$emp_no=$_POST['emp_no'];
$emp_job=$_POST['emp_job'];
//验证表单元素，然后入库操作
if($emp_name $emp_no $emp_job){
$sql="insert into employee
(emp_name,emp_no,emp_job)
values
('{$emp_name}','{$emp_no}','{$emp_job}')
";
$int=mysql_query($sql);
$suc_msg="font color='green'数据插入成功! /fonta href='javascript:history.go(-1);' 返回 /a";
$err_msg="数据插入失败";
exit ($int?$suc_msg:$err_msg);
}else{
exit ("提交数据全部为必填项！");
}
}

3.运行效果：
把下面的代码保存为post.php
?
$conn = mysql_connect("localhost","11111","22222");
$action = $_POST['action'];
if($action == 'send'){
$username = $_POST['username'];
$password = $_POST['password'];
mysql_select_db("333333",$conn);
$sql = "INSERT INTO player (username,password) VALUES ('$username','$password')";
$result = mysql_query($sql,$conn);
}
