php获取表单数据
1. html代码：<html>
<head>
<script language="javascript" type="text/javascript" >
function doCheck(){
if(document.formLogin.userName.value == ""){
alert("ユーザ名を入力してください");
return false;
}
if(document.formLogin.password.value == ""){
alert("パスワードを入力してください");
return false;
}
}
</script>
</head>
<body>
<form name="formLogin" action="test.php" method="post">
ユーザ名 ：<input type="text" name="userName"><br>
パスワード：<input type="text" name="password"><br><br>
<input type="submit" value="提交">
</form>
</body>
</html>
2. php代码（test.php）：
<?php
$userName = $_POST['userName'];
$password = $_POST['password'];
if($userName == "wang" && $password == "123456")
{
echo "ユーザ名：".$userName;
echo "<br>";
echo "パスワード: ".$password;
}
else {
echo "输入错误";
}
?>
3. php代码（第二种写法 test.php）：
<?php
require_once 'dbTest.php';
class Class_A{
function Class_A(){
$userName = $_POST['userName'];
$password = $_POST['password'];
$class_B = new Class_B();
$array1 = $class_B->runValue();
if($userName == $array1["userName"] && $password == $array1["password"])
{
echo "ユーザ名：".$array1["userName"];
echo "<br>";
echo "パスワード: ".$password;
}
else {
echo "输入错误";
}
}
}
$a = new Class_A();
?>
3.2（dbTest.php）
<?php
class Class_B{
function runValue(){
$valueArray = array();
$valueArray["userName"] = "wang";
$valueArray["password"] = "123456";
return $valueArray;
}
}
?>
４．连接数据库进行用户登录信息验证（ test.php）
<?php
require_once 'dbTest.php';
class Class_A{
function Class_A(){
$userName = $_POST['userName'];
$password = $_POST['password'];
$class_B = new Class_B();
$bool = $class_B->Uservalidate($userName,$password);
if($bool)
{
echo "ユーザ名：".$userName;
}
else {
echo "誤り入力します";
}
}
}
$a = new Class_A();
?>
4.2 （dbTest.php。 如果登录用户存在返回true,否则返回false）
<?php
require_once 'connect.php';
class Class_B{
public $sql = "SELECT * FROM luser ";
public $result;
function userValidate($userName, $password){
$bool;
$conn = new ConnectDatabase();
$conn->getConnectDatabase();
$this->result = mysql_query($this->sql." where name='".$userName."'");
//将查询结果放入数组中
$arrays = mysql_fetch_array($this->result);
//因为就一条数据，所以就直接从数组拿到用户名和密码
if($arrays["name"] == $userName && $arrays["password"] == $password){
$bool = true;
}
else {
$bool = false;
}
//关闭数据库连接和释放资源
$conn->mysqlClose($this->result);
return $bool;
}
}
?>
4.3(connect.php 。获得数据库的连接）
<?php
class ConnectDatabase{
function getConnectDatabase(){
$conn = mysql_connect("localhost","root",null) or die('getconnect：'.mysql_error());
mysql_select_db("sourcecodecheck") or die("sourcecodecheck: ".mysql_error());
}
function mysqlClose($result){
mysql_free_result($result);
mysql_close();
}
}
?>
