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: ".$password;}else {echo "输入错误";}?> 3. php代码（第二种写法 test.php）：
<?phprequire_once 'dbTest.php'; class Class_A{function Class_A(){$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）
<?phpclass Class_B{function runValue(){$valueArray = array();$valueArray["userName"] = "wang";$valueArray["password"] = "123456";return $valueArray;}}?> ４．连接数据库进行用户登录信息验证（ test.php）
<?phprequire_once 'dbTest.php'; class Class_A{function Class_A(){$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）
<?phprequire_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(); }} ?>
