一、页面表单提交到另一页面

fixed php
<html>
<head><title>Workflow System</title></head>
<body>
<h1>Register for an Account:</h1>
<form action="registration_action.php" method="POST">

Username: <input type="text" name="name" /><br />
Email: <input type="text" name="email" /><br />
Password: <input type="password" name="pword[]" /><br />
Password (again): <input type="password" name="pword[]" /><br />

<input type="submit" value="GO" />

</form>

</body>
</html>

registration_action.php
<html>
<body>
<p>You entered:</p>

<?php
//$username = $_POST['name'];
//$password = $_POST['pword'];

//echo "<p>Username = " . $username . "</p>";
//echo "<p>Password[1] = " . $password[0] . "</p>";
//echo "<p>Password[2] = " . $password[1] . "</p>";

function validate($allSubmitted){

$message = "";

$passwords = $allSubmitted['pword'];
$firstPass = $password[0];
$secondPass = $password[1];
$username = $allSubmitted['name'];

echo "<p>Username = " . $username . "</p>";
echo "<p>Password[1] = " . $firstPass . "</p>";
echo "<p>Password[2] = " . $secondPass . "</p>";

if ($firstPass != $secondPass) {
      $message = $message."Passwords don't match<br />";
}
if (strlen($username) < 5 || strlen($username) > 50){
      $message = $message."Username must be between 5 and 50 characters<br />";
}

if ($message == ""){
      $message = "OK";
}

return $message;

}
if (validate($_POST) == "OK") {
      echo "<p>Thank you for registering!</p>";
} else {
      echo "<p>There was a problem with your registration:</p>";
      echo validate($_POST);
      echo "<p>Please try again.</p>";
}

?>

</body>
</html>
　　在registration_action.php当中

　　$firstPass = $password[0];$secondPass = $password[1];  没有找到数据；

　　fixed.php
　　二、页面表单录入数据库

　　该表单也是和上面的fixed.php中差不多，多出部分是della表单中的元素；

login.php
1

<html>
2<head><title>Workflow System</title></head>
3<body>
4<h1>Register for an Account:</h1>
5<form action="registration_action.php" method="POST">
6
7name: <input type="text" name="name" /><br />
8ID: <input type="text" name="id" /><br />
9Password: <input type="password" name="pword[]" /><br />
10Password (again): <input type="password" name="pword[]" /><br />
11msn: <input type="text" name="msn" /><br />
12address: <input type="text" name="address" /><br />
13intruduction: <input type="text" name="intruduction" /><br />
14school: <input type="text" name="school" /><br />
15birthday: <input type="text" name="birthday" /><br />
16<input type="submit" value="GO" />
17</form>
18
19</body>
20</html>
21

registration_action2.php
1<html>
2<body>
3 <p>You entered:</p>
4
5<?php
6 $username = $_POST['name'];
7 $password = $_POST['pword'];
8 $id = $_POST['id'];
9 $birthday = $_POST['birthday'];
10 $msn = $_POST['msn'];
11 $address = $_POST['address'];
12 $intruduction = $_POST['intruduction'];
13 $school = $_POST['school'];
14
15 echo "<p>Username = " . $username . "</p>";
16 echo "<p>Password[1] = " . $password[0] . "</p>";
17 echo "<p>Password[2] = " . $password[1] . "</p>";
18 echo "<p>ID= " . $id . "</p>";
19 echo "<p>birthday = " . $birthday . "</p>";
20 echo "<p>msn = " . $msn . "</p>";
21 echo "<p>address = " . $address . "</p>";
22 echo "<p>intruduction = " . $intruduction . "</p>";
23 echo "<p>school = " . $school . "</p>";
24
25
26
27function db_connect($user='root',
28                   $password='zdndd', $db='shop'){
29
30  mysql_connect('localhost', $user, $password)
31    or die('I cannot connect to db: ' . mysql_error());
32    mysql_select_db($db);
33
34}
35    db_connect();
36
37    $sql = "insert into della (name, address, school, id, birthday, msn, intruduction) values
38       ('".$username."', '".$address."', '".$school."', '".$id."', '".$birthday."', '".$msn."', '".$intruduction."')";
39       $result = mysql_query($sql);
40
41       if ($result){
42          echo "It's entered!";
43       } else {
44          echo "There's been a problem: ".mysql_error();
45       }
46?>
47</body>
48</html>
49　　1.函数 db_connect 当中的$user='root',$password='zdndd', $db='shop' 都是我phpmyadmin中的用户名、密码、shop数据库；
　　2.$sql = "insert into della (name, address, school, id, birthday, msn, intruduction) values della是一个数据库表,本来这里不是della的，不写肯定是要报错的了，还要我够聪明看到了phpmyadmin当中的SQL语言，哇哈哈！搞定！
