基本注册未知错误

Question

我有这个错误

Parse error: syntax error, unexpected '{' in receive/register.php on line 1

我的receive/register.php是

<?php
$_POST['username'] = $username;
$_POST['password1'] = $password;
$_POST['password2'] = $passwordagain;
$_POST['email'] = $email;
echo $username.'<br>'.$password.'<br>'.$passwordagain.'<br>'.$email;
if (!isset($username) || !isset($password) || !isset($passwordagain) || !isset($email))
{   /*
$_SESSION['regerrorid'] = '0';
$_SESSION['regerrormsg'] = 'Not all fields are completed';
header ('Location: ./'.$directory.'register');*/
echo'uhm';
}
?>

发送信息的是

<?php
/* !!!!only if the code works
$_SESSION['regerrorid'] = $success;
$_SESSION['regerrormsg'] = $message;
*/
?>
<div class='registration-<?php echo $success; ?>'><?php echo $message; ?></div><br>
<form action="receive/register.php" method="POST">
  <span style='font-size:14px;font-family:"Lucida Console", Monaco, monospace'>Username:</span><input class='lolquired' type="text" name="username" /><br />
  <span style='font-size:14px;font-family:"Lucida Console", Monaco, monospace'>Password:</span><input class='lolquired' type="password" name="password1" /><br />
  <span style='margin-left:-56px;font-size:14px;font-family:"Lucida Console", Monaco, monospace'>Repeat Password:</span><input class='lolquired' type="password" name="password2" /><br />
  <span style='margin-left:24px;font-size:14px;font-family:"Lucida Console", Monaco, monospace'>Email:</span><input class='lolquired' type="email" name="email" /><br /><br />
  <input class="button" type="submit" value="Submit" />
</form><?php 
/* !!!!only if the code works
$_SESSION['regerrorid'] = '';
$_SESSION['regerrormsg'] = '';
*/

Answer 1

应该是:

$username = $_POST['username'];
$password = $_POST['password'];

等等……

当我使用你的代码，我得到$username是未定义的错误在php 5.3.5

也注意到…如果你使用$_SESSION，你需要添加

session_start();

在你的代码顶部
