我正在使用 PHP表单生成器提供的PHP注册脚本。有很多过时的代码，所以我必须进去修复它。
我的问题是，我创建的第一个测试用户工作得很好，但我创建的所有其他测试用户最终都有一个未知的数组作为密码。
这是代码：
<?php
include("http://wolffwebdesign.co.cc/php/global.inc.php");
$errors=0;
$error="The following errors occured while processing your form input.<ul>";
$FirstName = mysql_real_escape_string($_POST['FirstName']);
$MiddleInitial = mysql_real_escape_string($_POST['MiddleInitial']);
$LastName = mysql_real_escape_string($_POST['LastName']);
$Company = mysql_real_escape_string($_POST['Company']);
$Email = mysql_real_escape_string($_POST['Email']);
$Username = mysql_real_escape_string($_POST['Username']);
$Password = $_POST['Password'];
$resultuser = mysql_query("SELECT Username FROM members WHERE Username = '$Username'");
$resultpass = mysql_query("SELECT Password FROM members WHERE Password = '$Password'");
if($FirstName=="" || $LastName=="" || $Company=="" || $Email=="" || $Username=="" || $Password=="" ){
$errors=1;
$error.="<li>You did not enter one or more of the required fields. Please go back and try again.</li>";
}
if(!preg_match('/^[a-z\d_\.\-]+@([a-z\d\-]+)(?:\.(?1))+$/i',$Email)){
$error.="<li>Invalid email address entered</li>";
$errors=1;
}
$regex = '~([^A-Z0-9]+)~i'
if(!preg_match($regex, $Username) || !preg_match($regex, $Password)) {
$errors.="<li>Invalid Username or Password entered</li>";
$errors=1;
}
if($errors==1) {
echo $error;
}
if(mysql_num_rows($resultuser) == 1){
die("<li>That Username exists already</li>");
}
if(mysql_num_rows($resultpass) == 1){
die("<li>That password exists already</li>");
}
else{
if($remember == 1)
{$expire=time()+50400;
setcookie("extendedloginwwd", $Username, $expire);
}
elseif($remember == 0)
{$expire=time()+50400;
setcookie("loginwwd", $Username, $expire);
}
mkdir("home/wolffweb/www/$Username", 0755);
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));
mail( "wolffswebdesign@gmail.com", "New User Submission", "Name: $LastName, $FirstName, $MiddleInitial\nCompany: $Company\nEmail: $Email\nUsername: $Username\nPassword: $password\nFolder: $dirname\nErrors?: $error\n", "From: Sign Up <newuser@wolffwebdesign.x10.mx>" );
$link = mysql_connect("localhost","wolffweb_admin","jl10101");
mysql_select_db("wolffweb_users",$link);
$query="insert into members (First_Name,Middle_Initial,Last_Name,Company,Email,Username,Password) values ('".$FirstName."','".$MiddleInitial."','".$LastName."','".$Company."','".$Email."','".$Username."','".$Password."')";
mysql_query($query);
$make=fopen("admin/data.dat","a");
$to_put="";
$to_put .= $FirstName."|".$MiddleInitial."|".$LastName."|".$Company."|".$Email."|".$Username."|".$Password."
";
fwrite($make,$to_put);
}
?>
这是显示的内容：
<!-- This is the content of the Thank you page, be careful while changing it -->
<h2>Thank you!</h2>
<table width=50%>
<tr>
<td>
First Name:
</td>
<td>
<?php echo $FirstName; ?>
</td>
</tr>
<tr>
<td>
Middle Initial:
</td>
<td>
<?php echo $MiddleInitial; ?>
</td>
</tr>
<tr>
<td>
Last Name:
</td>
<td>
<?php echo $LastName; ?>
</td>
</tr>
<tr>
<td>
Company:
</td>
<td>
<?php echo $Company; ?>
</td>
</tr>
<tr>
<td>
Email:
</td>
<td>
<?php echo $Email; ?>
</td>
</tr>
<tr>
<td>
Username:
</td>
<td>
<?php echo $Username; ?>
</td>
</tr>
<tr>
<td>
Password:
</td>
<td>
<?php echo $Password; ?>
</td>
</tr>
</table>
<!-- Do not change anything below this line -->
<?php
{}
?>
例如，如果我将密码 hello52 设置为<?php echo $Password; ?>，而且在MYSQL数据库中密码最终为 Array ，这时候我将 Array 插入登录表单我收到错误的密码错误。我的假设是密码最终成为某种随机数组。有什么方法可以解决这个问题吗？

以下是表单代码：

我也在使用mkdir（）函数，因为我希望每个用户都有自己的目录，其中包含一个服务页面，目录没有被创建，有没有办法解决这个问题？

答案 0 :(得分：1)
if(!preg_match('~([^A-Z0-9]+)~i', $Username, $Password)) {
$errors.="<li>Invalid Username or Password entered</li>";
$errors=1;
}
上面的代码将preg_match('~([^A-Z0-9]+)~i', $Username)数组传递给$ Password
尝试：
$regex = '~([^A-Z0-9]+)~i'
if(!preg_match($regex, $Username) || !preg_match($regex, $Password)) {
$errors.="<li>Invalid Username or Password entered</li>";
$errors=1;
}
