标签： php mysql limit registration max

正如我已经尝试但是nodbody帮助了我，我将再次尝试。对于想要注册这个脚本的人，我想设置一个限制为16可以请某人编辑我的脚本并将其发布在这里，这样我就可以复制粘贴它，因为我在编写时非常糟糕，所以在我尝试之前总是出错PLZ有人只是简单地发布我的代码16。感谢你们，如果有人这样做会很棒

这是脚本

<?php
$error_message = "";
if ($_SERVER['REQUEST_METHOD'] == 'POST')

   $action = isset($_POST['action']) ? $_POST['action'] : '';
   $mysql_server = 'X';

为什么你的脚本很复杂。只要用户使用简单的计数器就可以添加1       添加，当它变为16时，只需停止脚本添加

即可

示例：

if(counter != 16)
{
 if (empty($error_message))
      {
     $counter++;
     $crypt_pass = md5($newpassword);
     $sql = "INSERT `".$mysql_table."` (`username`, `password`, `fullname`, `email`, `active`) VALUES ('$newusername', '$crypt_pass', '$newfullname', '$newemail', 1)";
     $result = mysql_query($sql, $db);
     mysql_close($db);
     $mailto = $newemail;
     $subject = 'X';
     $message = 'X';
     $message .= "\r\nX";
     $message .= "\r\n ";
     $message .= "\r\nTeam name for the upcoming tournament: ";
     $message .= $newusername;
     $message .= "\r\nYour password: ";
     $message .= $newpassword;
     $message .= "\r\n ";
     $message .= "\r\n ";
     $message .= "\r\nX";
     $message .= "\r\nX";
     $header  = "From: X"."\r\n";
     $header .= "Reply-To: X"."\r\n";
     $header .= "MIME-Version: 1.0"."\r\n";
     $header .= "Content-Type: text/plain; charset=utf-8"."\r\n";
     $header .= "Content-Transfer-Encoding: 8bit"."\r\n";
     $header .= "X-Mailer: PHP v".phpversion();
     mail($mailto, $subject, $message, $header);

如果要设置用户数限制，请在下面编写代码。 

$sql = "select count(*) as tot from $mysql_table";
    $rs = mysql_query($sql);
    $row = mysql_fetch_assoc($rs);
    $counter = $row['tot'];


if(counter != 16)
{
 if (empty($error_message))
      {
     $counter++;
     $crypt_pass = md5($newpassword);
     $sql = "INSERT `".$mysql_table."` (`username`, `password`, `fullname`, `email`, `active`) VALUES ('$newusername', '$crypt_pass', '$newfullname', '$newemail', 1)";
     $result = mysql_query($sql, $db);
     mysql_close($db);
     $mailto = $newemail;
     $subject = 'X';
     $message = 'X';
     $message .= "\r\nX";
     $message .= "\r\n ";
     $message .= "\r\nTeam name for the upcoming tournament: ";
     $message .= $newusername;
     $message .= "\r\nYour password: ";
     $message .= $newpassword;
     $message .= "\r\n ";
     $message .= "\r\n ";
     $message .= "\r\nX";
     $message .= "\r\nX";
     $header  = "From: X"."\r\n";
     $header .= "Reply-To: X"."\r\n";
     $header .= "MIME-Version: 1.0"."\r\n";
     $header .= "Content-Type: text/plain; charset=utf-8"."\r\n";
     $header .= "Content-Transfer-Encoding: 8bit"."\r\n";
     $header .= "X-Mailer: PHP v".phpversion();
     mail($mailto, $subject, $message, $header);
     header('Location: '.$success_page);
     exit;
   }
 }

else
 {
   echo "not inserted";
 }
