私はすでに試しましたが、nodbodyが助けてくれたので、もう一度試してみます。このスクリプトに登録したい人のために、制限を 16 に設定したいと思います。だれかが MY スクリプトを編集してここに投稿してください。コピーして貼り付けることができます。コーディングがかなり苦手なので、試してみると常にエラーが発生する前にplz誰かが単に私のコードをlimt 16で投稿してください。

ここにスクリプトがあります

スクリプトを複雑にする理由.ユーザーが追加するたびに単純なカウンターを使用して1を追加し、16になったら追加するスクリプトを停止するだけです

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, $header);
     header('Location: '.$success_page);
     exit;
   }
 }

else
 {
   echo "not inserted";
 }

ユーザー数の制限を設定する場合は、以下のコードを記述します。 

$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;
   }
 }

   echo "not inserted";
