Question

好的，这是我第一次在这个网站上提问，但是我走了。所以即时通讯学习如何创建登录等。我正在观看一个视频，他做了一行代码，由于某种原因，我做了同样的事情而且没有用。如果有人能提供帮助那就太棒了。

代码：

<?php
 if ($_POST['loginbtn']){
          $user = $_POST['user'];
          $password = $_POST['password'];

          if($user){
             if($password){

                require("../testing/dbconfig.php");

                //encrypt password
                $password = md5(md5("a4v".$password."weed"));
                //verify user is real
                $query = mysql_query("SELECT * FROM user WHERE username='$user'");
                $numrows = mysql_num_rows($query);
                if($numrows == 1){

                   $row = mysql_fetch_assoc($query);

                   $dbid = $row['id'];
                   $dbuser = $row['username'];
                   $dbpass = $row['password'];
                   $dbactive = $row['active'];

                   if ($password == $dbpass){
                       if($dbactive == 1){

                          //allowing users session
                          $_SESSION['userid'] = $dbid;
                          $_SESSION['username'] = $dbuser;


                          echo "Logged in as <b>$dbuser</b>. Please wait while you are redirected.";
                       }
                       else
                          echo "This account has not been activated. Please contact admin if you think this is a problem.";
                   }
                   else
                      echo "The password that was entered was invalid. Please check spelling.";
                }
                else
                    echo "Username was not valid. Please check spelling and try again";

                mysql_close();
          }
          else
               echo "<center style='font-size:32px; color:red;'>You must have a set Password/center>";
          }
          else
               echo "<center style='font-size:32px; color:red;'>You must have a set Username</center>";
      }
      else
           echo "<center style='font-size:32px; color:red;'>Waiting for login requests....</center>";

＆GT;

现在错误就是在这里拍摄

$numrows = mysql_num_rows($query);
                if($numrows == 1){

                   $row = mysql_fetch_assoc($query);

                   $dbid = $row['id'];
                   $dbuser = $row['username'];
                   $dbpass = $row['password'];
                   $dbactive = $row['active'];

收到结束时出错

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /srv/disk10/1954442/www/satan.cf/testing/login.php on line 56 Username was not valid. Please check spelling and try again
