这是我写的一个登录处理程序。用户名和密码都存在于我的数据库中。当我尝试登录时，出现错误。PHP中出现错误登录

这是我的base.php代码：

?php 
    session_start(); 

    $host="localhost"; // Host name 
    $username="root"; //Mysql username 
    $password=""; //Mysql password 
    $db_name="kuih"; // Database name 

    //Connect to server and select database. 
    mysql_connect("$host", "$username", "$password") or die("cannot connect"); 
    mysql_select_db("$db_name") or die ("cannot select DB"); 

    ?>

这是我的index.php。

<?php include "base.php"; ?> //base.php 
      <?php 
      if(!empty($_SESSION['LoggedIn']) && !empty($_SESSION['username'])) 
      { 
       ?> 
       <h1>Member Area</h1> 
       <pThanks for logging in! You are <b><?=$_SESSION['username']?></b> and your email address is <b><?=$_SESSION['email']?></b>.</p> 
        <?php 
      } 
      elseif(!empty($_POST['username']) && !empty($_POST['password'])) 
      { 
       $username = mysql_real_escape_string($_POST['username']); 
       $password = md5(mysql_real_escape_string($_POST['password'])); 
       $checklogin = mysql_query("SELECT * FROM register WHERE username = '".$username."' AND password = '".$password."'"); 
        if(mysql_num_rows($checklogin) == 1) 
       { 
        $row = mysql_fetch_array($checklogin); 
        $email = $row['email']; 

        $_SESSION['username'] = $username; 
        $_SESSION['email'] = $email; 
        $_SESSION['LoggedIn'] = 1; 

        echo "<h1>Success</h1>"; 
        echo "<p>We are now redirecting you to the member area.</p>"; 
        echo "<meta http-equiv='refresh' content='=2;index.php' />"; 
       } 
       else 
       { 
        echo "<h1>Error</h1>"; 
        echo "<p>Sorry, your account could not be found. Please <a href=\"index.php\">click here to try again</a>.</p>"; 
       } 
      } 
      else 
      { 
       ?>

这是我的登录表单代码：

会员登录

   <p>Thanks for visiting! Please either login below, or <a href="register.php">click here to register</a>.</p> 

       <form method="post" action="index.php" name="loginform" id="loginform"> 
       <fieldset> 
        <label for="username">Username:</label><input type="text" name="username" id="username" /><br /> 
        <label for="password">Password:</label><input type="password" name="password" id="password" /><br /> 
        <input type="submit" name="login" id="login" value="Login" /> 
       </fieldset> 
       </form> 

       <?php 
      } 
      ?>

你觉得这个怎么样？谁能帮我？

添加'的print_r（$ _ SESSION）''前回声 “

错误

”'以获取调试的详细信息。 –

**旁注**不要使用'mysql _ *（）' - 它已被弃用。改为使用'mysqli _ *（）'或'PDO'。另外，如果您将它散列化，则不需要转义密码。对于SQL，MD5的输出是安全的。 – 2013-11-05 03:33:17

嗨，我使用print_r（$ _ SESSION），但仍然是相同的，帐户无法找到.. –

尝试，而不是

(mysql_num_rows($checklogin) > 0)

(mysql_num_rows($checklogin) == 1)
