else语句否在php中访问如果语句

我正在为站点编写日志脚本，除了验证mysqli查询之外，我有大部分工作正在工作，其他语句未被访问，我无法弄清楚如何解决它，下面的代码是具有html，然后是所调用的PHP脚本的索引页面，所有的php验证工作除了验证所有输入字段匹配数据库字段的脚本位，我可以得到验证方的if语句工作，它将我发送到相关页面，问题是如果if语句的第一部分中的验证显示无效，那么它不会传递给else语句，我得到的只是一个空白页面，它与进行验证的php页面相同，而不是我需要的页面。非常感激任何的帮助。else语句否在php中访问如果语句

这是代码段出现问题***********

$results = $mysqli->query("SELECT * FROM signed_up WHERE email = '$email'");  

    while($row = $results->fetch_assoc()) { 


     if ($row["name"] == $name && $row["email"] == $email && $row["password"] == $password) { 
    $regErr = 'User Already Exsists!<br>Please Login'; 
    $_SESSION['regErr'] = $regErr; 
    header('location: ../login.php'); 

    } else { 

    //if ($emailErr == '' && $passwordErr == '' && $password_matchErr == '' && $email_exsistErr =='') { 
    echo '15'; 
      $_SESSION['emailErr'] = $emailErr; 
      $_SESSION['passwordErr'] = $passwordErr; 
      $_SESSION['confirm_passwordErr'] = $confirm_passwordErr; 
      $_SESSION['email_exsistErr'] = $email_exsistErr; 
    header('Location: ../join.php'); 
    exit(); 
     } 
      } 
     } 
    //} 
    ?>

编辑后的代码现在正常******************** ***

$results = $mysqli->query("SELECT * FROM signed_up WHERE email = '$email'");  

while($row = $results->fetch_assoc()) { 


    if ($row["name"] == $name && $row["email"] == $email && $row["password"] == $password) { 

$regErr = 'User Already Exsists!<br>Please Login';

为什么你比较密码检查用户是否存在？ – 2015-02-07 14:06:45

我只是验证数据库字段的每一个输入，我知道它不necassary，我可能会删除之前，生活 – Tiny 2015-02-07 14:21:27

直接把你的验证到SQL

$results = $mysqli->query("SELECT count(*) FROM signed_up WHERE email = '$email' AND name = '$name'"); 
if ($result->fetchColumn()){ 
    echo "User already exists"; 
}else{ 
    echo "New user"; 
}
