ログインリダイレクト用のスイッチステートメントの適切な配置

Question

PHPについてはまだまだアマチュアです。私は、システムにユーザをログインさせるために使用しているPHPコードのログインリダイレクトを設定しようとしています。今のところ、私はswitch文とPHPの両方を完成させました。

テーブルにuser、password、groupIDの列があります。

ありがとうございました！

<?php 
$con=mysqli_connect("localhost", "user", "pass", "dbname"); 
//"localhost", "userName" is username; "Password" is password; "dbName" is DB_Name; 
if (mysqli_connect_errno($con)) 
{ 
    echo "MySql Error: " . mysqli_connect_error(); 
    } 

$query=mysqli_query($con,"SELECT * FROM login WHERE UserName='$_POST[UserName]' && Password='$_POST[Password]' && GroupID='$_POST[GroupID]'"); 
$count=mysqli_num_rows($query); 
$row=mysqli_fetch_array($query); 

if ($count==1) 
{ 
    session_start(); 
    $_SESSION['UserName'] = $_POST['UserName']; 
    $_SESSION['Password'] = $_POST['Password']; 
    $_SESSION['GroupID'] = $_POST['GroupID']; 
    //header("location: http://localhost/wordpress/test-page/"); 
    } 
else 
{ 
    echo "Invalid username or password"; 
    } 

mysqli_close($con); 
?> 

switch文：？

<?php 

$GroupID = $_POST['GroupID']; 


switch($GroupID){ 
    case '1': 
     header("Location: http://localhost/wordpress/portal1/"); 
     } else 
    case '2': 
     header("Location: http://localhost/wordpress/portal2/"); 
    case '3': 
    // If GroupID = 3 Redirect to correct page 
     header("Location: http://localhost/wordpress/portal3/"); 
    default: 
    // If GroupID does not match set user groups redirect to error page 
     header("Location: couldNotDirect_ContactAdmin.html"); 
}

これを試してみてください。

<?php 
$con=mysqli_connect("localhost", "user", "pass", "dbname"); 
//"localhost", "userName" is username; "Password" is password; "dbName" is DB_Name; 
if (mysqli_connect_errno($con)) 
{ 
    echo "MySql Error: " . mysqli_connect_error(); 
    } 

$query=mysqli_query($con,"SELECT * FROM login WHERE UserName='$_POST[UserName]' && Password='$_POST[Password]' && GroupID='$_POST[GroupID]'"); 
$count=mysqli_num_rows($query); 
$row=mysqli_fetch_array($query); 

if ($count==1) 
{ 
    session_start(); 
    $_SESSION['UserName'] = $_POST['UserName']; 
    $_SESSION['Password'] = $_POST['Password']; 
    $_SESSION['GroupID'] = $_POST['GroupID']; 
    switch($_POST['GroupID']){ 
     case '1': 
      header("Location: http://localhost/wordpress/portal1/"); 
      break; 
    case '2': 
     header("Location: http://localhost/wordpress/portal2/"); 
     break; 
    case '3': 
    // If GroupID = 3 Redirect to correct page 
     header("Location: http://localhost/wordpress/portal3/"); 
     break; 
    default: 
    // If GroupID does not match set user groups redirect to error page 
     header("Location: couldNotDirect_ContactAdmin.html"); 
     break;`enter code here` 
} 
    } 
else 
{ 
    echo "Invalid username or password"; 
    } 

mysqli_close($con); 
?>
