使用php登录成功后如何重定向到新页面

Question

我会简短明了，因为无论发布什么内容，我似乎都被禁止了。我在这里发现了类似的问题，但是所有建议都与我的代码无关。登录成功重定向到新页面后，我只需要帮助即可。 $username = $_POST["username"];     $conn = mysqli_connect($host, $user, $pass, $db);    $query = "SELECT * FROM user WHERE username = '" .$username.  "'";    $result = mysqli_query($conn,$query);    while ($row = mysqli_fetch_assoc($result)){        echo "Password Entered: " . $_POST["password"];        echo "Correct Pasword: " . $row['password'];        // See if the password is correct        if ($_POST["password"] === $row['password'])            echo "Logon Successful!";        else {            echo "Logon Failed!";        }    }     if (!mysqli_fetch_assoc($result))        echo "Invalid Username";?>

Answer 1

我只是忘了标题后面的分号。

$query = "SELECT * FROM user WHERE username = '" .$username.  "'";

$result = mysqli_query($conn,$query);

while ($row = mysqli_fetch_assoc($result)){

    // See if the password is correct

    if  ($_POST["password"] === $row['password']){

        echo "Logon Successful!";

        header("Location: index.php"); 

        exit();

    }

Answer 2

可能会有一些变化，如下所示：

login.php

$username = $_POST["username"]; 

$password = $_POST["password"];

$conn = mysqli_connect($host, $user, $pass, $db);

$query = "SELECT * FROM user WHERE username = '" . $username .  "'";

$result = mysqli_query($conn,$query);

while ($row = mysqli_fetch_assoc($result)){

    // See if the password is correct

    if ($password === $row['password']){

        header('location: login_successful.php');

    }else {

        // you can hide the message at QueryString via SESSION or COOKIE

        header('location: login_form.php?message=FAIL_MESSAGE');  //you can detect and show login status message.

    }

}
