如何在 php 中使用引导模式显示通知

Question

I would like to replace echo "<script>alert('User is Logged In');</script>";我想替换echo "<script>alert('User is Logged In');</script>"; with echo "<script>$('#modalNotification').modal()</script>"; echo "<script>$('#modalNotification').modal()</script>"; in php, But it does not shows up in my browser.在 php 中，但它没有出现在我的浏览器中。

The coding is shown below:编码如下图所示：

<?php 

    include('config/connect_database.php');

    $Username = '';

    if(isset($_POST['Login'])) {

        $Username = mysqli_real_escape_string($conn, $_POST['Username']);
        $Password = mysqli_real_escape_string($conn, $_POST['Password']);

        $sql = "SELECT Username, Password, Authority FROM user WHERE Username LIKE '$Username' AND Status LIKE 'Active'";

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

        if(mysqli_num_rows($result) > 0) {
            $username = mysqli_fetch_assoc($result);

            mysqli_free_result($result);
            mysqli_close($conn);

            if(($Username === $username['Username']) && (password_verify($Password, $username['Password']))) {
                //echo "<script>alert('User is Logged In');</script>";
                echo "<script>$('#modalNotification').modal()</script>";

                session_start();
                $_SESSION['Username'] = $_POST['Username'];
                $_SESSION['Authority'] = $username['Authority'];

                echo "<script>location.href = 'home.php';</script>";
            } else {
                echo "<script>alert('Invalid Username or Password');</script>";         
            }
        } else {
            echo "<script>alert('Invalid Username or Password');</script>";     
        }   

    }
