I am trying to make login function which it takes two arguments username and password but when I check and use this function on login.php file if any value has returned from this function but it do not give me anything.

this is post request and all login file

 <?php 

    include "inc/header.php";

    include "inc/functions.php";



    if($_SERVER['REQUEST_METHOD'] == 'POST') {

        if(isset($_POST["admin_login"])) {



            $username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);

            $password = filter_input(INPUT_POST, 'password', FILTER_SANITIZE_STRING);



            $admin = get_admin_login($username, $password);



            if(! session_id()){

                session_start();

            }

            if(! empty($admin)) {

                if($admin['username'] == $username) {

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

                        $_SESSION['msg'] = "Welcome Again " . $username;

                        redirect("index.php");

                    }else {

                        $_SESSION['error_msg'] = "Wrong Password";

                        redirect("login.php");

                    }

                }else {

                    $_SESSION['error_msg'] = "Wrong Username";

                    redirect("login.php");  

                }

            }else {

                $_SESSION['error_msg'] = "Wrong Login, Check your Username and Password";

                redirect("login.php");      

            }

        }

    }

?>





<div class="login-alerts">

<?php if(! session_id()) {

        session_start();

    }

    if(! empty($_SESSION['error_msg'])) {

        echo "<div class='alert alert-danger'>";

        echo $_SESSION['error_msg'];

        echo "</div>";

        $_SESSION['error_msg'] = "";

    }

    if(! empty($_SESSION['msg'])) {

        echo "<div class='alert alert-success'>";

        echo $_SESSION['msg'];

        echo "</div>";

        $_SESSION['msg'] = "";

    }

?>

</div>

<div class="form">

    <div class="form-header">

        <h3 class="text-center">Welcome to <span style="color: #b30b0b">Z</span>Blog</h3>

    </div>

    <div class="form-body">

        <form class="form" action="login.php" method="POST" >

            <div class="form-group">

                <span class=""></span>

                <input type="text" name="username" class="form-control" placeholder="Username" required autocomplete="off" >

            </div>

            <div class="form-group">

                <span class=""></span>

                <input type="password" name="password" class="form-control" placeholder="Password" required autocomplete="off">

            </div>

            <div class="form-group">

                <input style="float: right;" type="submit" name="admin_login" class="btn btn-default" value="Login" >

                <a href="" style="float: left;">Forgot your password?</a>

            </div>

        </form>

    </div>



</div>



<?php include "inc/footer.php"; ?>

function

function get_admin_login($username, $password) {

include "connect.php";

$sql = "SELECT id, username, password FROM admins WHERE username = ? && password = ? ";

try {

    $result = $con->prepare($sql);

    $result->bindValue(1,$username, PDO::PARAM_STR);

    $result->bindValue(2,$password, PDO::PARAM_STR);



    $result->execute();

    return $result->fetchAll(PDO::FETCH_ASSOC);

}catch(Exception $e) {

    echo "Error: ". $e->getMessage(). "n";

    return false;

}

}

It always gives me this error ( Wrong Login, Check your Username and Password )
which means that $admin is empty. thanks
