Загрузка переменной в базу данных

Я загружаю картинку на сервер. Но как я могу поместить ее еще и в базу данных? INSERT, что я использую ниже не срабатывает. То есть, запись не происходит. В чем может быть ошибка?

<?php
if(isset($_POST['save'])){
$conn = mysqli_connect("localhost", "root", "", "my-db2");
    $path="/var/www/myshop33.ru/bootstrap/users_images/";
    $name = $_FILES['imageupload']['name'];//Name of the File
    $temp = $_FILES['imageupload']['tmp_name'];
    if(move_uploaded_file($temp, $path . $name)){
        echo "success";

    $query = "INSERT INTO customers(userfile) VALUES ('" . $name . "')";
    $result = mysqli_query($conn, $query);
    }else{
        echo "failed";
    }
}
?>
<form method="post" action="" enctype="multipart/form-data">
    <input type="file" name="imageupload">
    <input type="submit" name="save" value="submit">
</form>


<form method="post" action="profile.php" class="form-row">
        <div class="col-md-3 text-center">
            <img class="img-responsive img-thumbnail " src="./bootstrap/users_images/<?php echo $name; ?>">
           </div>
</form>

UPD:

<?php
if(isset($_POST['save'])){
    require_once "./functions/database_functions.php";
    require "./template/header.php";
    $conn = db_connect();

    $path="/var/www/myshop33.ru/bootstrap/users_images/";
    $userfile = $_FILES['imageupload']['name'];//Name of the File
    $temp = $_FILES['imageupload']['tmp_name'];
    if(move_uploaded_file($temp, $path . $userfile)){
        echo "success";

    require_once("./functions/database_functions.php");

    $customer = getCustomerIdbyEmail($_SESSION['email']);
        $id=$customer['id'];
    $query="UPDATE customers set 
    userfile='$userfile' where id='$id'";
        mysqli_query($conn, $query);
    }
}
?>
<form method="post" action="" enctype="multipart/form-data">
    <input type="file" name="imageupload">
    <input type="submit" name="save" value="submit">
</form>

<form method="post" action="profile.php" class="form-row">
        <div class="col-md-3 text-center">
            <img class="img-responsive img-thumbnail " src="./bootstrap/users_images/<?php echo $userfile; ?>">
           </div>
</form>

UPD 2: download_img.php

<?php
ini_set('display_errors',1);
error_reporting(E_ALL ^E_NOTICE);
error_reporting(E_ALL);
if(isset($_POST['save'])){
    require_once "./functions/database_functions.php";
    require "./template/header.php";
    $conn = db_connect();

    $path="/var/www/myshop33.ru/bootstrap/users_images/";
    $userfile = $_FILES['imageupload']['name'];//Name of the File
    $temp = $_FILES['imageupload']['tmp_name'];
    if(move_uploaded_file($temp, $path . $userfile)){
    header("Location: profile.php");

    require_once("./functions/database_functions.php");

    $customer = getCustomerIdbyEmail($_SESSION['email']);
        $id=$customer['id'];
    $query="UPDATE customers set 
    userfile='$userfile' where id='$id'";
        mysqli_query($conn, $query);
    }
}
?>

UPD 2: profile.php

<?php
    session_start();
    require_once "./functions/database_functions.php";
    $title = "Profile";
    require "./template/header.php";
    // connect database
    if(isset($_SESSION['email'])){
    $customer = getCustomerIdbyEmail($_SESSION['email']);
?>

<form method="post" action="download_img.php" enctype="multipart/form-data">
    <input type="file" name="imageupload">
    <input type="submit" name="save" value="submit">
    <input type="submit" name="delete" value="delete">
</form>

<form method="post" action="profile.php" class="form-row">
        <div class="col-md-3 text-center">
            <img class="img-responsive img-thumbnail " src="./bootstrap/users_images/<?php echo $customer['userfile']; ?>">
           </div>
</form>
