  html, mysql, php

I have to upload an image into the folder and path into the database.
this is the code below.

<form action="load.php" method="post">
<input type="file" name="image" accept=".jpg,.png">
<input type="submit" name="submit">

$image = "";
if (isset($_POST['submit'])) {
 $image = $_FILES['image']['name'];
