PHP Update Image In MySQL

We have already a tutorial for PHP Insert Image In MySQL and PHP Deleting Image In MySQL. So, I decided to create a follow-uo tutorial for PHP Update Image In MySQL. In this tutorial, we are going to update the current Image to a new one. For this tutorial, we are going to use the UPDATE Statement to update the current image in our table. Let's start with: This is the image that we are going to edit. Result

Updating Image

Modal Form Field

<div id="delete<?php  echo $id;?>" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<h3 id="myModalLabel">Update</h3>
</div>
<div class="modal-body">
<div class="alert alert-danger">
<?php if($row['image_location'] != ""): ?>
<img src="uploads/<?php echo $row['image_location']; ?>" width="100px" height="100px" style="border:1px solid #333333; margin-left: 30px;">
<?php else: ?>
<img src="images/default.png" width="100px" height="100px" style="border:1px solid #333333; margin-left: 30px;">
<?php endif; ?>
<form action="edit_PDO.php<?php echo '?tbl_image_id='.$id; ?>" method="post" enctype="multipart/form-data">
<div style="color:blue; margin-left:150px; font-size:30px;">
        <input type="file" name="image" style="margin-top:-115px;">
</div>
</div>
<hr>
<div class="modal-footer">
<button class="btn btn-inverse" data-dismiss="modal" aria-hidden="true">No</button>
<button type="submit" name="submit" class="btn btn-danger">Yes</button>
</form>
</div>
</div>
</div>

Creating Our Database

<?php 
$conn = new PDO('mysql:host=localhost; dbname=upload_image','root', ''); 
?>

Creating Our UPDATE Statement

<?php
 
require_once ('db.php');
 
$get_id=$_REQUEST['tbl_image_id'];
 
move_uploaded_file($_FILES["image"]["tmp_name"],"uploads/" . $_FILES["image"]["name"]);                 
$location1=$_FILES["image"]["name"];
 
 
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE tbl_image SET image_location ='$location1' WHERE tbl_image_id = '$get_id' ";
 
$conn->exec($sql);
echo "<script>alert('Successfully Updated!!!'); window.location='index.php'</script>";
?>

Output:

Modal Form Result
