PHP Update Image In MySQL


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.

Modal Form Field

  1. <div id="delete<?php echo $id;?>" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  2. <div class="modal-header">
  3. <h3 id="myModalLabel">Update</h3>
  4. </div>
  5. <div class="modal-body">
  6. <div class="alert alert-danger">
  7. <?php if($row['image_location'] != ""): ?>
  8. <img src="uploads/<?php echo $row['image_location']; ?>" width="100px" height="100px" style="border:1px solid #333333; margin-left: 30px;">
  9. <?php else: ?>
  10. <img src="images/default.png" width="100px" height="100px" style="border:1px solid #333333; margin-left: 30px;">
  11. <?php endif; ?>
  12. <form action="edit_PDO.php<?php echo '?tbl_image_id='.$id; ?>" method="post" enctype="multipart/form-data">
  13. <div style="color:blue; margin-left:150px; font-size:30px;">
  14. <input type="file" name="image" style="margin-top:-115px;">
  15. </div>
  16. </div>
  17. <hr>

  21. </form>
  22. </div>
  23. </div>
  24. </div>

Creating Our Database

  1. <?php
  2. $conn = new PDO('mysql:host=localhost; dbname=upload_image','root', '');
  3. ?>

Creating Our UPDATE Statement

  1. <?php
  2.  
  3. require_once ('db.php');
  4.  
  5. $get_id=$_REQUEST['tbl_image_id'];
  6.  
  7. move_uploaded_file($_FILES["image"]["tmp_name"],"uploads/" . $_FILES["image"]["name"]);
  8. $location1=$_FILES["image"]["name"];
  9.  
  10.  
  11. $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  12. $sql = "UPDATE tbl_image SET image_location ='$location1' WHERE tbl_image_id = '$get_id' ";
  13.  
  14. $conn->exec($sql);
  15. echo "<script>alert('Successfully Updated!!!'); window.location='index.php'</script>";
  16. ?>

Output:
