In this tutorial we will create a Upload Image Only using PDO. This code can only upload image file to the database server through PDO query when the user submit the form inputs. The code use a PDO query to upload an image file only to the database server. This is a user-friendly kind of program, feel free to use it and apply it to your system.

We will be using PDO as a query scripting it an acronym for PHP Data Objects. It is a lean, clean, and consistent way to access databases. This means developers can write portable code much easier.

Getting started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html.

And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating Database

Open your database web server then create a database name in it db_pdo_only_image, after that click Import then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepadd++, etc..). Then just copy/paste the code below then name it conn.php.

  1. <?php
  2. $conn = new PDO('mysql:host=localhost;dbname=db_pdo_only_image', 'root', '');
  3.  
  4. if(!$conn){
  5. die("Error: Failed to connect to database!");
  6. }
  7. ?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into you text editor, then save it as index.php.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
  6. </head>
  7. <body ng-app="myModule" ng-controller="myController">
  8. <nav class="navbar navbar-default">
  9. <div class="container-fluid">
  10. <a class="navbar-brand" href="<a href="https://sourcecodester.com">Sourcecodester</a>
  11. " rel="nofollow">https://sourcecodester.com">Sourcecodester</a>
  12. </a> </div>
  13. </nav>
  14. <div class="col-md-3"></div>
  15. <div class="col-md-6 well">
  16. <h3 class="text-primary">PHP - Upload Image Only Using PDO</h3>
  17. <hr style="border-top:1px dotted #ccc;">
  18. <div class="col-md-4">
  19. <form method="POST" enctype="multipart/form-data" action="upload.php">
  20. <div class="form-group">
  21. <label>Upload here</label>
  22. <input name="image" type="file" class="form-control" required="required"/>
  23. </div>
  24. <center><button class="btn btn-primary" name="upload">Upload</button></center>
  25. </form>
  26. </div>
  27. <div class="col-md-8">
  28. <table class="table table-bordered">
  29. <thead class="alert-info">
  30. <tr>
  31. <th>Image</th>
  32. <th>Image Located</th>
  33. </tr>
  34. </thead>
  35. <tbody>
  36. <?php
  37. require_once 'conn.php';
  38.  
  39. $sql = "SELECT * FROM `image`";
  40. $query = $conn->prepare($sql);
  41. $query->execute();
  42.  
  43. while($fetch = $query->fetch()){
  44. ?>
  45.  
  46. <tr>
  47. <td><?php echo $fetch['image_name']?></td>
  48. <td><?php echo $fetch['location']?></td>
  49. </tr>
  50.  
  51. <?php
  52. }
  53. ?>
  54. </tbody>
  55. </table>
  56. </div>
  57. </div>
  58. </body>
  59. </html>

Creating the Main Function

This code contains the main function of the application. This code will upload an image when the button is clicked. To do that write these block of codes inside the text editor and save it as upload.php.

  1. <?php
  2. require_once 'conn.php';
  3.  
  4. if(ISSET($_POST['upload'])){
  5. $file_name = $_FILES['image']['name'];
  6. $file_temp = $_FILES['image']['tmp_name'];
  7. $allowed_ext = array("jpg", "jpeg", "gif", "png");
  8. $exp = explode(".", $file_name);
  9. $ext = end($exp);
  10. $path = "upload/".$file_name;
  11. if(in_array($ext, $allowed_ext)){
  12. if(move_uploaded_file($file_temp, $path)){
  13. try{
  14. $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  15. $sql = "INSERT INTO `image`(image_name, location) VALUES ('$file_name', '$path')";
  16. $conn->exec($sql);
  17. }catch(PDOException $e){
  18. echo $e->getMessage();
  19. }
  20.  
  21. $conn = null;
  22. header('location: index.php');
  23. }
  24. }else{
  25. echo "<center><h3 class='text-danger'>Only image format can be upload</h3></center>";
  26. }
  27. }
  28. ?>

There you have it we successfully created a Upload Image Only using PDO. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!!!
