Getting Started

Please take note that Bootstrap used in this tutorial are hosted so you need internet connection for them to work.

Creating our Database

1. Open phpMyAdmin.
2. Click databases, create a database and name it as crop.
3. After creating a database, click the SQL and paste the below codes. See image below for detailed instruction.

  1. CREATE TABLE `images` (
  2. `imageid` INT(11) NOT NULL AUTO_INCREMENT,
  3. `location` VARCHAR(200) NOT NULL,
  4. `date_added` datetime NOT NULL,
  5. PRIMARY KEY(`imageid`)
  6. ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

database insert

Creating our Output Folder

Next, we create a new folder and we're gonna name it upload. This will be our output folder for uploaded images.

index.php

This is our index which contains our upload form.

  1. <?php
  2. $folder = 'upload/';
  3. $or_w = 500;
  4.  
  5.  
  6. if(isset($_POST['upload'])){
  7. $image = $_FILES['image']['tmp_name'];
  8. $filename = basename($_FILES['image']['name']);
  9.  
  10. list($width, $height) = getimagesize($image);
  11. $or_h = ($height/$width)* $or_w;
  12.  
  13. $src = imagecreatefromjpeg($image);
  14. $tmp = imagecreatetruecolor($or_w, $or_h);
  15. imagecopyresampled($tmp, $src, 0, 0, 0, 0, $or_w, $or_h, $width, $height);
  16. imagejpeg($tmp, $folder.$filename);
  17.  
  18. imagedestroy($tmp);
  19. imagedestroy($src);
  20.  
  21. $filename = urlencode($filename);
  22. header('location:crop.php?file='.$filename);
  23. }
  24.  
  25. ?>

save.php

This is our PHP code in saving the cropped images.

  1. <?php
  2.  
  3. $file = $_GET['file'];
  4.  
  5. $location = 'upload/'.$file;
  6. $newFile = time().'_'.$file;

  8.  
  9. $targ_w = $targ_h = 250;
  10.  
  11. $img_r = imagecreatefromjpeg($location);
  12. $dst_r = ImageCreateTrueColor( $targ_w, $targ_h );
  13.  
  14. imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
  15. $targ_w,$targ_h,$_POST['w'],$_POST['h']);
  16.  
  17. imagejpeg($dst_r, 'upload/'.$newFile);
  18.  
  19. //connection
  20. $conn = new mysqli('localhost', 'root', '', 'crop');
  21.  
  22. $sql="insert into images (location, date_added) values ('$newloc', NOW())";
  23. $conn->query($sql);
  24.  
  25. header('location:view.php');
  26.  
  27. ?>

view.php

This contains our images table.

  27. $query=$conn->query($sql);
  28. while($row=$query->fetch_array()){
  29. ?>
  30. <tr>
  31. <td><a href="<?php echo $row['location']; ?>"><img src="<?php echo $row['location']; ?>" width="30px" height="30px" class="thumbnail"></td>
  32. <td><?php echo $row['location']; ?></td>
  33. <td><?php echo date('M d, Y h:i A', strtotime($row['date_added'])); ?></td>
  34. </tr>
