    Continuing from "How to copy files from one directory and adding two supporting files into the copied directory/directories"
    We now have moved the necessary files to manage those images in the newly moved directory entitled "archive".
    There is one exception, the code below will only delete one image at a time even though multiple checkboxes can be marked for deletion. How would we modify this code (manage.php) to delete all the images that have checkboxes selected?

        <form action="remove.php" method="POST" >
            <input type="submit" name="remove" value="Select image and Delete">
      <ul>
<?php

    //define location of photo image
    $photosDir = './images';

    //define which file extention are images
    $photosExt = array('gif','jpg','jpeg','tif','tiff','bmp','png');

    //initialize array to hold filenames of images found
    $photoList = array();

    //read directory contents
    //build photo list
    if (file_exists($photosDir)) {
      $dp = opendir($photosDir) or die('Error: cannot open file');
      while ($file =  readdir($dp)) {
        if ($file != '.' && $file != '..') {
          $fileData = pathinfo($file);
          if (in_array($fileData['extension'], $photosExt)) {
            $photoList[] = "$photosDir/$file"; // file includes as an array
          }
        }
      }
      
      closedir($dp);
    }else {
      die('ERROR: directory dosent exists');
    }

    //itarate over photo list
    //display each image and file name
    if (count($photoList)>0) {
      for ($x=0; $x <count($photoList) ; $x++) {
        ?>

        <li>
		
          <input type="checkbox" name="check" value="<?php echo $photoList[$x] ?>">
		 
          <img src="<?php echo $photoList[$x]; ?>" class="imagegrid"/>
			<div>
				<?php echo 'Image Name: '.  basename($photoList[$x]); ?><br>
				<?php echo 'Image Size: '. round(filesize($photoList[$x])/1024) . 'KB'; ?>
			</div>
        </li>

        <?php
      		}
    		} else {
      		die('ERROR: No image found');
    		}

	?>
    
    </ul>
  </form>
  </body>
</html>

    and next, remove.php

    <?php 

//for delete image
  //check the image
  //unlink the file
  if (isset($_POST['check']) && !empty($_POST['check'])) {
       //find the file
      $file = $_POST['check'];
      //delete from directory
      if(is_file($file)){
          unlink($file);
          header('Location: manage.php');
          echo $_POST['check']." has successfully deleted";
      }else{
          echo $_POST['check']." has not been found!";
      }
  } else{
  	header('Location: manage.php');
    echo "Select any image for delete";
  }

 ?>

    In manage.php I would change "check" to "check[]"

    so from

     <input type="checkbox" name="check" value="<?php echo $photoList[$x] ?>">

    to

     <input type="checkbox" name="check[]" value="<?php echo $photoList[$x] ?>">

    Then in remove.php you can access all the fields that were selected by doing something like:

    $files= $_POST['check'];

foreach ($files as $file){ 
   // Do something with each $file here
}

    I have not tested this. But the idea should be solid. Keep me posted.
