Hello guyz,

I need some help about downloading MULTIPLE files on php. I've used while loop by checking if the checkboxes were checked but when I continued on clicking the download button, all the system downloads is just 1 file. Why is that?.. any suggestions would be appreciated. Thanks.

I've provided the codes for easier tracing (I've included two files----Upload(w/c is working fine) and the download)

<--uploadserver.php (file 1)-->
<?php
	 
	 echo $reload=$_SERVER['PHP_SELF'];

	 
?>
<form action="<?$reload?>" method="post" name="fileForm" enctype="multipart/form-data">
   File to upload:
 <table>
  <tr><td><input name="upfile" type="file"></td></tr>
  <tr><td><input type="submit" name="submitBtn" value="Upload"></td></tr>
  </table> 
</form>
<?php
if(isset($_POST['submitBtn']))
{
 if(file_exists("d:/Upload")==0)
 		echo mkdir("d:/Upload");
 $target_path="d:/Upload/";
 $x="d";
 $file_name=$_FILES['upfile']['name'];
 if(file_exists("d:/Upload/$file_name")==0)
 {
  echo '<br>Target Path: '.$target_path=$target_path.basename($_FILES['upfile']['name']).'';
  if(move_uploaded_file($_FILES['upfile']['tmp_name'], $target_path))
  {
   echo "<br>File:". basename($_FILES['upfile']['name']).' uploaded...';
   echo "<br>Working directory :".getcwd();
  }
  else
 	 echo error;

 }
  else
  	  echo "<br>Error: File duplication";
 }
 
?>
<a href="downloadserver.php"><br>Download</a>

You can only download one file per server response, because you can only send one set of response header.

If you want to download multiple, based on which checkbox values are selected, write them to a ZIP archive and return that instead.

Oh, I really thought I can download multiple files selected on checkbox at the same time by using loop. Thanks for the tip.
