Is this possible? Multiple Uploads...

[vivabensmith]

Hi!

Im trying to upload multiple images and resize them, I can get the code to work with one upload but not 2?

Any advice / help would be great.

What error messages do you get? If none, have you turned on the display of all errors to help debug?

<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);

<?php

   foreach( $_FILES as $file_name => $file_array )
   { # begin foreach

   #foreach file uploaded - do the following...

   echo "name: ".$file_array['name']."<br />\n";
   echo "type: ".$file_array['type']."<br />\n";
   echo "tmp_name: ".$file_array['tmp_name']."<br />\n";
   echo "error: ".$file_array['error']."<br />\n";
   echo "size: ".$file_array['size']."<br />\n";

   # process image...

   } # end foreach

?>

I think what you have done will work, once you set a loop to run for every upload present, that is.

Start by fixing the "$sizes" problem in the second major if block. Either just change this line...

$sizes2 = getimagesize($prod_img2);

...to this...

$sizes = getimagesize($prod_img2);

...or else change all reference to $sizes in that block to $sizes2.
