General Support: ZIP Support - Almost there (with a little help)

Hello,

We need ZIP upload capability on our site so I followed the instructions to add the ZIP library /lib/pclzip-2-4, and added the code in Changeset 323 (with a slight modification). The ZIP function almost works:

-I can select a zip file, create a new album, and start uploading the file, but
-I am redirected to a page with a heading root/trunk/lib/pclzip-2-4/pclzip.lib.php at the midpoint of the page.

The code in the plog-upload.php file was changed as follows:
The first change was to add the zip extension to $allowed_exts = array("jpg", "bmp", "gif", "png","zip");
The second change was to add the code between the // START/END BG ADD headings. Any help to debug the problem would be appreciated.

Thanks,

Brian

Code from updated plog-upload.php file:

$allowed_exts = array("jpg", "bmp", "gif", "png","zip");

if ($_FILES["userfile"]["name"] == ""){
$output .= '<p class="errors">No file name specified!</p>';
}

// BEGIN BG ADD Changeset 323 code
[the first line below is not the same as 323 code but matches the code elsewhere in the 2.1 script which has no $pi variable]
else if ($filename_ext == "zip") {
// let's decompress the zip file into the uploads folder and then redirect
// the user to plog-import.php
include('../lib/pclzip-2-4/pclzip.lib.php');

//zip file to extract
$archive = new PclZip($_FILES["userfile"]["tmp_name"]);

//extract to uploads folder
if ($archive->extract(PCLZIP_OPT_REMOVE_ALL_PATH, PCLZIP_OPT_PATH,$config["basedir"].'uploads/') == 0)
{

//failed
$output .= '<p class="errors">Error:'.$archive->errorInfo(true).'</p>';
}
else
{
// unzip succeeded, let's redirect to the import interface.
header("location:plog-import.php?directory=bda1146671668d77b2da21c84146056a");
}
}
// END BG ADD Changeset 323 code

else if (!in_array($filename_ext, $allowed_exts))
{
$output .= '<p class="errors">Not a valid image file!</p>';
}
