What's wrong?
Fatal error: Call to undefined function: zip_open() in /home/myusername/public_html/chusy/pictures/zen/functions.php on line 102
Comments
However, with a little tweak to the functions.php file, I've managed to fix this by calling on the unzip utility instead.
My fix: download link
Simply backup your existing functions.php file (it's in the /zen folder) and put this one in its place.
I've only tested this on my host (I'm with Dreamhost), so I cannot promise anything to anyone, but at least since no functions are changed only added, it shouldn't break anything.
More information on substituting zip_open by unzip at http://php.net/zip_open
Also made some changes to support folders in the zip files and to exclude some hidden files (__MACOSX, .file and so on)
download link: functions.php
Thanks for the update; my own installation hasn't made it to 1.0.6 yet, but I'll try your hack as soon as I get around to upgrading.
Good luck!
P.S.
If someone remembers I was already offering to use PclZip:

You have to download the PclZip lib from the download adress above and place pclzip.lib.php into you zen-folder.. then you have to replace the unzip-function in functions.php with the following code:
`// Unzip function; ignores ZIP directory structure.
// Requires PclZip Lib
require_once(dirname(__FILE__) . "/pclzip.lib.php");
function myPreExtractCallBack($p_event, &$p_header)
{
$info = pathinfo($p_header['filename']);
if (in_array(strtolower($info['extension']), array('jpg','jpeg','gif','png'))) {
return 1;
} else {
return 0;
}
}
function unzip($file, $dir) {
$zip = new PclZip($file);
if (($list = $zip->listContent()) == 0) {
die("Error : ".$zip->errorInfo(true));
}
for ($i=0; $i
if ($zip->extract( PCLZIP_OPT_PATH, $dir,
PCLZIP_OPT_SET_CHMOD, 0777,
PCLZIP_OPT_REMOVE_ALL_PATH,
PCLZIP_CB_PRE_EXTRACT, 'myPreExtractCallBack') == 0) {
die("Error : ".$archive->errorInfo(true));
}
}
}`
Work's fine for me, have fun..

Just paste the code below into your zen/functions.php file - place it at the very end of the file, just above the closing ?> - and that's all you need. No further downloads.
```
// zip_open fix starts here
function ShellFix($s)
{
return "'".str_replace("'", "'''", $s)."'";
}
function zip_open($s)
{
$fp = @fopen($s, 'rb');
if(!$fp) return false;
$lines = Array();
$cmd = 'unzip -v '.shellfix($s);
exec($cmd, $lines);
$contents = Array();
$ok=false;
foreach($lines as $line)
{
if($line[0]=='-') { $ok=!$ok; continue; }
if(!$ok) continue;
$length = (int)$line;
$fn = trim(substr($line,58));
$contents[] = Array('name' => $fn, 'length' => $length);
}
return
Array('fp' => $fp,
'name' => $s,
'contents' => $contents,
'pointer' => -1);
}
function zip_read(&$fp)
{
if(!$fp) return false;
$next = $fp['pointer'] + 1;
if($next >= count($fp['contents'])) return false;
$fp['pointer'] = $next;
return $fp['contents'][$next];
}
function zip_entry_name(&$res)
{
if(!$res) return false;
return $res['name'];
}
function zip_entry_filesize(&$res)
{
if(!$res) return false;
return $res['length'];
}
function zip_entry_open(&$fp, &$res)
{
if(!$res) return false;
$cmd = 'unzip -p '.shellfix($fp['name']).' '.shellfix($res['name']);
$res['fp'] = popen($cmd, 'r');
return !!$res['fp'];
}
function zip_entry_read(&$res, $nbytes)
{
while ($s = fgets($res['fp'],1024)) {
$data .= $s;
}
return $data;
}
function zip_entry_close(&$res)
{
fclose($res['fp']);
unset($res['fp']);
}
function zip_close(&$fp)
{
fclose($fp['fp']);
}

As mentioned above, there's more information on substituting zip_open by unzip in this way at http://php.net/zip_open
You can download the build here: http://www.zenphoto.org/files/nightly
But we must be talking about different nightlies... Would be great if for 1.1 uploading zips works on all hosts (also those that don't offer zip_open), straight out of the box. There will be many people who sooner give up on this fine gallery than fiddle with php files.

`Fatal error: Cannot redeclare zip_open() in
I'm a bit lost in this one, so... any clue?
I am guessing that your version of PHP won't let you over ride its zip_open function. Don't know why that would be, though.
I have deactivated zip support and it is working fine without it. Maybe it would be good that someone confirms it is working ok in "zip-supported servers".
