I have a problem with this gallery: http://www.athelstonesc.com/gallery

It was working fine and it seems without changing anything something has broken it. I have since reinstalled the gallery without a change in what is happening.

The images / database are fine and the gallery index appears fine, however clicking on the individual galleries gives a blank page.

I am still able to edit the albums and upload images in admin without a problem. From the admin area i can access individual photo pages which also work fine, it's just the album index page which is not working

I have tried changing mod_rewrite without success.

I am now stumped as to the cause of this. Can you help?

Can we see the code in your album.php file?

We've seen this several times now and we still can't figure out what it is...

` <div id="gallerytitle">

<h2><span><a href="`

Is all that's printed for the album.php page, indicating the problem traces back to the `<?php echo getGalleryIndexURL();?>` call, which is the strangest thing... Let's look at all code that's called with that one call, shall we? I'm going to nail this bugger once and for all....

So, let's backtrace.

album.php:16 `getGalleryIndexURL();`

> template-functions.php:77
`function getGalleryIndexURL() {

global $_zp_current_album;

if (in_context(ZP_ALBUM) && $_zp_current_album->getGalleryPage() > 1) {

$page = $_zp_current_album->getGalleryPage();

return rewrite_path("/page/" . $page, "/index.php?page=" . $page);

} else {

return WEBPATH . "/";

}

}`

> class-album.php:279
`function getGalleryPage() {

$albums_per_page = zp_conf('albums_per_page');

if ($this->index == null)

$this->index = array_search($this->name, $this->gallery->getAlbums(0));

return floor(($this->index / $albums_per_page)+1);

}`

> class-gallery:36
` function getAlbums($page=0) {

// Have the albums been loaded yet?

if (is_null($this->albums)) {

$albumnames = $this->loadAlbumNames();

$albums = $this->sortAlbumArray($albumnames);

$this->albums = $albums;

}

if ($page == 0) {

return $this->albums;

} else {

$albums_per_page = zp_conf('albums_per_page');

return array_slice($this->albums, $albums_per_page*($page-1), $albums_per_page);

}

}`

> class-gallery.php:107
` function loadAlbumNames() {

$albumdir = $this->getAlbumDir();

if (!is_dir($albumdir) || !is_readable($albumdir)) {

die("Error: The 'albums' directory cannot be found or is not readable.");

}

$dir = opendir($albumdir);

$albums = array();

while ($dirname = readdir($dir)) {

if (is_dir($albumdir.$dirname) && substr($dirname, 0, 1) != '.') {

$albums[] = $dirname;

}

}

closedir($dir);

return $albums;

}`
> class-gallery.php:67
` function sortAlbumArray($albums) {

$albums_r = array();

$result = query("SELECT folder, sort_order FROM " . prefix("albums")

. " ORDER BY sort_order");

$i = 0;

$albums_r = array_flip($albums);

$albums_touched = array();

while ($row = mysql_fetch_assoc($result)) {

$folder = $row['folder'];

if (array_key_exists($folder, $albums_r)) {

$albums_r[$folder] = $i;

$albums_touched[] = $folder;

}

$i++;

}

$albums_untouched = array_diff($albums, $albums_touched);

foreach($albums_untouched as $alb) {

$albums_r[$alb] = $i;

$i++;

}

$albums = array_flip($albums_r);

ksort($albums);

$albums_ordered = array();

foreach($albums as $album) {

$albums_ordered[] = $album;

}

return $albums_ordered;

}`

Whew. That's all the meaningful code that gets executed with that one call... crazy. I'm posting this, then I'm going to look through it for possible problems.

I honestly can't see where the problem could lie... I'd love to be able to print debug messages along this whole path.... if you're willing to test a version like that please let me know and I'll set one up. It would be of great help to track this down for others who are experiencing this bug as well. Thank you!

I'd be happy to test a version like that for you. As for the album.php file, it's exactly as the default would be as I haven't altered it at all.

Hi, I just found zenphoto and installed it, but I too am getting this weird error. http://drull.ca/zenphoto

Has a fix for this been found yet?

Hey, I think I'm having a similar problem. It seems to have something to do with the fact that the link to the album is not actually pointing at the 'albums' directory... e.g. The link to the gallery from my front page points at '/test_gallery' instead of '/albums/test-gallery/'

I haven't looked at the code yet, but I'll post back if I get it fixed here.

Also, what is being used to make the thumbnails? Mine aren't bein displayed at all... not sure if the module is installed/enabled server side.

Thanks

Ok, I got my links pointing in the right direction by setting mod_rewrite=false in the config file. Still no thumbnails although I haven't tried creating an album since changing the setting.

OK. Just in case anyone else runs into this.... In an hour of complete retardation I forgot to add the path to my php install to the top of i.php (#!/usr/local/bin/php for my server) It probably won't affect most people, but there ya go
