That’s quite unusual.

Do the gallery displays work, or is it only albums that are coming out blank?

Thanks for your report! I’ve committed a fix that should fix your problem; we recently made an update that broke nggdb::get_gallery()’s search by slug. I can’t say exactly when this will be released (but we do hope it will be soon), if you’d like to upgrade to .76 you can fix this by altering nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/lib/ngg-db.php and replacing line 125’s $image_mapper->select()->where(array("galleryid = %d", $id)); with

if (is_numeric($id))
    $image_mapper->select()->where(array("galleryid = %d", $id));
else
    $image_mapper->select()->where(array("slug = %s", $id));

PS we should be fixing soon in a point release, the results of $nggdb->get_gallery() should always be a C_Image_Wrapper.

We’ve been slowly replacing some of our older methods with a more extensible framework for NextGen 2.0+: it looks like in this case we turned one of our legacy methods into a wrapper that doesn’t return exactly the right thing.

Could you try one of the following:
1) insert $storage = C_Gallery_Storage::get_instance(); above your call to $nggdb->get_gallery()
2) insert $image->imageURL = $storage->get_image_url($image, 'full'); as the first line in your foreach()

OR

1) change foreach($gallery as $image) to foreach($gallery as $dbimg) and add $image = new C_Image_Wrapper($dbimg); first thing in the foreach()? That should provide the same attributes to the $image object you would expect from $nggdb->get_gallery()

The numbers are generated in nextgen-gallery/products/photocrati_nextgen/modules/dynamic_thumbnails/class.dynamic_thumbnails_manager.php in get_name_from_params()

The following code will retrieve the gallery & image and then give you the path to the image full URL, a dynamicly generated clone, and the official thumbnail:

<?php

$dynthumbs      = C_Dynamic_Thumbnails_Manager::get_instance();
$gallery_mapper = C_Gallery_Mapper::get_instance();
$image_mapper   = C_Image_Mapper::get_instance();

$gallery = $gallery_mapper->find($gallery_id);
if (!empty($gallery->previewpic) {
    $image = $image_mapper->find($gallery->previewpic);
    $dynamic_parameters = array(
        'width'  => '100',
        'height' => '100',
        'quality' => '100',
        'crop' => TRUE,
        'watermark' => FALSE
    );
    $thumbnail_size_name = $dynthumbs->get_size_name($dynamic_parameters);
    $full_url    = $storage->get_image_url($image, 'full');
    $dynamic_url = $storage->get_image_url($image, $thumbnail_size_name, TRUE);
    $thumb_url   = $storage->get_image_url($image, 'thumb');
}

I hope that helps!

I have to apologize, this isn’t provided by the theme at all but is a feature of NextGen I’d forgotten about.

You should be able to add the following to the end of your theme’s functions.php (regardless of theme):

add_filter('the_title', 'fix_ngg_title', 10, 3);
function fix_ngg_title($title, $id)
{
    preg_match('/^Images tagged "(.*)"$/', $title, $matches);
    if (!empty($matches))
    {
        return "Foobar: {$matches[1]}";
    }
    return $title;
}

Where $matches[1] will have the tag name.

In future releases I’ll try to make this easier or more direct to filter. I hope this helps!

This is a bit more difficult than it used to be because NextGen can now display multiple galleries together. What you would want to do is this:

$imap = C_Image_Mapper::get_instance();
$gmap = C_Gallery_Mapper::get_instance();
$storage = C_Gallery_Storage::get_instance();
foreach ($gallery->displayed_gallery->container_ids as $id) {
    $image = $imap->find($gmap->find($id)->previewpic);
    var_dump($image);
    var_dump($storage->get_image_url($image, 'thumb'));
    var_dump($storage->get_image_url($image, 'full'));
}

That will display the image information itself followed by the URL to its thumbnail and the fullsize version.

I hope that helps!

The gallery ID shouldn’t change on every page load, only if you change the settings to that gallery.

Are you using a shortcode or the Attach-To-Post window, or is your gallery a ‘random’ one?
