Go to Previous/Next Album (Gallery App)?

I know it's possible to output links for previous and next image, within an album (https://docs.grabaperch.com/addons/gallery/page-functions/perch-gallery-adjacent-images/).

But is it possible to output links to previous and next album?

Yes - how are you determining the current album at that point?

Thanks for the reply, Drew. I wasn't sure if it was in the documentation and I was just missing it.

I have created a page for each album and each page has this code, depending on what category I am trying to display, ie: Birds:

perch_gallery_album_listing(array( 'template'=>'list.html', 'image'=>true, 'filter'=>'category', 'match'=>'eq', 'value'=>'Birds' ));

Ok, so when you're displaying one album and need to determine the next, what code are you using to display the album?

This code in a "details.php" file:

$opts = array('template'=>'item.html');
perch_gallery_album(perch_get('item'), $opts);

$current_album = perch_gallery_album(perch_get('item'), array(
                    'skip-template'=>true
                ));

// Next album
perch_gallery_albums(array(
    'sort' => 'albumOrder',
    'sort-order' => 'ASC',
    'count' => 1,
    'filter' => 'albumOrder',
    'match' => 'gt',
    'value' => $current_album['albumOrder']
    ));

// Previous album
perch_gallery_albums(array(
    'sort' => 'albumOrder',
    'sort-order' => 'DESC',
    'count' => 1,
    'filter' => 'albumOrder',
    'match' => 'lt',
    'value' => $current_album['albumOrder']
    ));

I added this code to my details.php but I receive a "undefined function perch_gallery_albums()" error on page load.

Were you meaning for me to add it there (or am I showing my clear lack of knowledge here)?

Which version of Gallery are you using?

2.8.2 - would the changes/fixes in 2.8.4 and 2.8.5 have any effect on the perch_gallery_albums() function?

That function should already be present, so the error indicates something wrong with your installation. Updating would be a wise move.

Strange. Everything else works fine and the website has been up for months. I will have to leave it for now. Thank you for your help.
