NextGen Gallery Custom Field Rotating Images

NextGen Gallery Custom Field Rotating Images was created by us about 5 years ago for Ultimate Fiji Vacations. Since then the NextGen gallery has gone through some major changes. It has been taken over by Imagely and it has had some major upgrades.

Shortcode Changes

Some of these NextGen Gallery plugin changes were also shortcode changes. And these caused a not loading or not loading of some galleries (old post on setup) of a client of ours. We had to dig deep into the code changes to figure out what to do. We realized templates were loaded differently and that also the shortcode to load a gallery had changed. It now calles source and container_ids to load a gallery with images properly. The code

$gal = apply_filters('the_content', '[nggallery id='.$gal.' ' . $nggtemplate. ']' );
is therefore no longer applicable.

Full Code

Here is the full code to now load the gallery based on custom post type ID:
/* NG Gallery Custom Field Rotating Images */ 
$gallery = get_post_meta($post->ID, 'Gallery ID Number', true); 
$gal = $gallery; 
if( !empty($gal) ) { 
$gal = apply_filters('the_content', '[ngg_images source="galleries" container_ids=' .$gal.' display_type="photocrati-nextgen_basic_imagebrowser"]');
echo $gal;
}

As you can see the source=”” has been added and we removed the old fashioned way loading of the template as it no longer worked.

Template Loading

As the template is no longer loaded the old fashioned way and as this code allowed it to be loaded right away we decided do ditch loading a template by absolute path like so:

template="/home/user/domain.com/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/view/imagebrowser.php"

Instead we added the necessary JavaScript for the styling in the code where the slider was generated. This saved us the loading of another file and worked just as well!
