The session cookie for signing in and for forms, the cookies that keep your design and language, and the cookie that keeps this choice. They stay on because the website needs them; you can delete them in your browser settings at any time.
Google Analytics, loaded through Google Tag Manager (GTM-MPGWKTQV), counts visits and shows us which pages are read: the pages you open, the page you came from, your browser, device and screen size, and your approximate location derived from your IP address. Google processes the data for us and may transfer it to the USA. It sets the cookies _ga and _ga_* for up to 2 years. Off until you turn it on; when you turn it off again, Google is no longer loaded and these cookies are deleted.

P. Renaud ·
It doesn't work with nodes.
Before : <ul> {foreach $all_related_albums as $related_album} <li>{$related_album.main_node.node_id}</li> {/foreach} </ul> {def $unique_related_albums=$all_related_albums|unique()} After : <ul> {foreach $unique_related_albums as $related_album} <li>{$related_album.main_node.node_id}</li> {/foreach} </ul>produces the following output :
You have to build an intermediate array with node id's, then use unique, then re-fetch all nodes...
