ok so I've currently sorted this out using raw PHP and mySQL queries but it feels like a hack and I'd like to Drupalafy it if possible. not sure if it would be quicker or not, but would certainly be easier to manage in the long run.
I have a list of node thumbs on a front page, ordered into Tax based groups. Click any of these and you are taken to that nodes page and you can next/previous though all the other nodes in that Tax group. there is also a link to take you back out to the front page (of which there could be many, as this is based on a higher level tax term).
I'll try and show an example.
Tax top 1.
tax sub 1
tax sub 2
Tax top 2
tax sub 3
tax sub 4
nodes 1,2,3 are in Tax sub 1
nodes 7,8,9 are in Tax sub 2
nodes 4,5,6 are in Tax sub 3
Main page 1 shows nodes 1,2,3 under heading Tax Sub 1, and 7,8,9 under Tax Sub 2,
main page 2 shows nodes 4,5,6 only under heading Tax Sub 3.
Click though to a node say 5, and you will have a
Next take you to node 6
Previous to node 4
Home/back to Main page 2.
hope that makes senese. you can see it in action on this site. www.martynazoltaszek.com
So my question is can I do this using I guess Views? I've tried but cannot elicit the control I want completely.
edit: the nodes can be in any sort order so I guess I require the nid to be carried though to the view of a single node, and from that work out what would be next previous.
