In your Radiant installation (wherever that is), find the app directory, in which there should be a behaviors directory. For example, if you installed radiant in /home/dave/foo/radiant-0.5.2, you should put the 00_next_previous_behavior.rb in /home/dave/foo/radiant-0.5.2/app/ behaviors/.

FWIW, the problem wasn't that current.siblings was returning null.
Rather, the problem was that current.siblings returns a list that
doesn't include the current page [1], so siblings.index(current) was
returning null. Calling "self_and_siblings" instead of "siblings"
works fine. Here's the corrected version:
class Behavior::Base
define_tags do
tag "next" do |tag|
current = tag.locals.page
by = tag.attr['by'] || 'title'
siblings = current.self_and_siblings.sort_by { |page|
page.attributes[by] }
index = siblings.index(current)
next_page = siblings[index + 1]
if next_page
tag.locals.page = next_page
tag.expand
end
end
tag "previous" do |tag|
current = tag.locals.page
by = tag.attr['by'] || 'title'
siblings = current.self_and_siblings.sort_by { |page|
page.attributes[by] }
index = siblings.index(current)
previous = siblings[index - 1]
if previous
tag.locals.page = previous
tag.expand
end
end
end
end

Re: [Radiant] Next and Previous Articles
Ok, I think I have it here. Not as elegant as John's, but for some reason current.siblings returns an empty array. I simply found the page's parent and then the children, those are siblings, right? I am sure there is a better way to do this, but here is the code: tag "next_page" do |tag| current = tag.locals.page parent = tag.locals.page.parent by = tag.attr['by'] || 'title' siblings = parent.children.sort_by { |page| page.attributes[by] } index = siblings.index(current) next_page = siblings[index + 1] if next_page tag.locals.page = next_page tag.expand end end tag "prev_page" do |tag| current = tag.locals.page parent = tag.locals.page.parent by = tag.attr['by'] || 'title' siblings = parent.children.sort_by { |page| page.attributes[by] } index = siblings.index(current) prev_page = siblings[index - 1] if prev_page tag.locals.page = prev_page tag.expand end endStill has a few problems, like showing the last link on the first page, but these are easily overcome.Keith BingmanOn Aug 23, 2006, at 9:04 AM, Keith Bingman wrote:John, I am having a few problems with this.

The definition for next should be:
tag "next" do |tag|
current = tag.locals.page
by = tag.attr['by'] || 'title'
siblings = current.siblings.sort_by { |page| page.attributes[by] }
index = siblings.index(current)
next = siblings[index + 1]
if next
tag.locals.page = next
tag.expand
end

Something like this might work for you:
Behavior::Base.define_tags do
tag "next" do |tag|
current = tag.locals.page
siblings = current.siblings.sort_by { |page| page.title }
index = siblings.index(current)
next = siblings[index + 1]
if next
tag.locals.page = next
tag.expand
end
end
tag "previous" do |tag|
current = tag.locals.page
by = tag.attr['by'] || 'title'
siblings = current.siblings.sort_by { |page| page.attributes[by] }
index = siblings.index(current)
previous = siblings[index - 1]
if previous
tag.locals.page = previous
tag.expand
end
end
end
This would enable you to do something like this:
Or even:

The above is completely untested.

Am I overlooking something, or as it currently stands is it impossible to create links the next article (next Child, in this case)? I need to create something like this for a small part of a site, which is basically done. This is the last thing holding me up...
