Previous/Next (Back/Forward) links for entity and other pages, that allow to visit them in a sequence.
Unlike with the existing back/forward module, the sequence of items (entities etc) is not based on a view, but on hierarchical information already present in your site.
- It provides a configurable block with prev/next links based on menu trees.
The block is named "Treewalk Prev/Next (Menu)"
- It provides Display suite fields with prev/next links based on entityreference / taxonomy_term_reference fields.
The ds fields are named as "Treewalk Prev/Next (...)".
Example: Taxonomy + nodes
A structure with taxonomy and nodes:
term 1 - node 1.a + term 1.1 - node 1.1.a + term 1.2 - node 1.2.a - node 1.2.b term 2 - node 2.a - node 2.b + term 2.1 - node 2.1.a - node 2.1.b + term 2.1.1 + term 2.1.2 + term 2.2 + term 2.3
The module produces two back/forward sequences: One for nodes, another for terms.
Example 2: "parent node" entityreference (untested)
We need to model the book with an entity reference, where each node links to its parent.
book page 1 book page 2 + book page 2.1 + book page 2.2 + book page 2.2.1 book page 3 + book page 3.1
The module can produce back/forward links for those book pages, in sequence as above. (ok, this is still in development, but the architecture is designed to make this possible)
Example 3: Menu tree (book-like)
menu link 1 + menu link 1.1 menu link 2 + menu link 2.1 + menu link 2.2
Back/Forward links will be produced with a sequence as above. The links will be exposed as block, because we are no longer dealing with entities.
Difference to Previous/Next API
We found that the hierarchical sort can not be easily modeled with Previous/Next API.
Also, we wanted a solution that works for entities other than nodes. We use the module for products on product/%, in combination with Commerce product page.
Unlike Previous/Next API, we do not cache or index anything. Instead, we have queries that just run fast enough :)
Create your hierarchy of taxonomy terms, and tag some nodes or other entities with this vocabulary.
Every TaxonomyTermReference, no matter which entity type, will create a prev/next field in the ds field settings. There you can specify the label for prev/next, and you are done.
This module still needs work on making the ordering customizable.
Also, some features are not yet implemented as advertised - but the architecture does allow for it.
