I have some custom posts types (events) with an archive page with user controlled filtered taxomonies, - genre, event type. region.
If the user filters by say "Spoken Word" they see all "Spoken word" events - they can then click to see an individual CPT template for that posts.
I want to add a 'Back to listings' link. If I simply link to the archive page then its fine but what would be better would be a link back to the archive with the applied filter or search result the user had last set - in this case 'Spoken Word'
javascript:history.go(-1) doesnt work for example but essentially a similar concept but cross platform compliant
What are your settings for browser history management at Toolset > Settings > Front-end content?
If you have enabled "Enable history management setttings for AJAX custom search" then it should be possible to use the browser history API: hidden link
I haven't tried it recently enough to be sure that it works, but it should. Can you try that and let me know how you get on?
