How can I filter by a term when on a sub-page of that term?

Question

I have a non-hierarchical taxonomy and 2 content types.

I need to make these pages with Views:

Mysite.com/something/termA/ContentTypeA
(This will display nodes of content type A that are tagged with termA.)

Mysite.com/something/termA/ContentTypeB
(This will display nodes of content type B that are tagged with termA.)

Mysite.com/something/termA/ContentTypeA
(This will display nodes of content type A that are tagged with termA.)

Mysite.com/something/termB/ContentTypeB
(This will display nodes of content type B that are tagged with termB.)

In actual fact there are a lot of terms so I need these pages to be from 1 or 2 Views (EG with dynamic filters). I cant just make 4 Views with static filters.

I could create 2 Views, one for each content type. Filtering by the content type is simple so my issue is just that I need to figure out how to filter by a term when you are on a sub page of that term, not on the term's page itself.

Eg filtering by termA on this page is easy: 
Mysite.com/something/termA/

But how do you filter by termA when on this page?
Mysite.com/something/termA/ContentTypeA

Answer 1

I'm a little confuse on what you're trying to show but I think you can do what you want with contextual filters.

To do so:

• Add taxonomy to the filter critera (Has taxonomy term ID)
• In the first section (when not available), select Provide default value
• Type : Raw Value from URL
• Select your path component (let say 2 for your term1, categories would be 1)
• In the "When the filter value IS available or a default is provided" section, check "Specify validation criteria"
• Validator : Taxonomy
• Check the appropriate vocabulatory
• Filter value type : Term name converted to ID

What that filter will do is check a part of the url and match it against the vocabulary. If a term is matched, let say term1, it will show nodes that have the term. You can add multiple filter to validate multiple part of the url. It's pretty much the same for the content types.

So /term1 could filter all node with term1. term1/activities could filter all term1&activities... You get the idea. Just don't hide the view if the filter doesn't validate, make it show all results.

Answer 2

This can be done by adding a module.

First clone the default View "Taxonomy term". Then add a page displays which use the default term URL followed by whatever the sub page needs to be eg taxonomy/term/%/ContentTypeA. On this page I can filter by the content type.

Now the page will work at this URL: /taxonomy/term/1/ContentTypeA

However it wont work with the Pathauto path that ive previously set for the term page. EG this wont work: /something/termA/ContentTypeA

To make Pathauto recognize the URL you just need to install the Sub Pathauto module: https://www.drupal.org/project/subpathauto
