Joomla Tag Menu Item Routing Broken

[MaxLynam]

Steps to reproduce the issue

Create Tags.
Add some of those tags to different articles.
Create menu items which match the single tags you have created.
Test clicking on the tags when viewing the articles.
Note the articles that display when you arrive at the tag menu list.
They do not match (on most occasions) with the tag you clicked on or assigned to that menu item.

Expected result

When you click on a tag in an article, it should go to the menu item and display all atricles that match the tag set for that menu item.

Actual result

Have created tag menu items to try and get decent SEF urls, but it does not display the articles with the set (single) tag for that menu item ... it only displays the articles from the tag that was created first (in ID order)

Additional comments

.... tried with sh404sef installed to see if it would fix it, but didn't change behaviour - still wrong - had to manually re-write the URLs to get it to work

---

Notes from my dev:
I've found the issue. Its not a sj404sef issue. Somehow a [0] is appearing in joomla tag url which is making in-built router confused. When I follow url without it [0], it works fine.

For example,

http://www.domain.com.au/index.php?option=com_tags&view=tag&id[0]=2&Itemid=245

and

http://www.domain.com.au/index.php?option=com_tags&view=tag&id=2&Itemid=245

Well, I've fixed it by rewriting urls. I believe there's a bug in joomla- tag has a menu and sef url enabled, it cant route properly. May be they havent tried this feature. Hope it would be fixed in next joomla release.

I'm sure it probably has something to do with https://github.com/joomla/joomla-cms/blob/staging/components/com_tags/router.php however can't work out how to submit a new issue in the Joomla github repo.

I know where the &id[0] is coming from. It's because JTags allows in the single item view multiple ids. You can in fact pass an array of ids (&id[0]=12&id[1]=23) or a string with comaseparated ids (&id=12,23).
Please note that I don't say this is good behavior, just stating why you see the URL as it is.

well ... the menu type we used is for a single tag ... so this menu type can't display multiple IDs and does not return the correct ID when clicked on from the articles tag - so routing would indeed appear broken and returns the incorrect results.

The multiple tag menu item should be able to return multiple tag listings - that is correct behaviour.

Whether single tag or multi-tag, having it operate in a way that actually returns the incorrect (tag) result is not the desired behaviour.
That's why we had to add our own redirects to get it to work.

At ALL times ..... when [0] is removed from the URL routing works as expected and the correct information is displayed.

If you used the "Tagged Items" menu item, then this is in fact not a "single tag" menu item. You can use it with a single tag, but you can add as many tags as you want. com_tags doesn't have a "single tag" view. There is only a "list of tags" and a "list of tagged items".

I'm not saying there is no bug. I'm actually fully expect there to be a lot of bugs. I just wanted to explain why there is such a strange id. Because this is important if someone wants to fix it.

At ALL times ..... when [0] is removed from the URL routing works as expected and the correct information is displayed.

It will work for a single tag, but it likely breaks as soon as multiple tags are assigned to the menuitem.

Please see if #5105 fixes some of your problems.
