[5.3] Fix languagefilter automatic language change redirection when SEF is enabled

[Flowman]

Pull Request for Issue #32816 .

Summary of Changes

The language filter is configured for automatic language change and SEF is enabled.

When a logged-out user attempts to access a menu item that requires specific access permissions (e.g., https://test.com/en/somepagewithaccess), they are correctly redirected to the login page. The return URL is set to the intended destination, so the user should be redirected there after a successful login.

However, after signing in, the user is taken back to the login page instead of the originally requested page.

The PR checks if mode_sef is enabled and does the correct redirect.

Testing Instructions

1. Create a site with 2 languages and SEF enabled.
2. Create a menu item with access registered.
3. Enabled automatic language change in Language Filter plugin.
4. Try to access the restricted menu URL.
5. Login to the site.

Check the screen capture in the original issue for more info.

User get redirected to the login page when the language filter is configured for automatic language change and SEF is enabled.

Expected result AFTER applying this Pull Request

I can't get this PR to display default behaviour so have given up on testing it!

@Flowman I, too, like @ceford have no issues with the BEFORE condition (which for me actually is the AFTER condition) on a Joomla 5.3.2 test site and a 5.3.2 live site - both work as you explain that it should if the PR was applied without the need for the patch.

Is it possible that since 2021, the Joomla Core has fixed this?

Either that or there is a missing step in the Testing Instructions (which do appear pretty clear, easy, thorough), I even tried things beyond your description like setting the Article to a specific language but it still worked fine without the patch.

Looking forward to your reply/thoughts.

I can confirm the bug. The key to replicating the bug is to make sure that the menu items are associated.

Amended instructions

• Create a site with 2 languages eg french and english and SEF enabled and a language switcher module
• Create a french article and a menu item to that article with access registered.
• Create an english article and a menu item to that article with access registered
• associate the two menu items
• Enabled automatic language change in Language Filter plugin.
• Try to access the restricted menu URL.
• Login to the site.
• Log out of the site and using the language switcher module change to the second language
• Try to access the restricted menu URL.
• Login to the site.

In the second example you are redirected to the english article on login
