Use the Accept-Language header when assigning a default language to a new user session

[jonasraoni]

Describe the problem you would like to solve
When a user accesses an OJS (OMP, OPS) website, OJS creates a session and assigns the primary locale to it. This becomes the default language the user will work with while interacting with the website, until he changes it. However, this may not correspond to the user's preferred language.

Describe the solution you'd like
Instead of using the primary locale, we should use the Accept-Language header to detect the user's current locale and automatically select that (if available).

@jonasraoni the link isn't taking me directly to the comment. This happens sometimes as GitHub hides some comments. Can you copy/paste the discussion or reasoning into this issue?

You can access it by clicking "Show Resolved" links until you find the right one (:man_facepalming:) but to save you the trouble it's this conversation:

Ah, so this is during installation. I've updated the issue title/description, thanks!

[asmecher]

@NateWr, no, this isn't for during installation -- it's for when a user without a session first hits the OJS website.

[NateWr]

Ok, then I'm not understanding the issue description. Can one of you (@jonasraoni, @asmecher) update this with a clearer description of the problem and solution?

[asmecher]

@jonasraoni and @NateWr, I've updated the description. @jonasraoni, did I capture what you were proposing?

[NateWr]

Got it, thanks!

@asmecher Some older PRs which I've rebased recently, so they are still ok to be merged.

@jonasraoni I don't think anyone has identified this as a priority so I haven't reviewed it; strategically, I would much rather we considered e.g. adopting Laravel's session management toolset rather than refining our own.
