Add support for ?view=grid query param to allow shared links to default to grid view

[chuckdries]

inspired by https://help.nextcloud.com/t/question-display-grid-view-when-sharing-a-folder-of-photos-via-url/56812/8

fixes #17762

• I'm open to using a hash instead of a query param as the help forum post suggests. Query param just felt like it made more sense to me.
• Does not implement any UI for setting this query param
• Does not add any documentation that this query param exists
• Subject to the same bug as the forum post: the user must double click the list view button to switch from grid to list view

I'm open to attempting to improve on any of the bullet points above if requested

Generally seems good but I can’t judge the code. :)
Relevant code to pick this up will then have to be implemented in

• the Photos app
• in Files, we could automatically invoke this in a share link when the sender has the folder view set to grid?

I'm not a nextcloud developer but this doesn't seem like a clean implementation. This is useful as a quick and dirty hack in the meantime for people needing the feature, but breaks too many things to be part of the official code.

Currently grid view is set to false in apps/files_sharing/lib/Controller/ShareController.php. Changing it to true works as expected: grid view is shown as initial view for all shared folders.

An UI setting should be added when creating share link for initial view, and the controller should use it to set initial value of 'showgridview'.

Of course this is all my humble opinion.

I'm no php developer but I'll take a shot at that this weekend

I'm sorry, to ask here but I'm still figuring things out...
I'm looking for this specific feature (presenting grid-view for public shared links)

Do I read this history correctly, that it was merged to Nextcloud 24 RC 1?
I tried installing the latest/edge version from Snap wich seems to be based on 25 and adding "?view=grid" didn't work ... so I guess its not included?
On the other hand I found no way to install 24RC1 via snap as it seems it's not a implemented channel?

Any help would be appreciated 🙈

This PR was not merged. Sorry, but I didn't get around to making the requested changes and no longer have time or desire to do so.
