blade | Use Blade templates without the full Laravel framework

So I am having problems storing my picture of the user in the specified directory. The image is already in the database but when I call the data it does not show anything. How do I store it in the public folder and the database here is my lines of code:

RegisterController.php

I am having difficulty with multi-select boxes with Laravel, particularly, reading values from the database and displaying these values so they can be edited in my edit view.

In my controller, in the store function, I am using the implode function to save positive integers into a database field.

I'm building a web app using Laravel 8 and one thing I tend to struggle with is the complex relationships and accessing the data. I've started reading on hasManyThrough relationships but I'm not convinced that's the correct way to do it for my scenario.

The app is used by travelling salesmen to check in to a location when they arrive safely.

I have three main tables:

• Locations (where they are visiting),
• Checkins (where their check in data is stored, e.g. time),
• Users

This is where it gets a little complex and where I find myself not being able to see the wood for the trees...

• Locations have many users, users have many locations. Many-to-many pivot table created.
• Locations have many check ins, check ins have many locations. Many-to-many pivot table created.
• Check ins have many users, users have many check ins. Many-to-many pivot table created.

As such they're all created using a belongsToMany relationship.

Now what I'd like to do is access the user of the check in so I can call something similar to on my show.blade.php:

My code doesn't work. I use Laravel framework. Error on the picture. I think maybe it's looping
