How set value from one field to another on Save

[vallter2]

How to copy value from one field to another on save? I have input value (without value from query) and need set to another variable on Save...

public function createOrUpdate(Events $event, Request $request)
    {
        $event->fill($request->get('event'))->save();
        Alert::info('You have successfully created an post.');
    }

$event->other = 'other'

You can find out how models work in the framework documentation.

Thank you... For request variable update I use this:

$request->merge([
            'video' => [
                'image' => $newValue,
            ]
        ]);
