Validate in Laravel, That at Least One Checkbox is Checked


If you have a form with multiple checkboxes (categories, tags, ...) and you want to be sure, that at lease on checkbox is checked, you can add this validation:

public function store(Request $request)
	$validatedData = $request->validate([
		'category' => 'required',

	// more code


The ‘required’ validation checks, that there is at least one checked checkbox – all you need.
