It looks like you are calling ->appendson your variable called $booksin several places within your view.
看起来您正在调用->appends在$books视图中的多个位置调用的变量。
If $booksis empty (i.e. null) this might be causing your problems.
如果$books为空（即null），这可能会导致您的问题。
I would suggest wrapping your $booksin if is set functions as a starting point
我建议将您$books的 if is set 功能包装为起点
if (isset($books) && $books != NULL) {
$books->appends(['query' => Input::get('query')])->render()
} else {
// Do something which tells the user that there are no books
}
An even better solution would be to handle all of the logic for the view in your controller and use something like a @forelseloop instead of a @foreachloop. This would make it easier to handle situations where you return an empty collection.
更好的解决方案是处理控制器中视图的所有逻辑，并使用@forelse循环而不是@foreach循环之类的东西。这样可以更轻松地处理返回空集合的情况。
@forelse ($books as $book)
// Do your for each book markup
@empty
// Do markup which shows when you have no books
@endforelse
