Answer 1

您似乎在视图中的多个位置调用名为->appends的变量上的$books。

如果$books为空（即null），则可能会导致您的问题。

如果将设置函数作为起点，我建议将$books包裹起来

if (isset($books) && $books != NULL) {
    $books->appends(['query' => Input::get('query')])->render()
} else {
    // Do something which tells the user that there are no books
}

更好的解决方案是在控制器中处理视图的所有逻辑，并使用@forelse循环而不是@foreach循环。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

对模板的更正

<?php $myArray = array(); ?>

@if  (empty($myArray))
    @foreach($books as $Afica)
    <?php $collection = collect($Afica);?>
    <article class="one-third">
        <figure><a href="#" title=""><img src="{{ $collection->get('photo_url') }}" alt="" style="height: 215px!important;" /></a></figure>
        <div class="details">
            <h3>{{{  $collection->get('name') }}}
                <span class="stars">
                    <?php 

                    for ($i=1 ; $i<= $collection->get('class') ; $i++) {
                          echo ' <i class="material-icons">&#xE838;</i>';
                    }
