来自AJAX请求的分页不能正常工作-Laravel 5.6

Question

我正在使用Laravel 5.6--Jquery Ajax

url : '{{action('PostController@searchAdmin')}}'

我将该操作的返回作为带有数据的部分

return view('back.partials.searchResult', ['posts' => $posts, 'trashed' => $trashed]);

我将主标记的内容替换为部分标记

除了当结果计数大于10（分页的断点）时，其他一切都正常工作。

Undefined variable: posts

我使用$posts->links()来显示控件

Answer 1

我找到了一个解决办法所以我把它贴出来

在web.php中

Route::get('/search', function(Request $request) {
    $search = $request->search;
    $trashed = Post::trash()->count();
    $posts = Post::notTrash()
        ->where('title', 'like', '%' . $search . "%")
        ->orWhere('post_type' , 'like', '%' . $search . '%')
        ->paginate(10);


    $posts->withPath('?search=' . $search);
    return view('back.partials.searchResult', ['posts' => $posts, 'trashed' => $trashed, 'search' => $search]);
});

 这段代码用于测试目的，不久将导出到一个名为SearchController的新控制器中

public function index(Request $request)
{

    // GET parameters
    $paginate = $request->input('paginate') ?? 10;
    $search = $request->input('search') ?? null;

    if($search !== null) {
        $posts = $this->checkCategories($paginate, $search);
    } else {
        $posts = Post::notTrash()->orderBy('id', 'ASC')->paginate($paginate);
    }
    $trashed = Post::trash()->count();
    $posts->withPath('?search=' . $search);

    return view('back.index', ['posts' => $posts, 'trashed' => $trashed, 'search' => $search]);
}

private function checkCategories($paginate, $search)
{
    $categories = Category::all();
    foreach ($categories as $category) {

        if(strpos(strtolower($category->name), $search) === false) {
// @TODO: Change for stripos 
            $posts = Post::notTrash()
                ->where('title', 'like', '%' . $search . '%')
                ->orWhere('post_type', 'like', '%' . $search . '%')
                ->paginate($paginate);
        } else {
            return Category::find($category->id)->posts()->paginate($paginate);
        }
    }

    return $posts;

}

   @if($search !== null)
        {{ $posts->appends($search)->links() }}
    @else
        {{ $posts->links() }}
    @endif

现在替换

{{ $posts->links() }}

解决方案是$var->**WithPath()**和处理GET参数
