Question

我使用分页显示数据库中的所有帖子，下面的代码

public function index() {
    $posts = Posts::where ( 'active', '1' )->orderBy ( 'created_at', 'desc' )->paginate ( 5 );
    $title = 'Latest Posts';
    return view ( 'home' )->withPosts ( $posts )->withTitle ( $title );
}

工作正常。

但是，我希望仅显示与某个类别相关的帖子，而不是所有帖子，以下代码

public function cat() {
    $uri = $_SERVER ['REQUEST_URI'];
    $title = 'Category Posts';

    $uri = str_replace ( "/", "", "$uri" );

    $posts = Posts::where ( 'category', $uri )->orderBy ( 'created_at', 'desc' )->paginate ( 5 );
    /* echo $posts->count(); */
    return view ( 'home' )->withPosts ( $posts )->withTitle ( $title );
}

这里它不起作用，它只显示第一页的5个结果，接下来的页面没有显示任何内容。

我也回应了计数，如果该类别中共有15个帖子，它在第一页显示15个，但在下一页显示0

home.blade.php：

    @extends('app') 

    @section('title') 
    {{$title}}
    @endsection

    @section('leftContent') 
    LeftSide content

    @endsection

    @section('content')
     @if (!$posts->count() ) There is no post till now. Login and write a new post now!!! 
     @else
    <div class="">
        @foreach( $posts as $post )
        <div class="list-group">

我认为解决问题的唯一方法就是玩

自定义Paginator URI

http://laravel.com/docs/5.1/pagination#basic-usage

也试试这个

public function cat($cat) {
    $title = 'Category Posts';
    $posts = Posts::where('category', $cat)->orderBy('created_at', 'desc')->paginate(5);
    return view ('home')->withPosts($posts)->withTitle($title);
}
