Laravel 5.1 分页问题

Question

我正在使用分页来显示我在数据库中的所有帖子，代码如下

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，我只想显示与某些类别相关的帖子，而不是所有帖子，代码如下

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 );
}

这里不起作用，它只显示第 1 页的 5 个结果，接下来的页面没有显示任何内容。

我也附和了计数，如果该类别中总共有 15 个帖子，则第一页显示 15，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">
            <div class="list-group-item s">
                <h3>

                    @if(!Auth::guest() && ($post->author_id == Auth::user()->id ||
                    Auth::user()->is_admin())) @if($post->active == '1')

我相信解决你问题的唯一方法就是玩

自定义分页器 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);
}
