【问题描述】：
所以伙计们，我在我的项目中添加了分页，我快完成了，顺便说一句，女巫是我的第一个项目，我现在需要做的就是通过 created_at 设置分页。所以我需要发布帖子从同一天在同一页面链接。现在它在一页上显示不同日子的帖子。之后我只需要显示当天的价格总和。如果你知道请帮助我，这将是我作为学生的第一个项目，我还在学习。谢谢！！
这是我的 HomeController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\User;
use App\Post;
use DB;
use Auth;
class HomeController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* @return \Illuminate\Contracts\Support\Renderable
*/
public function index()
{
$posts = Post::where('user_id', Auth::id())->orderBy('created_at', 'DESC')
->paginate(3);
return view('home')->with('posts', $posts);
}
}
这是我的 home.blade.php
@extends('layouts.theme')
@section('content')
<style>
body{
margin: 0;
background-color: #EBEBEB;
}
</style>
<div class="mainl">
<div class="row">
<div class="columna">
<h1>{{ Auth::user()->name }}</h1>
<hr>
</div>
<div class="columns">
<a href="{{ route('logout') }}" id="logout"
onclick="event.preventDefault();
document.getElementById('logout-form').submit();">
{{ __('LOGOUT') }}
</a>
<form id="logout-form" action="{{ route('logout') }}" method="POST" style="display: none;">
@csrf
</form>
</div>
</div>
</br></br></br>
@if(count($posts)> 0)

我在堆栈溢出中从过去的问题中找到了一些东西，它正在工作，但我有一个问题，所以
public function index()
{
$posts = Post::where('user_id', Auth::id())->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->get();
return view('home')->with('posts', $posts);
}
当我添加此 ->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->get(); 时，它会显示过去 10 天的所有帖子，但在那 10 天之后什么都没有，我可以使用它，而是按所有天数排序，而不是设置最长天数吗？
我还将此代码添加到我的价格总和中，它正在工作，但正如我所说的过去 10 天
<tfoot>
<tr>
<th>UKUPAN IZNOS: {{ Auth::user()->posts->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->sum('cijena')}}€</th>
<th>KARTICA: {{ Auth::user()->posts->where('placanje', 'Kartica')->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->sum('cijena')}}€</th>
<th>GOTOVINA: {{ Auth::user()->posts->where('placanje', 'Gotovina')->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->sum('cijena')}}€</th>
<th>VIRMAN: {{ Auth::user()->posts->where('placanje', 'Virman')->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->sum('cijena')}}€</th>
</tr>
</tfoot>
再次感谢您，如果您能帮我解决这个问题，我将不胜感激。这是我的第一个项目，我对此感到非常高兴。
