Laravel - pagination sorting by created_at - laravel

Question

So guys I add pagination to my project and I'm almost finishing it, witch by the way is my first project ever, and all I need to do right now is to set pagination by created_at.So I need to put posts from the same day on same page link. Right now it shows me posts from different days on one page. And after that I just need to show price sum of that day. If you know please help me, this would be my first project as a student, I'm still learning. Thank you !!
Here is my 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', $posts);
}
}
Here is my home.blade.php
#extends('layouts.theme')
#section('content')
<style>
body{
margin: 0;
background-color: #EBEBEB;
}
</style>
<div class="mainl">
<div class="row">
<div class="columna">
<h1>{{ Auth::user()->name }}</h1>
<hr>
</div>
<div class="columns">
<a href="{{ route('logout') }}" id="logout"
onclick="event.preventDefault();
document.getElementById('logout-form').submit();">
{{ __('LOGOUT') }}
</a>
<form id="logout-form" action="{{ route('logout') }}" method="POST" style="display: none;">
#csrf
</form>
</div>
</div>
</br></br></br>
#if(count($posts)> 0)

And I found something from past questions here in stack overflow and it's working but I have a problem with that, so
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);
}
When I add this ->where('created_at', '>=', \Carbon\Carbon::now()->subDays(10))->get(); it shows me all posts from past 10 days but after that 10 days nothing, could I use this but to sort it by all days, not to set maximum days?
I also add this code to my price sum and it is working but as I said just for past 10 days
<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>
Thank you again and I would really appreciate it if you help me with this. It's my first project and I'm very happy about it.

Answer 1

What your current code is doing is taking all the posts, sort it by created_at and then show 3 at a time. It doesn't care about what day it is or how many $post are there for that particular day.
What I understand that, you want to do is to show it by date. In that case, your query should filter based on date.
What you need to do is pass the date to the controller and fetch only posts from that day. It is a bit tricky. You need to pass today's date to controller.
In HTTP GET method your URL should contain the date. For example, it can be something like http://example.com/index?date=20190716. Notice that "date=20190716" part. You can get this in controller. Then you can get the posts of that day by writing,
$date = new Carbon(request('date'));
$posts = Post::where('user_id', Auth::id())
->whereDate('created_at','=',$date)
->orderBy('created_at', 'DESC')
->paginate(3);
Now, what it will do is get only the posts from 16th July, 2019.
This is the main idea. How you pass the date is entirely on you. You can do that in several ways. You can use JS, HTTP GET method and HTTP POST method.

Answer 2

Try
public function index()
{
$posts = Post::where('user_id', Auth::id())->get();
return view('home')->with('posts', $posts);
}

Answer 3

Try this also, I hope helps you
public function index()
{
$dateFromUrl = \Carbon\Carbon::createFromFormat('d/m/Y', request()->date);
$posts = Post::where('user_id', Auth::id())->where('created_at',$dateFromUrl)->orderBy('created_at', 'DESC')
->get();
$sum = 0;
foreach($posts as $post){
$sum+=$post->price;
}
return view('home', compact("posts","sum"));
}
