php - Laravel - 将价格与支付方法的 where 方法相加

问题描述

所以现在我正在研究需要对每种付款方式进行价格求和的项目，例如，如果有人用现金支付，则需要对每笔现金支付的总价格求和。这是我的代码

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)
        <table>
            <thead>
                <tr>
                    <th>BR.KESICE</th>
                    <th>IME I PREZIME</th>
                    <th>BR.TELEFONA</th>
                    <th>POSAO</th>
                    <th>CIJENA</th>
                    <th>PLACANJE</th>
                    <th>POPUST</th>
                    <th>DATUM PREUZ.</th>
                    <th>DATUM IZDAV.</th>
                    <th>SMJENA</th>
                    <th>RADNIK</th>
                    <th>STATUS</th>
                    <th>IZMIJENI</th>

                </tr>
            </thead>
            <tbody>
                @foreach($posts as $post)
                <tr>
                    <td>{{$post->br_kesice}}</td>
                    <td>{{$post->ime}}</td>
                    <td>{{$post->br_telefona}}</td>
                    <td>{{$post->posao}}</td>
                    <td>{{$post->cijena}}</td>
                    <td>{{$post->placanje}}</td>
                    <td>{{$post->popust}}</td>
                    <td>{{$post->datum_preuz}}</td>
                    @if($post->status == 1)
                        <td>/</td>
                    @else
                        <td>{{$post->datum_izdav}}</td>
                    @endif
                    <td>{{$post->smjena}}</td>
                    <td>{{$post->radnik}}</td>
                    <td>
                        @if($post->status == 0)
                        <span class="label label-primary" id="statusdeaktivan">Deaktivan</span>
                        @elseif($post->status == 1)
                        <span class="label label-success" id="statusaktivan">Aktivan</span>
                        @elseif($post->status == 2)
                        <span class="label label-danger" id="statusdeaktivan">Rejected</span>
                        @else
                        <span class="label label-info" id="statusdeaktivan">Deaktivan</span>
                        @endif
                    </td>
                    @if($post->status == 3)

                    @else
                    <td><a href="posts/{{$post->id}}/edit" class="edit"><i class="far fa-edit"></i></a></td>
                    @endif

                </tr>

                @endforeach
            </tbody>
            <tfoot>
                <tr>
                    <th>UKUPAN IZNOS:&nbsp;&nbsp;{{ Auth::user()->posts->sum('cijena') }}&euro;</th>
                    <th>KARTICA:&nbsp;&nbsp;{{ Auth::user()->posts->where('placanje', 'Kartica')->where('created_at','=',$date)->sum('cijena')}}&euro;</th>
                </tr>
            </tfoot>
        </table>
        <br><br>
        {{ $posts->links() }}
        @else
            <p>Trenutno nema unosa.</p>
        @endif
    </div>
@endsection

在此home.blade.php我where('created_at','=',$date) 从我的 HomeController 中输入，但它不起作用。在我的主页上，它只显示今天发布的帖子。这就是我在我的 HomeController.php：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use App\Post;
use DB;
use Auth;
use Carbon\Carbon;

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()
    {
        $date = new Carbon(request('date'));

        $posts = Post::where('user_id', Auth::id())
                ->whereDate('created_at','=',$date)
                ->orderBy('created_at', 'DESC')
                ->paginate(30); //add {{ $posts->links() }} if paginate is enabled
        return view('home', compact('date', $date))->with('posts', $posts);
    }
}

所以我所需要的只是当经理创建帖子并输入付款方式例如“Kartica”时，在我的主页中它的表格页脚它需要汇总今天发布的所有帖子的总付款以及“Kartica”付款方式的所有价格也从今天开始. 如果有人有想法请告诉我，谢谢！

解决方案

created_at字段使用YYYY-MM-DD HH:II:SS格式，因此您必须按日期而不是按日期时间过滤。
你可以这样做：

public function index()
{
    $date = new Carbon(request($date))->format("Y-m-d");

    ...
    ->whereRaw('DATE(created_at) = ?', $date)
    ...
}

whereRaw方法可用于将原始 where 子句注入查询。
