如果一个项目中有多项费用，我如何将它们加在一起并成为一行？

Question

I have two table as you can see that relations each other.

I want to see this table

如何在我的 blade 文件或控制器中执行此操作。

这是我的 blade 文件；

@foreach ($costs as $cost)
                    @foreach ($projects as $project)
                    @if($project->id == $cost->project_id)


                  <tr class="odd">
                    <td>{{ $project->id }}</td>
                    <td>{{ $cost->price }}</td>

                  </tr>

                  @endif
                  @endforeach
                  @endforeach



public function tablo1()
    {
        $costs =  DB::table('cost_manages')
            ->whereExists(function ($query) {
                $query->select(DB::raw(1))
                    ->from('projects')
                    ->whereColumn('projects.id', 'cost_manages.project_id')->groupBy('project_id');
            })
            ->get();

        $projects =  DB::table('projects')
            ->whereExists(function ($query) {
                $query->select(DB::raw(1))
                    ->from('cost_manages')
                    ->whereColumn('cost_manages.project_id', 'projects.id');
            })
            ->get();

        

        return view('home.muhasebe_Tablo1', [
            'costs' => $costs,
            'projects' => $projects
        ]);
    }

那个是我的控制器。项目编号 11 有 2 个成本。我想通过收集它们来写一个记录。请帮助我

使用连接：

DB::table('projects')
->leftjoin('cost_manages', 'projects.id','const_manages.project_id')
->select('projects.id as id', 'projects.name as name', 'cost_manages.cost as cost')->get()

然后遍历这个。

If there are multiple expenses in a project, how can I sum them together and make a single row?

php

laravel

laravel-blade
