Question

我正在尝试更新sprint的变量方面，以用所选sprint的任务填充表格。

这是用于选择sprint的标签：

@foreach($project->sprints as $s)
    <a href="#" >{{$s->version}}</a>
@endforeach

接下来，任务表：

@php ($sprint = null)
@if($sprint != null)
   <table class="table table-striped">
       <thead>
            <tr>
                ...
            </tr>
       </thead>
       <tbody>
            @foreach($sprints->tasks as $task)
               <tr>
                   ...
               </tr>
            @endforeach
       </tbody>            
   </table>
@else
...

如何将$ s分配给$ sprint？

您必须处理控制器中的选定冲刺。

假设您已定义：

路线

Route::get('/project/{projectId}', [
    'uses' => 'ProjectController@show',
    'as' => 'showProject'
])

控制器

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Project;

class ProjectControllerextends Controller
{
    public function show(int $projectId, Request $request)
    {
        $project = Project::with(['sprints.tasks'])->find($projectId);

        $selectedSprint = $request->query('selectedSprint')

        if (!empty($selectedSprint)) {
            $selectedSprint = $project->sprints->first(function($sprint) use ($selectedSprint) {
                return $sprint->id === (int) $selectedSprint;
            });
        }

        return view('projects.show', ['project' => $project, 'selectedSprint' => $selectedSprint]);
    }
}

查看

@foreach($project->sprints as $s)
    <a href="{{route('showProject', ['projectId' => $project->id, 'selectedSprint' => $s->id])}}">
        {{$s->version}}
    </a>
@endforeach

@if($selectedSprint != null)
   <table class="table table-striped">
       <thead>
            <tr>
                ...
            </tr>
       </thead>
       <tbody>
            @foreach($selectedSprint->tasks as $task)
               <tr>
                   ...
               </tr>
            @endforeach
       </tbody>            
   </table>
@else
