如何使用 laravel 在数据库表中提交多个条目？

Question

我是 laravel 的初学者，我想将多条记录添加到数据库表中，我在下面有一个返回的请求，但我不知道如何将数据提交到表中如何在控制器中创建逻辑有人知道如何要做到这一点，请帮助我，谢谢。 数据库表

    projectissue table  

     Id  | task  | date| project_id

控制器

         public function issuesUpdate(Request $request,Project $project)
         {


              return redirect()->route('project');
         }

return $request

               {
  "_token": "S6typbw0hywPqaUdxCTqWeJNieyl3VieQhCHqDZ7",
    project_id=42;
  "date": [
    "2020-07-06",
    "2020-07-22",
    "2020-07-11"
  ],
  "issue": [
    "dsfsdfsdfsdf",
    "dsfsdfsdfsdf",
    "dsfsdfsdfsdf"
  ]
}

路线

  Route::post('/projects/{project}/issues/update', "ProjectController@issuesUpdate")- 
  >name('project.issues.update');

HTML 视图

     <form action="{{ route('project.issues.update',[$project->id])}}" method="POST">

Answer 1

$dates = request('date');
$issues = request('issue');

for($i = 0; $i < count($issues); $i++)
{

    $issue = new ProjectIssue();
    $issue->task = $issues[$i];
    $issue->date = $dates[$i];
    $issue->project_id = //however you're getting your project id to the controller;
    if($issue->save()){
       continue;
    } else {
      //process error the way you want
    }


}

所以我的代码正在做的是将请求数组存储在一个变量中，并循环遍历表单提交的问题数量。对于存在的每个问题，它都会在表中创建一个新条目，然后继续下一个。我在命名事物的方式上做了一些假设，但这应该足以让你开始。

Answer 2

我建议先阅读文档：https://laravel.com/docs/7.x/eloquent。文档写得很好。不要忘记使用表单请求验证数据（如果你问我推荐的方式）：https://laravel.com/docs/7.x/validation#form-request-validation

我会给你一个先机：

class YourFormRequest
{
    public function rules()
    {
        return [
            'date'    => ['required', 'array'],
            'date.*'  => ['required', 'date'],
            'issue'   => ['required', 'date'],
            'issue.*' => ['required', 'string'],
        ];
    }
}

class SomeController
{
    public function issuesUpdate(YourFormRequest $request)
    {
        foreach ($request->post('date') as $i => $value) {
            ProjectIssue::insert([
                'attribute' => $request->post(),
            ]);
        }

        return redirect()->route('project');
    }
}
