Question

好吧，也许这是一个菜鸟问题，但是当我尝试从表单存储数据时，我在查询中使用了$ request-> input来获取需要的插入字段，但是查询不会运行。注意：如果我只设置了$ project_id = 6，就可以运行。

 public function store(Request $request)
    {
         $project_id = $request->input('project_id');

         $company = Project::where('id', $project_id)->first();

         if(Auth::check()){
            $task = Task::create([
                'name' => $request->input('name'),
                'project_id' => $project_id,
                'company_id' => $company->id,
                'days' => $request->input('days'),
                'hours' => $request->input('hours'),
                'user_id' => Auth::user()->id
            ]);
            if($task){
                return redirect()->route('tasks.index')
                ->with('success' , 'Task created successfully');
            }
        }

            return back()->withInput()->with('errors', 'Error creating new task');
    }

注意：

我尝试了一些我在网上发现的不同事情，例如$ project_id = $ request-> project_id或$ project_id = $ request ['project_id']

request-> input是否仅用于插入并且不能用作普通变量？

更新：这是它来自的create.blade表格

让我们在下面检查您的Task.Delay：

<form>

在此代码中，您有一个名为<input class="form-control" type="hidden" name="project_id" value="{{ $project_id }}"/> @if($projects != null) <div class="form-group"> <label for="company-content">Select Project</label> <select name="project_id" class="form-control"> @foreach($projects as $project) <option value="{{ $project_id }}">{{ $project->name }}</option> @endforeach </select> </div> @endif的隐藏输入，并且如果"project_id"不是$projects，则还有一个null名为{{ 1}}。多个具有相同名称的元素是无效的，并且可能导致问题。

第二，在这一行：

select

"project_id"与上面<option value="{{ $project_id }}">{{ $project->name }}</option>输入中的值相同。当您遍历$project_id时，应为hidden：

$projects

最后，如果要发送$project->id，请确保它是有效值，并考虑调整逻辑以仅在<option value="{{ $project->id }}">{{ $project->name }}</option>为{{ 1}}：

$project_id

所有这些调整后，您应该可以使用hidden

检索期望值。
