我想查看我的页面，但它一直说未定义的变量：$jobs [重复]

Question

我希望用户在单击按钮时查看另一个页面。在新页面中，已经从数据库中获取了一些信息。但是，我声明了所有内容，但它仍然说未定义的变量。

form.blade.php

@foreach ($jobs as $job)
    <form action="{{route('job-apply', $job->$id)}}" method="post" enctype="multipart/form-data">
        {{ csrf_field() }}
        <div class="form-group form-group-material a-form-group">
            <label class="label">Full name</label>
            <input type="text" class="form-control" name="fullname" required />
        </div>
        <div class="form-group form-group-material a-form-group">
            <label class="label">Email</label>
            <input type="email" class="form-control" name="email" required />
        </div>
        <div class="form-group form-group-material a-form-group">
            <label class="label">Phone Number</label>
            <input type="tel" class="form-control" name="contact" required />
        </div>
        <div class="form-group form-group-material a-form-group">
            <label class="label">Address</label>
            <textarea class="form-control" name="address" cols="30" rows="3"></textarea>
        </div>
        <div class="form-group form-group-material a-form-group">
            <label class="label">Category</label>
            <input type=text class="form-control" name="category" disabled value="{{ $job->category }}" required />
        </div>
        <div class="form-group form-group-material a-form-group">
            <label class="label">Position</label>
            <input type="text" class="form-control" name="position" disabled value="{{ $job->position}}" required />
        </div>
        <div class="form-group control-file a-file">
            <input type="file" name="attachment" accept=".doc,.pdf" multiple />
            <div class="file-path-wrapper">
                <i class="lni lni-paperclip text-primary"></i>
                <input class="file-path form-control" placeholder="Add Attachment(.doc;.pdf)" />
            </div>
        </div>         
        <button class="btn btn-success" type="submit">Send</button>
    </form>
@endforeach

我的form.blade 中有一个错误

表单控制器

$jobs = Job::get();
$jobs=Job::where('id',$id)->first();
return view('candidate.apply');

有人可以帮助我，因为我是 Laravel 的新手吗？这是我的主页，用户单击按钮并将其重定向到表单

<div class="col-md-2">
    <div class="slide-btn">
        <a href="{{ route('job-apply',$job->id) }}" class="btn btn-success">Apply</a>
    </div>
</div

作业控制器

public function index()
{
    $jobs = Job::get();
    $company = Company::get();
    $menu = Menu::get();
    $current_menu = 4;
    // $jobs = Job::latest()->paginate(5);
    $jobs = Job::
        join('company', 'company.id', '=', 'jobs.company')
        ->get();
        
    return view('jobs.joblist', compact('jobs', 'company', 'menu', 'current_menu'));

}

public function create()
{
    return view('jobs.create');
}


public function store(Request $request)
{
    $request->validate([
    
        'company' => 'required',

    ]);


    Job::create($request->all());

    return redirect()->route('jobs.index');

    $jobupdate->save();

    // Job::update($request->all());

    return redirect()->route('jobs.index');
}


public function destroy(Job $job)
{
    $job->delete();

    return redirect()->route('jobs.index');
}

public function active(Request $request)
{
    // dd('text');
    $job = Job::where('company',$request->jobId)->first();
    $activeVal=request()->get('value');
    // dd($activeVal);
    if($activeVal == 1)
    {
        $activeVal=1;
    }else{
        $activeVal=0;
    }
    $job->status=$activeVal;
    $job->save();

    $output['success'] = 'success';

    return response()->json($output, 200);

}

Answer 1

您需要使用view的第二个参数将数据传递给视图。

$jobs = Job::get();

return view('candidate.apply', ['jobs' => $jobs]);

Answer 2

在你的 return 语句中添加 laravel 中的 compact 函数。

$jobs = Job::get();
    
    return view('candidate.apply', compact('jobs'));
