Laravel 图片上传到数据库

Question

这个函数是我用来存储新公司的函数：

public function store(Request $request)
{   

    $file = $request->file('logo');
    $filename = 'company-logo-' . time() . '.' . $file->getClientOriginalExtension();
    $path = $file->storeAs('public', $filename);
    dd($path);            

    Company::create([
        'name' => $request->name,
        'email' => $request->email,
        'logo' => $request->logo,
        'website' => $request->website
    ]);

    return redirect('/company/all');
}

此视图的格式为：

@extends('layouts.app')

@section('content')
    <div class="card">
        <div class="card-body">
            <h4 class="card-title">Create a Company</h4>
        </div>

        <div class="container">
            <div class="jumbotron">
                <ul class="list-group">
                    <li class="list-group-item">
                        <h3>Enter Company Information:</h3>
                        <form action="{{ route('company.store') }}" enctype="mutlipart/form-data" method="POST">
                            @csrf
                            <div class="form-group">
                                <input type="text" class="form-control" name="name" placeholder="Company name" value="{{ old('name') }}">
                            </div>
                            <div class="form-group">
                                <input type="text" class="form-control" name="email" placeholder="Email" value="{{ old('email') }}">
                            </div>
                            <div class="form-group">
                                <input class="form-control" type="file" name="logo">
                            </div>
                            <div class="form-group">
                                <input class="form-control" type="url" name="website" placeholder="Website" value="{{ old('website') }}">
                            </div>
                            <button class="btn btn-primary" type="submit">Add Company</button>
                        </form>
                    </li>
                </ul>
            </div>
        </div>
    </div>
@endsection

这是路线：

路线::post('/add', 'CompaniesController@store')->名称('store');

好吧，当我尝试提交此表单时发生的事情是 $file 变量总是返回 null:

Error
Call to a member function getClientOriginalExtension() on null
http://localhost:8000/company/add

基本上我想做的是将图像名称发送到数据库并将图像上传到我的 public 文件夹。这段代码都不会发生。当我删除从 $file 到 dd($path) 的部分时；它将值添加到数据库，但图像尚未上传。

有什么帮助吗？提前致谢。

尝试更改为：

public function store(Request $request)
{   

    $file = $request->file('logo');
    $path = '';
    if($file) {
        $filename = 'company-logo-' . time() . '.' . $file->getClientOriginalExtension();
        $path = $file->storeAs('public', $filename);
    }            

    Company::create([
        'name' => $request->name,
        'email' => $request->email,
        'logo' => $path,
        'website' => $request->website
    ]);

    return redirect('/company/all');
}

Answer 2

  if (Input::hasFile('logo')) {
                $file = Input::file('logo');
                $ext = $file->getClientOriginalExtension();
                $file_name = 'company-logo-' . time() . ".{$ext}";
                $path = base_path().'/public/';
                $file->move($path , $file_name);
            }

Answer 3

首先表格上的属性是错误的enctype="mutlipart/form-data"，应该是enctype="multipart/form-data"

或者您可以根据需要使用以下代码的替代方法：

if($request->hasFile('logo')){
        $file = $request->file('logo');
        $fileName = 'company-logo-' .time().$file->getClientOriginalName();
        Storage::put('public/'.$fileName,file_get_contents($file));
        now you can store the $filename variable in database and image will be uploaded to storage/app/public folder
    }

请在文件顶部添加 use Storage 和运行 php artisan storage:link 以在存储文件夹和 public 文件夹

之间创建符号 link

Answer 4

首先，您在表单中更改 enctype="multipart/form-data" 而不是 enctype="mutlipart/form-data"。 然后将此代码放入您的控制器

public function store(Request $request)
{
  if($request->hasFile('logo')) {
    $img_ext = $request->file('logo')->getClientOriginalExtension();
    $filename = 'company-logo-' . time() . '.' . $img_ext;
    $path = $request->file('logo')->move(public_path(), $filename);//image save public folder
  }
  //You should store only filename not path in db
  Company::create([
    'name' => $request->name,
    'email' => $request->email,
    'logo' => $filename, 
    'website' => $request->website
  ]);

    return redirect('/company/all');
}

您可以使用文件池。核心库是用 vanilla JavaScript 编写的，因此可以在任何地方使用。 访问： https://pqina.nl/filepond/
