Laravel 5 图片上传错误的数据库路径

Question

我的图片上传输入出现问题。我正在尝试在我的 Laravel 5 项目中创建文件上传输入，但我遇到了保存到数据库图像表中的路径问题。

表单正在工作并且正在发布，但是，当数据库保存它正在输入的图像的路径时：/Applications/MAMP/tmp/php/phptvwTYW 而不是只获取文件名。

此外，该文件正在移动到正确的public/img 文件夹。

代码

public function store(PostRequest $request)
{
    $this->createPost($request);

    $destinationpath = public_path() . '/img/';

    $filename = $request->file('image_url')->getClientOriginalName();

    $request->file('image_url')->move( $destinationpath,$filename );

    flash()->success('Your Post Has Been Created!');

    return redirect('posts');
}

Answer 1

因为你在移动之前保存，

//before moving 
$request->file('image_url')->getPath(); // returns Applications/MAMP/tmp/php/php...

要获得新移动文件的完整路径，您可以这样做

//After moving
$res = $request->file('image_url')->move( $destinationpath,$filename );
$my_new_path = $res->getPath(); // returns [public_path]/img/filename.jpg

您可以在移动文件后通过更新帖子来保存它，或者在保存时使用事件移动它 看这里http://laravel.com/docs/master/eloquent#events

这是我的项目中当前使用的示例控制器函数

public function postCreateInternal(CreateDocumentInternalRequest $request) {
        $data_information = $request->only(['title', 'assigned_to', 'folder_id', 'document_source']);
        if ($request->hasFile('file_name') && $request->file('file_name')->isValid()) {
            $document = $request->file('file_name');
            #creating file Name
            $mytime = Carbon::now();
            $date_now = $mytime->toDateTimeString();
            $date_now = $this->prepareFileNameString($date_now);
            $document_extension = $document->getClientOriginalExtension();

            $document_name = $this->prepareFileNameString(basename($document->getClientOriginalName(), '.' . $document_extension));
            $document_fullName = $document_name . "_" . ($date_now) . "." . $document_extension;
            $data_information['file_type'] = $document->getMimeType();
            $data_information['file_size'] = $document->getSize();
            $data_information['file_name'] = $document_fullName;
            $data_information['file_download_type'] = "Internal";
            $document->move(public_path() . '/uploads/documents/', $document_fullName);
        }
        if ($pot = $this->document->create($data_information)) {
            $this->notification_admin->sendCreateDocument($data_information);
            return redirect()->route('documents')->with('success', trans('document.create.msg_success'));
//          return redirect()->route('update/document', $pot->id)->with('success', trans('document.create.msg_success'));
        }
        return redirect()->route('create/document')->with('error', trans('document.msg_error'));
    }

CreateDocumentInternalRequest 根据 Laravel 5 基本上用于文件和其他数据验证

而查看文件似乎是这样的：

{!! Form::open(["class"=>"form-horizontal","data-parsley-validate"=>"data-parsley-validate",'role'=>'form','files'=>true]) !!}
<div class="form-group  required {{ $errors->first('file_name', ' has-error') }}">
    {!!Form::label('file_name', trans('document.label.file_name'), array('class' => 'col-md-4 control-label left-label'))!!}
    <div class="col-sm-6">
        {!! Form::file('file_name') !!}
        {!! $errors->first('file_name', '<span class="help-block">:message</span>') !!}
    </div>
</div>
{!! Form::close() !!}

在我当前的实现中，首先我检查上传的文件，用当前时间戳重命名文件名，然后重新上传我想要的位置。 如果您需要任何帮助，请告诉我以更好的方式改进我提供的方法。

试试这个：

public function store(PostRequest $request, Post $post) { 
    $destinationpath = public_path() . '/img/';

    $filename = $request->file('image_url')->getClientOriginalName();

    $request->file('image_url')->move( $destinationpath,$filename );

    $post->create([
        'field1' => $val1,
        'imageField' => $filename,
        'field2' => $val2
        ]);

    flash()->success('Your Post Has Been Created!');

    return redirect('posts');
}

Answer 4

我找到了我的问题的解决方案。 我必须对控制器中的 store 和 createPost 函数进行一些更改才能使其正常工作。

对于我拥有的控制器：

公共功能存储（PostRequest $request） { $destinationpath = public_path() 。 '/img/'; $filename = $request->file('image_url')->getClientOriginalName(); $request->file('image_url')->move($destinationpath,$filename); $this->createPost($request, $filename); flash()->success('您的帖子已创建！'); 返回重定向（“帖子”）； } 私有函数 createPost(PostRequest $request, $new_url) { $post = Auth::user()->posts()->create($request->all()); $post->image_url = $new_url; $post->保存（）； $this->syncTags($post, $request->input('tag_list')); 返回 $post; }

我希望这对可能遇到同样问题的其他人有所帮助。 谢谢大家的帮助！

这是非常简单的方法：

public function store(PostRequest $request)
{
    $image_name = $request->file('image')->getClientOriginalName();
    $request->file('image')->move(base_path().'/public/images', $image_name);
    $post = ($request->except(['image']));
    $post['image'] = $image_name;
    Post::create($post);
    Session::flash('success_message', 'Post has been added successfully!');
    return redirect('teacher');
}
