即使上传文件，Laravel Input :: hasFile（'image'）也会返回false [英] Laravel Input::hasFile('image') returns false even if a File is uploaded

问题描述

我有一个图片上传的表单字段，我用'files'=> true打开，就像这样：

  {{Form :: label（'image'，'Image'）}} 
 {{Form :: file（'image'）}} 
  

在我的控制器中，我想检查一个文件是否已经上传，并用它来做：

  if（Input :: hasFile（'image'））{
 $ in_path ='img /'; 
 $ in_extension = Input :: file（'image'） - > getClientOriginalExtension（）; 
 $ filename = Input :: get（'name'）。。。$ in_extension; 
 Input :: file（'image'） - > move（$ in_path，$ filename）; 
 $ user-> image = $ filename; 
} 
  

但Input :: hasFile总是返回false，我不知道为什么。


有没有人有想法？




编辑！：

 输入::文件（ '图像'）; 
  

结果为：

  Symfony \ Component \HttpFoundation\File\UploadedFile Object 
（
 [test：Symfony \ Component \HttpFoundation\File\UploadedFile：private =>> ; 
 [originalName：Symfony \ Component \HttpFoundation\File\UploadedFile：private] => test.JPG 
 [mimeType：Symfony \Component\HttpFoundation\File\UploadedFile ：private] => application / octet-stream 
 [size：Symfony \ Component \HttpFoundation\File\UploadedFile：private] => 0 
 [error：Symfony \Component\\ \\ HttpFoundation \ File \UploadedFile：private] => 1 
 [pathName：SplFileInfo：private] => 
 [fileName：SplFileInfo：private] => 
）
  

我已经测试过另外一个用户的图片，这个工作正常。我不明白这是为什么这是为一些用户和其他一些不工作。


有可能是某种不被接受的图片吗？$ / $>

解决方案

我解决了什么问题。
代码是好的，但问题是一些图片只是大。




编辑：


不要惊慌指出，编辑 upload_max_filesize 可以解决问题。

I have a Form field for an Image upload, which I open with 'files' => true, like so:

{{ Form::label('image', 'Image') }}
{{ Form::file('image') }}

And in my Controller I want to check if a File was uploaded and do something with it:

if (Input::hasFile('image')){
        $in_path = 'img/';
        $in_extension = Input::file('image')->getClientOriginalExtension();
        $filename = Input::get('name').".".$in_extension;
        Input::file('image')->move($in_path, $filename);
        $user->image = $filename;
    }

But Input::hasFile always returns false and I don't know why.
Does anyone have an idea?

EDIT!:

Input::file('image');

results in:

Symfony\Component\HttpFoundation\File\UploadedFile Object
(
[test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 
[originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => test.JPG
[mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => application/octet-stream
[size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
[error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 1
[pathName:SplFileInfo:private] => 
[fileName:SplFileInfo:private] => 
)

I have tested around with another picture for another User and this works fine. I don't get why this is working for some Users and for some others not.
Is there maybe some kind of Pictures that are not accepted?

解决方案

I solved what was wrong. The code is fine, but the problem was some pictures were simply to big.

EDIT:
As Don't Panic pointed out, editing upload_max_filesize can solve the problem.
