Call to a member function getClientOriginalName() on array laravel
提问by blastme
I'm trying to post an image from a one to many relationship while also doing the CRUD (create part), but I am having some trouble doing it. I keep on getting this error,Call to a member function getClientOriginalName() on array, whenever I try to use associate to define the relationship together with user_info with user_image table. So what should I do?
我正在尝试从一对多关系发布图像，同时还进行 CRUD（创建部分），但是我在做时遇到了一些麻烦。,Call to a member function getClientOriginalName() on array每当我尝试使用关联来定义与 user_info 和 user_image 表的关系时，我都会不断收到此错误。所以我该怎么做？
Here are my codes: createController:
这是我的代码：createController：
public function create1(){
return view('create1');
}
public function store1(Request $request){
$this->validate($request, [
'input_img' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
$user_info = Session::get('data');
$UserImage = new UserImage($request->input()) ;
if($file = $request->hasFile('input_img')) {
$file = array();
$fileName = $file->getClientOriginalName() ;
$destinationPath = public_path().'/images' ;
$file->move($destinationPath,$fileName);
$UserImage->userImage = $fileName ;
$UserImage = UserImage::create(['file' => $request->file('input_img')]);
$UserImage->user_infos()->associate($user_info);
}
$UserImage->save() ;
return redirect('/home');
}
HomeController(this is where I print out my information)
HomeController（这是我打印信息的地方）
public function getInfo($id) {
$data = personal_info::where('id',$id)->get();
$data3=UserImage::where('user_id',$id)->get();
return view('test',compact('data','data3'));
blade.php (how I show the image in view)
Blade.php（我如何在视图中显示图像）
@foreach ($data3 as $object9)
<img width="100" height="100" src="{!! $object9->signature !!}">
@endforeach
UserImage model(in table I used binary format to store in DB)
UserImage 模型（在表中我使用二进制格式存储在 DB 中）
class UserImage extends Eloquent
{
protected $fillable = array('userImage','user_id');
public function user_infos() {
return $this->belongsTo('App\user_info', 'user_id', 'id');
}
class user_info extends Eloquent
{
protected $fillable = array('Email', 'Name');
protected $table = user_infos';
protected $primaryKey = 'id';
public function UserImages() {
return $this->hasOne('App\UserImage','user_id');
}
}
create1.blade.php(this is how I upload the image)
create1.blade.php（这是我上传图片的方式）
<form class="form-horizontal" method="post" action="{{ url('/userUpload')}}" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label for="imageInput" class="control-label col-sm-3">Upload Image</label>
<div class="col-sm-9">
<input data-preview="#preview" name="input_img" type="file" id="imageInput">
<img class="col-sm-6" id="preview" src="" ></img>
</div>
</div>
<div class="form-group">
<div class="col-md-6-offset-2">
<input type="submit" class="btn btn-primary" value="Save">
</div>
</div>
</form>

I think you have a problem inside store1()method. You sould not re-declare $file.
我认为您在store1()方法内部有问题。你不能重新申报 $file。
if($file = $request->hasFile('input_img')) {
$file = array();
$fileName = $file->getClientOriginalName();
Instead get the file using the file()method:
而是使用以下file()方法获取文件：
if($request->hasFile('input_img')) {
$file = $request->file('input_img');
$fileName = $file->getClientOriginalName();
See more on the Laravel's requests documentation.
在Laravel 的请求文档中查看更多信息。

Read through your logic in the store1method again... You are setting the $filevariable to an empty array and then trying to call the getClientOriginalName()method on it:
store1再次通读方法中的逻辑......您将$file变量设置为一个空数组，然后尝试getClientOriginalName()在其上调用该方法：
$file = array();
$fileName = $file->getClientOriginalName();
