Invalid argument supplied for foreach()

Could you show us an error? Apache logs?

 (1/1) ErrorException

Invalid argument supplied for foreach()

'files' => null that'll be the problem. What does you view template look like?

@extends('layouts.ad')

@section('content')
       

@if ($message = Session::get('success'))
<div class="row">
    
    <div class="col-md-12">
        

            <div class="alert alert-success">

                <p>{{ $message }}</p>

            </div>
     </div>
    
</div>

@endif

        <div class="col-sm-10 well-lg">
            <div class="row">    
                <div class="container-fluid">
                    <div class="form-group">
                      <h2>Simple Multiple Upload</h2>
                      {!! Form::open(array('url'=>'/admin/upload','method'=>'POST', 'files'=>true)) !!}
                      {!! Form::file('images[]', array('multiple'=>true, 'id' => 'file')) !!}
                        <p>{!!$errors->first('file')!!}</p>
                        @if(Session::has('error'))
                          <p>{!! Session::get('error') !!}</p>
                        @endif
                      {!! Form::submit('Submit', array('class'=>'btn btn-lg btn-primary col-md-4')) !!}
                      {!! Form::close() !!}
                    </div>
                </div>

try to create a own request and validate from there

@LaraStorm If i create validation try to upload correct .jpeg image it shows me still "file required not saving to the database"

 public function upload(Request $request){
       
       $this->validate($request,[
         'file' => 'required|mimes:jpeg,png,jpg,gif,svg|max:2048'
        ]);

        $files = Input::file('images');
        
        $file_count = count($files);
        
        $uploadcount = 0;
        
        foreach ($files as $file) {   
            
            
                $destinationPath = 'images';
                $filename =  $file->getClientOriginalName();
                $file->move($destinationPath,$filename);
                $uploadcount ++;
               
                $file->getClientOriginalExtension();
                $entry = new \App\image();
                $entry->mime = $file->getClientMimeType();
                $entry->filename = $filename;
                $entry->save();
                
            }
            
        
    return redirect('/admin/image')->with("success","Uploaded Sucessfully");    

   } 

you just wanna upload multiple images to the database ?

@LaraStorm I am trying to upload multiple images but still the validation show "The file field required"

Your validation is failing because you are checking a file input name rather than images.

On the face of it, your form and controller code looks okay. Can you check the request in the browser's dev tools to see that the form data contains the images?

@tykus forms data does not contains images it stores only images file name for example demo.jpeg!!

Are you doing anything (javascript-related) to modify the FormData before the form submits, or is it plain old HTML?

@tykus

How to check with images can you explain??

@tykus Simple blade file

{!! Form::open(array('url'=>'/admin/upload','method'=>'POST', 'files'=>true)) !!}
                      {!! Form::file('images[]', array('multiple'=>true, 'id' => 'filename')) !!}
                        <p>{!!$errors->first('file')!!}</p>
                        @if(Session::has('error'))
                          <p>{!! Session::get('error') !!}</p>
                        @endif
                      {!! Form::submit('Submit', array('class'=>'btn btn-lg btn-primary col-md-4')) !!}
                      {!! Form::close() !!}

@tykus

I have checked with displaying the data inside the foreach loop also it is working

In the controller; so, the images are being submitted?

@tykus image filenames are getting submitted it is working the problem is in validation.Suddenly the user clicks on the submit button i am trying show validation to user saying image field required or jpeg image format etc.. that i cannot achieve it.something missing in foreach??

Hi Please check this example http://www.expertphp.in/article/laravel-53-upload-image-with-validation-example.

the example is just for uploading one image.

and for multiple files validation please check this answer : https://stackoverflow.com/questions/38326282/validating-multiple-files-in-array

Right, so the validation is the problem, you need to allow for an array being received:

$this->validate($request, [
    'images.*' => 'required|mimes:jpeg,png,jpg,gif,svg|max:2048'
]);

@tykus but still lies same problem

ErrorException thrown with message "Invalid argument supplied for foreach()"
