Multiple files upload Laravel 5.8 - laravel

Question

I want to upload multiple files in Laravel but it's not working I tried in my controller
Edit: I means page refresh but no error or registred data in the db
I followed https://www.youtube.com/watch?v=wk5usyevYj0
public function storescan(Request $request){
$this->validate($request,[
'file' => 'required|file|mimes:gif,jpg,png,jpge,jpeg|max:102048'
]);
$files=$request->file('file');
foreach($files as $file){
Document::create([
'doc'=>$file->getClientOriginalName(),
'path'=>$file->store('public/storage'),
'support'=>$request->input('support'),
'ecole'=>$request->input('ecole'),
'jour'=>$request->input('jour'),
'cycle'=>$request->input('cycle'),
'type'=>'Image',
'niveau'=>$request->input('niveau'),
'matiere'=>$request->input('matiere'),
'user_id'=>Auth::user()->id
]);
}
return redirect()->route('prof.document.create')->withMessage('✅ Image(s) ajoutée(s) avec succès!');
}
And here is my route and formular
Route::post('/professeur/myDoccy/scan/create','DocumentController#storescan')->name('prof.document.createscan');
Formular everything is correct I minimized the code and left only the input file
<form enctype="multipart/form-data" class="form" action="{{ route('prof.document.createscan') }}" method="POST">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
{{ csrf_field() }}
<label class="purple" >Charger l’image </label><br/>
<input required type="file" multiple name="file[]" accept='image/*' class="form-control-file border-or m-1" >
</div>
</form>

Answer 1

You should check $errors variable (read more https://laravel.com/docs/5.8/validation).
You have problem with validation. You have rule
'file' => 'required|file|mimes:gif,jpg,png,jpge,jpeg|max:102048'
But it will work for single file. You have multiple of them, so it should be:
'file.*' => 'required|file|mimes:gif,jpg,png,jpge,jpeg|max:102048'
Also, you can use "image" rule instead of file with all mimes.

Answer 2

I solved the issue by deleting the validate part
And adding to all fillable attributes in my model but still no validation possibility
class Document extends Model
{
use SoftDeletes;
public function user(){
return $this->belongsTo('App\User');
}
protected $fillable = [
'doc','support','ecole',
'path',
'jour',
'cycle',
'type',
'niveau',
'matiere',
'user_id'
];
}
function
public function storescan(Request $request){
$files=$request->file('file');
foreach($files as $file){
Document::create([
'doc'=>$file->getClientOriginalName(),
'path'=>$file->store('public/storage'),
'support'=>$request->input('support'),
'ecole'=>$request->input('ecole'),
'jour'=>$request->input('jour'),
'cycle'=>$request->input('cycle'),
'type'=>'Image',
'niveau'=>$request->input('niveau'),
'matiere'=>$request->input('matiere'),
'user_id'=>Auth::user()->id
]);
}
return redirect()->route('prof.document.create')->withMessage('✅ Image(s) ajoutée(s) avec succès!');
}
