how to fix Call to a member function getClientOriginalExtension() on null in laravel 5.6
in my laravel application I am using dropzone programmatically to upload images. this is my Controller to store images in VehicleController
public function store(Request $request)
{
$photos = $request->file('file');
if (!is_array($photos)) {
$photos = [$photos];
}
if (!is_dir($this->photos_path)) {
mkdir($this->photos_path, 0777);
}
for ($i = 0; $i < count($photos); $i++) {
$photo = $photos[$i];
$name = sha1(date('YmdHis') . str_random(30));
$save_name = $name . '.' . $photo->getClientOriginalExtension();//this is line 75
$resize_name = $name . str_random(2) . '.' . $photo->getClientOriginalExtension();
Image::make($photo)
->resize(250, null, function ($constraints) {
$constraints->aspectRatio();
})
->save($this->photos_path . '/' . $resize_name);
$photo->move($this->photos_path, $save_name);
$upload = new Upload();
$upload->filename = $save_name;
$upload->resized_name = $resize_name;
$upload->original_name = basename($photo->getClientOriginalName());
$upload->save();
}
return Response::json([
'message' => 'Image saved Successfully'
], 200);

Dropzone.autoDiscover = false;
// Dropzone class:
var myDropzone = new Dropzone("div#my-dropzone", { url: '/form'});
routes
Route::post('form','VehicleController@store');
but when my form submit button clicked following errors occurred,
1/1) FatalErrorException

i don's see your blade file code, but I think you have to check this option for multiple image upload: http://www.dropzonejs.com/#config-uploadMultiple

how to fix my null images in
$photos = $request->file('file');

Well there is different misbehaviour in the way you try to handling it.
From what I understand, dropzone and your view' form are different entities.
Right now I would say that when you add images to dropzone, it is dynamically trying to send your images one by one through an ajax request to your route. If you want to pursue this way you need to append the csrf token to this ajax request. But having it within a form lead to a misconception to me, cause let say you have 10 images to upload, you are going to submit the form (with the select fields) before that all the images are being sent to your server one by one .
So If I were you I would try to follow the link sent before explaining how to combine a normal form and dropzone, which is basicaly explaining that the images are going to be sent only after the submit button' click in your request. You could then treat the files send as an array. (request->file[])
