get error while file upload in laravel - php

Question

I am trying to upload image in laravel. But when i upload it gives error.
Call to a member function getClientOriginalExtension() on null
Here is my Blade file form
{{Form::open(array('url' => '/AddNewBlog','id'=>'blogadd' ,
'method' => 'post','class'=>'form-row','files'=>true,
"enctype"=>"multipart/form-data"))}}
And here is controller
$imagename_bg = time() . '.' . $photo->getClientOriginalExtension();
$destinationPath = public_path('/uploads/blog');
$thumb_img = Image::make($photo->getRealPath())->resize(750, 450);
$thumb_img->save($destinationPath . '/' . $imagename_bg, 80);
$photo->move($destinationPath, $imagename_bg);
Please help me how to resolve this problem.

Answer 1

I am not able to understand your code. if you are looking for uploading image and resize using intervention package try this:-
if($request->hasFile('blogimage')){
if (Input::file('blogimage')->isValid()) {
$file = Input::file('image');
$img = Image::make($file);
$img->resize(400,270);
$name = pathinfo($_FILES['image']['name']);
$destination = public_path('/uploads/blog');
$ext = $name['extension'];
$rand= time().str_random(6).date('h-i-s').'.'.$ext;
$img->save($destination.$rand);
}
}
Or Without intervention pacakge:-
if($request->hasFile('blogimage')){
if (Input::file('blogimage')->isValid()) {
$file = Input::file('blogimage');
$destination = public_path('/uploads/blog');
$ext= Input::file('blogimage')->getClientOriginalExtension();
$mainFilename =time().str_random(5).date('h-i-s');
$file->move($destination, $mainFilename.".".$ext);
}
}
Hope it helps!

Answer 2

$photo = $request->file('file_name');

Answer 3

You only need to use this:
$photo = $request->file("blogimage");
instead of:
$photo = $request->input("blogimage")
Hope this will fixed your problem!
