Laravel PHP: Uploading Image with Large file size results in 'getClientOriginalName()' being 'null' -

i'm using laravel php , have photo gallery allows user upload images album. when upload images normal file size , less 8mb, uploaded , saved photo album fine. however, when try upload images bigger 8mb, keep getting 'call member function getclientoriginalname() on null' error.

to account large images being uploaded photo gallery, edited 'nginx.conf' , 'php.ini' respectively previous line in 'nginx.conf'

client_max_body_size 8m;  

was changed

client_max_body_size 25m;   

and in 'php.ini', line:

upload_max_filesize = 8m 

was changed to:

upload_max_filesize = 25m 

after making changes in both these files, in putty ran:

sudo service nginx restart sudo service php5-fpm restart 

here controller uploading new photos:

public function store() {     $input = \input::all();      $validation = new validators\stone_photo;          $filename = str_random(4) . \input::file('photo_path')->getclientoriginalname();         $destination = "uploads/photos/";         $upload = \input::file('photo_path')->move($destination, $filename);          if( $upload == false )         {             return \redirect::to('home.index')             ->withinput()             ->witherrors($validation->errors)             ->with('message', 'could not upload picture');         }          $this->stone_photo->create($input, $filename);         return \redirect::route('show_stone', array('id' => $input['stone_id'])); }   

so once again, photos under 8mb still uploaded fine when try upload photo 9mb or over, keep getting error 'call member function getclientoriginalname() on null' error , don't know why. appreciated.

since controller action store i'm guessing have restfull controller , action http method post. if that's case need make sure set set post_max_size in php.ini:

post_max_size = 25m 

otherwise upload_max_filesize overriden post request value of post_max_size (which default 8mb).
