Input class not found in laravel 5 - php

Question

I want to save file uploaded through form into a json file for this I need to get post data which is easily get through Request or Input class methods.
The problem is whenever I use Request or Input I can't get methods such as getClientOriginalName to get name of file and other parameters of file.
My FileController code is as below:
<?php namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request; // this handles both for Input and Request as in laravel 5.1 documentation
use Illuminate\Support\Facades\Input; // though added some classes to get work
use Illuminate\Support\Facades\File; // though added some classes to get work
use Illuminate\Filesystem\Filesystem; // though added some classes to get work
class FileController extends Controller
{
public function index()
{
$files = $this->getAllData();
return view('document.index', compact('files'));
}
public function create()
{
return view('document.create');
}
public function store(Request $request)
{
$name = $request->input('title');
echo $name;
$file = $request->file('afile');
if($request->hasFile('afile')) {
$file = $request->file('afile');
print_r($file); // return array of uploaded as expected
$filename = $file->getClientOriginalName(); // not working
// or
$filename = Input::file('afile')->getClientOriginalName(); // not working
echo $filename;
}
// print_r($file);
// $data= array('title'=>$name, 'afile'=>$file);
// $this->create_entry($data);
// return redirect('document');
}
}
FYI my file upload is sucessful and has got file array as
Array ( [0] => Symfony\Component\HttpFoundation\File\UploadedFile Object ( [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => new_file_1.txt [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => text/plain [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0 [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0 [pathName:SplFileInfo:private] => E:\xampp\tmp\php5680.tmp [fileName:SplFileInfo:private] => php5680.tmp ) )
The only problem is I can't get methods of Symphon2 API though i used
use Input;
or
use Illuminate\Support\Facades\Input;
Every methods of Input are not working either to check its valid or not.
Every tutorial I refer or documentation from laravel 5 uses same as I have used in my code.
So any Kind of suggestion or solution is really appreciated.
the functions as used in this documentation are working but no other methods except than that.

Answer 1

Your missing the use statement for the Input facade. Add the following to your use statements.
use Illuminate\Support\Facades\Input;

Answer 2

You may try this:
$filename = $file->getClientOriginalName();
Since you have already used the following:
$file = $request->file('afile');
The file method returns an instance of Symfony\Component\HttpFoundation\File\UploadedFile and in this case, the instance is already cached in the $file variable.
Also to make sure the upload was successful you may check it using something like this:
if($request->hasFile('afile')) {
$file = $request->file('afile');
$filename = $file->getClientOriginalName() .'.'. $file->getExtension();
}

Answer 3

this works for me
\Input::file('file')->getClientOriginalName();

Answer 4

In your form open tag add 'files' => true
{!! Form::open(array('files' => true, ....)) !!}
In the controller check first if the file has been uploaded correctly
if (!Input::file('afile')->isValid())
{
// return error 50x
}
$filename = Input::file('afile')->getClientOriginalName();
can't apply method to non-object means that Input::file(...) returned null and therefore the file wasn't uploaded or it doesn't exists. Then, when you call ->getClientOriginalName() from a null value php throws an exception.
