Laravel: Undefined value on image upload - php

Question

First Laravel Project. I building a feature where I can upload an image. Everything what I did is based on this PDF (page 98-101)
My blade.php
<?php echo Form::open(array('url' =>'/product/imgedit','files'=>'true'));
echo 'Adj meg egy új képet';
echo Form::file('image');
echo Form::submit('Upload File');
echo Form::close();?>
My router
Route::get('product/{id}/imgedit', 'InventoryController#imgreq');
Route::post('product/imgedit', 'InventoryController#imgupl');
My Controller:
public function imgreq($id)
{
$product = DB::select('select * FROM inventory WHERE barcode = ?', [$id]);;
return view('productimgupl', ['product' => $product]);
}
public function imgupl()
{
$file = $request->file('image');
//Display File Name
echo 'File Name: ' . $file->getClientOriginalName();
echo '<br>';
//Display File Extension
echo 'File Extension: ' . $file->getClientOriginalExtension();
echo '<br>';
//Display File Real Path
echo 'File Real Path: ' . $file->getRealPath();
echo '<br>';
//Display File Size
echo 'File Size: ' . $file->getSize();
echo '<br>';
//Display File Mime Type
echo 'File Mime Type: ' . $file->getMimeType();
//Move Uploaded File
$destinationPath = '/media/productimg/';
$file->move($destinationPath, $file->getClientOriginalName());
}
Error message:
ErrorException in InventoryController.php line 28: Undefined variable:
request
What I did wrong?

Answer 1

You need to bring in the Request object in your method's argument. Like so:
public function imgupl(Request $request) {
// code...
}
Then you may use $request in the method.
By default Laravel includes this class when you use php artisan make:controller by inserting it at the top of your Controller with this line: use Illuminate\Http\Request;. All you are doing is casting the Request object to a variable named $request for use in that method.
Hope this helps!
