Storing image to Public folder Laravel 5.1 - php

Question

I'm trying to save an image to a folder in my laravel application.
I'm getting the error:
fopen(F:\blog\public/usr-data/photos): failed to open stream: Permission denied
Here's my laravel controller which is writing to this folder.
$error = false;
$absolutedir = public_path();
$dir = '/usr-data/photos';
$serverdir = $absolutedir.$dir;
$filename = array();
foreach($_FILES as $name => $value) {
$json = json_decode($_POST[$name.'_values']);
$tmp = explode(',',$json->data);
$imgdata = base64_decode($tmp[1]);
$fileAry = explode('.',$json->name);
$extension = strtolower(end( $fileAry ));
$fname = $card->id.'.'.$extension;
$handle = fopen($serverdir,'w');
fwrite($handle, $imgdata);
fclose($handle);
$filename[] = $fname;
}
I've tried using
Icacls "F:\blog\public/usr-data/photos" /grant Everyone:(OI)(CI)F
But no joy - still the same issue.

Answer 1

You need to set up writing permissions on a storage and public folders and then all folders inside these ones. Use right click on a folder, go to Properties and change folder permissions.

EDIT: This will work for Linux only. I'm keeping this answer in case anyone runs into the same problem on a Linux machine.
Try this:
php artisan cache:clear
sudo chmod -R 777 app/storage
composer dump-autoload

Instead of using file write, you can also use the Laravel filesystem storage class. Please try with the below given example.
$image represents the encoded image.
$Id represents the id of the user.
public function imageUpload($image, $Id)
{
//Decode base64 string to image
$profile_image = 'image/jpeg;base64,' . $image;
$new_data = explode(";", $image);
$data = explode(",", $new_data[1]);
$file = base64_decode($data[1]);
$imageFileName = $Id . '.jpeg';
$image_path = '/storage/' . $imageFileName;
Storage::put($imageFileName, $file);
return $image_path;
}
