Laravel: Save Base64 .png file to public folder from controller

Question

I send a png image file to controller in base64 via Ajax. I\'ve already test and sure that controller has received id but still can\'t save it to public folder.

Answer 1

My solution is:

public function postTest() {
        $data = Input::all();

        //get the base-64 from data
        $base64_str = substr($data->base64_image, strpos($data->base64_image, ",")+1);

        //decode base64 string
        $image = base64_decode($base64_str);
        Storage::disk('local')->put('imgage.png', $image);
        $storagePath = Storage::disk('local')->getDriver()->getAdapter()->getPathPrefix();
        echo $storagePath.'imgage.png'; 
        $response = array(
            'status' => 'success',
        );
        return Response::json( $response  );
}

Answer 2

$file = base64_decode($request['image']);
        $folderName = 'public/uploads/';
        $safeName = str_random(10).'.'.'png';
        $destinationPath = public_path() . $folderName;
        $success = file_put_contents(public_path().'/uploads/'.$safeName, $file);
        print $success;

Answer 3

This is an easy mistake.

You are using public_path incorrectly. It should be:

$path = public_path() . "/img/designs/" . $png_url;

Also, I would avoid your method of sending the image. Look at a proper upload in a form and use Laravel's Input::file method.

Answer 4

what am i doing is using basic way

$file = base64_decode($request['profile_pic']);
            $folderName = '/uploads/users/';
            $safeName = str_random(10).'.'.'png';
            $destinationPath = public_path() . $folderName;
            file_put_contents(public_path().'/uploads/users/'.$safeName, $file);

           //save new file path into db
            $userObj->profile_pic = $safeName;
        }

Answer 5

I'v done it!!

I replaced $data->base64_image to $_POST['base64_image'] and then use $result = file_put_contents($path, $image); instead of Image::make($image->getRealPath())->save($path);

But this doesn't look like a laravel ways. I you have another way that look more elegant please tell me!

Answer 6

Actually, Input::all() returns an array of inputs so you have following:

$data = Input::all();

Now your $data is an array not an object so you are trying to access the image as an object like:

$data->base64_image

So, it's not working. You should try using:

$image = $data['base64_image'];

Since it's (base64_image) accessible from $_POST then Input::file('base64_image') won't work because Input::file('base64_image') checks the $_FILES array and it's not there in your case.
