How do i download image from database (Codeigniter 4)

Question

I am trying to download my uploaded files(image) by id from the database(phpmyadmin). but there's an error said that variable $id is undefined. this is the code i'm using, i got this code from some tutorial website.

public function download()
    {
        $berkas = new BerkasModel();
        $data = $berkas->find($id);
        return $this->response->download('uploads/berkas/' . $data->berkas, null);
    }

how can i fix this so i can download the uploaded files?

You need to pass the variable $id to the function.

Specific implementation depends on your setup. Looking at the small code fragment you posted (and the absence of any request variable extraction), pass it as function parameter:

public function download($id).

Furthermore you need to adapt your routes.phpand the calling <a> to reflect this change:

routes.php:

$routes->get('download/(:segment)', [CLASSNAME::class, 'download']);

<a href>:

<a href="YOUR_URL/download/<?= esc($id) ?>">Download</a>
