how to display uploaded file from writable/uploads in codeigniter 4

In Codeigniter4 how to show the path of uploaded file from the writable/uploads folder?

The file may be an image, doc, pdf or CSV. I upload the file using the below code and store it in DB.

$file->move(WRITEPATH . 'uploads', $fileName);

all uploaded records are listed on a page and have to open the uploaded CSV/excel in a new tab from the listing page.

but I did not get the path from the writable/uploads folder to open in a new tab.

<?=WRITEPATH.'uploads/'.$allList->documentCsv?>

when I copy the link and open it on a tab it downloaded.

Please explain how to show the path.

Thanks

Solution

Based on your clarification. I get this summary.

You want to show file binary value but instead of download you wanna show it in browser.

I have this code for you

public function showFile()
{
    helper("filesystem");
    $path = WRITEPATH . 'uploads/';
    $filename = 'logo-at.png';

    $fullpath = $path . $filename;
    $file = new \CodeIgniter\Files\File($fullpath, true);
    $binary = readfile($fullpath);
    return $this->response
            ->setHeader('Content-Type', $file->getMimeType())
            ->setHeader('Content-disposition', 'inline; filename="' . $file->getBasename() . '"')
            ->setStatusCode(200)
            ->setBody($binary);
}

The supported extension will show the file value in browser. If not, it will downloaded.
