QR code URL does not consider subfolder installation

[jacques42]

Describe the bug

Generating the QR code, the URL assumes that Photobooth always is installed in the /var/html/www folder (document root of the webserver). Installing in a subfolder (i.e. /var/html/www/photobooth) QR code URLs won't work

To Reproduce
Steps to reproduce the behavior:

1. Install in a subfolder
2. Go to dev mode, take a picture
3. Generate QR code
4. Try URL from QR code

Expected behavior

The URL encoded in the QR code needs to reflect the actual path of Photobooth installation root. File api/qrcode.php

photobooth/api/qrcode.php

Line 12 in cb07a00

$url = 'http://' . $SERVER_IP . '/api/download.php?image=';

Environment (please complete the following information):

• OS: iOS, Raspberry Pi
• Browser : All

Photobooth

• Did it work before? no
• Which version of Photobooth are you using? v3 Beta

Additional context

[andi34]

$config['webserver']['ip'] = '127.0.0.1/Photobooth';

Or via Webinterface.

Or does it conflict with the remotebuzzer?

Could you try:

<?php
require_once '../lib/config.php';

if (!isset($config['webserver']['ip'])) {
    $SERVER_IP = $_SERVER['HTTP_HOST'];
} else {
    $SERVER_IP = $config['webserver']['ip'];
}

$filename = $_GET['filename'];
$api_path = getrootpath('../api');
include '../vendor/phpqrcode/qrlib.php';
$url = 'http://' . $SERVER_IP . $api_path . '/download.php?image=';
QRcode::png($url . $filename, false, QR_ECLEVEL_H, 10);
