Is there a complete example?

[zerocarbthirty]

I'm trying to use this library along with chillerlan\QRCode to implement 2fa.

I've been able to generate the uri and show the QR code but i'm a bit confused about what you're supposed to do from there.

Is there a complete example which includes capturing and validating the code from the user anywhere?

The docs appear to sort of skip over a little bit of the work that is required for this to be a complete solution.

If that is intentional it's okay I am just confused.

Hey, have you checked the examples over here? https://github.com/chillerlan/php-authenticator/tree/main/examples

Yes, sorry it looks like the totp example is the entire PHP flow in one continuous segment of code. I thought that there would need to be multiple segments.

Like creating a secret then creating the QR code/presenting the QR code, validating the QR code, writing the secret to permanent storage and then validating the codes using the secret on an ongoing basis. I guess I was just confused. I'll keep messing with it though. Thanks for the hard work.

I ran into one problem with your QRCode lib.

``echo'<img src="'.(new QRCode)->render($data).'" alt="QR Code" />';

is the example given. I need to pass the QRCode to a template to display it to the user so I tried this:

$qr = new QRCode->render($data);

to store it in a passable variable and I get an error about unexpected ->

Like I said eirher way I will just keep trying until it works.

thanks.

Yea, the flow is straightforward enough so i kept it in a single file - needless to say that creation of the secret and verification of a user's OTP code are separate flows.

This bit of code is only valid as of PHP 8.4, which allows omitting the braces around a new instance creation (similar to Javascript).

$qr = new QRCode->render($data);
$qr = new QRCode($qrOptions)->render($data);

// PHP < 8.4 
$qr = (new QRCode)->render($data);
$qr = (new QRCode($qrOptions))->render($data);

But you probably want to instance the QRCode earlier anyway:

$qrcode = new QRCode($qrOptions);

// ...

$image = $qrcode->render($data);

okay, sorry for asking. Thanks.
