QR Code Generator

I was wondering if there is a laravel library to generate QR Codes?

Not laravel specific, but this is the most popular (by huge margin) composer package for QR generation with php: https://packagist.org/packages/bacon/bacon-qr-code

The package @ohffs linked to is more popular, but also does a lot more. If you're only interested in QR it might be overkill -- it also looks like it's only for PDFs, which probably won't help if you just need to place the QR code somewhere and have no use for PDF generation. :)

A lot of that generates PDFs with the content in it. I am looking for something that generates the image QR code.

@qljsystems Yeah, the maintainer either closed or moved the repo with that QR package since that link was posted over year ago. Not sure what brunowerneck can do about that.

I don't know if you want a complex QR code with background images, or alternative colors ... but as long as all you want is a simple black on white QR Code ... and you don't need it to be larger than 547pixels by 547 pixels ... then you can do it all with one simple call to the Google API.

The old Google Chart Api was depreciated ... but the Infographics Api is still available

To create a QR Code with the text "QR Code for Laracasts" in a size of 500 pixels by 500 pixels you just need the folloing URI

https://chart.googleapis.com/chart?chs=500x500&cht=qr&chl=QR%20Code%20for%20Laracasts

You can view the documentation at

https://developers.google.com/chart/infographics/docs/overview

use this package : simplesoftwareio/simple-qrcode and save image :

$fileNameCodeUnique = md5(time()); $qrcode = QrCode::size(512) ->format('svg') ->generate($request->code, base_path() . '/storage/app/public/qrproducts/qrcodes/' . $fileNameCodeUnique . '.svg');
