New Plugin: Barcode Generator (FREE)

Showcase
42

Hi @gnelson :

Since the release of the new free plan and it’s limits, the demo plugin only works currently for workflow purposes/editor view, but not in preview mode. Since it’s a free plugin, feel free to take a look at my workflows and test in your own app of choice.

I’d prefer to keep everything free, and to upgrade the demo app to a paid plan would require me to make the plugins not free to offset the costs.

Hi, i’ve been using the QR Generator a while which is great, we love it. Id like to ask for advice around how to or if its possible to track scans. Thank you

@zoeforster87 you’d need to do some build-out to achieve this and essentially set up your own redirect service within Bubble.

Basically, the URL that the user scans should redirect to a blank webpage; on page load, you can do some workflow to track the scan. Then, once the scan is logged, you can redirect the user to the proper link.

Example Setup:

  • Create a Database “Thing” called “QR code Redirect”
  • “QR code Redirect” type needs some fields:
    • scans
    • redirect-url
  • Create a page (such as “/link”) with the type set to “QR code Redirect” (this means all the URLs you encode into your QR code would look like “/link/123…x456…”, basically, the page name followed by unique ID of the type/thing)
  • On page load, you get the QR code Redirect thing, increase the count of scans by 1, then redirect the user to the thing’s redirect-url

Couldn’t you have the link for the QR code have a parameter in it that on page load if the parameter is not empty then log the session?

For instance QR code URL could be:

my page.com?QR_tracking=yes

Then an on page load workflow that says get data from Page URL - QR_tracking is yes then run workflow to increase QR code scan count in database

Hi Nicholas awesome plugin, super easy to use! :clap:

I’m using the client-side Render a QR Code Using a QR Code With Logo.
When button is clicked, the render happens in the element on the page.

Here’s my issue:

  • 1 QR code element
  • different pages the user is going to (1-page-app, so the “THING” is stored in a variable group)
  • variable group is changed, click on button, create the QR code.
    → works the first time.
    → second time, doesn’t work and keeps showing the first time’s QR code. As the qr code was already generated. I tried “reset group” but it won’t reset the QR code element. The only thing that works right now is forcing page refresh so the client-side element is back to being empty.

Am I missing something?

Thanks a lot for your help
Vince

@Vincent_London do you have a workflow I can look at? If you can recreate a minimal example in a demo app I can take a look. I’ve not had anyone report this issue before; so long as you call the “render a qr code” action whenever a change occurs, a new render should occur.

Hi guys, this plugin wont work at all for me. The second I hit the first step of the workflow i get this error:

Thanks,

@nick.lockley I just responded to your email (the error was missing in the email, but now I see it here).

The error is being throw by “Colour QR Code Generator” (Colour QR Code Generator Plugin | Bubble, which is not my plugin). My plugin is: Barcode & QR Code Generator Plugin | Bubble.

Hey @nicholasrbarrow, great plugin, used with EAN13 format and works well. Althogh having trouble with the UPC format which should be 12 characters. Tested all other character lengths as well and doesn’t work, still returns “X is not a valid UPC format”. What seems to be the issue here? Thanks!

EDIT: Found the issue, UPC option currently accepts 11 characters & we have to calculate the last checkdigit ourself

Hey @nicholasrbarrow is it possible to have a higher definition .png out using the svg to png converter function on the next update? Great plugin, looking forward for your response

Hey @nicholasrbarrow,

Hope you’re well!

I’ve been using this plugin for a couple of years now successfully (you can see our chat in thread above!)

Today I’m having issues with an error being thrown and the QR code will not generate. I’ve dropped you an email with the full details and more screenshots on versions and workflow but I’m sharing here for awareness etc and in case my email has gone to spam. Error below.

Am I correct in thinking that there is no way to run the QR code with a logo in the backend to avoid what looks like a CORS issue? (the demo page / editor no longer seems to work)

Thanks in advance,
