Hi jesu,
You can generate a QR Code with a dynamic value. To ensure each QR Code is unique, I recommend using the server action GenerateGUID. This way, the value of the QR Code will be a combination of the GUID and your variable, ensuring that every QR Code generated is different.
didnt know about this? but generateguid is new to me how is this a validation how is it workd? but thanks!
I've updated the .oml file and added a new screen called RandomQRCode. This screen includes a data action that uses the GenerateGUID server action (you'll need to add this dependency from the (System) module). To do that, just click the plug icon at the top and select the module you need.
To generate the QR codes, I'm appending the output from GenerateGUID with a value + "&" + {CountVariableValue}. This is just a placeholder, you can use any value you'd like!
I’m using the "&" symbol simply to make these values easier to identify within the string. The GenerateGUID part ensures that each QR code is unique.
