hello ,,, I searched too much about any way to add barcode to output of gravity form filling ,,, but not found ,, and finally after experiments I found way to do that easily ,, then how to do that ??

1- you need to install QR Code Generator plugin in wordpress .

2- put this code in pdf file that you selected with form ( html design allowed ) : [qrcode content=”{entry_url}” size=”120″ alt=”ALT_TEXT” class=”CLASS_NAME”]

3- about item will show you information in database but if you want to show pdf file when scan barcode you can put this code in confirmation or notification or pdf as you want : (({entry_id}/ )) ,,, folder id like : 579f43414b084 and you can copy it from pdf link .

that is all ,,, Im using it without problem
