Free QR code generator API

[rcacciato]

I have a database where I am creating QR codes with URLs for our customers to place orders. I've been using a free service called qrserver.com and have been using this script around this (I can't recall where I found the script):

Set Variable [ $theURL; Value:"https://api.qrserver.com/v1/create-qr-code/?size=150x150&data="&qrgen::orderurl ]
#Make sure the field you are inserting into is on the layout that the script is running from.
#----MODIFY FIELDS----
Insert from URL [ qrgen::QR Code; $theURL ] [ Select; No dialog ]
#Turn this on for troubleshooting. If something is wrong, you will see some error information coming back from Google.
// Open URL [ $theURL ] [ No dialog ]

Unfortunately when I ran the script today it hung on the URL Data Transfer script saying "Transferring" (see screenshot). 

When I went to the qrserver.com website nothing came up, so they must have shut this down for whatever reason.

Does anybody else have any ideas how to generate QR codes for free? This is an important part of our system.

Thanks in advance.

There are many APIs providing QR codes to choose from.

Alternatively you could implement some Javascript code in a web viewer - though that could be a bit tricky if you're still on version 16.

Thanks. I found this: https://sourceforge.net/projects/phpqrcode/

I've installed it on our server and it works great. My script is as follows, where server.com is my server (sorry it's not the real url since I don't want anybody generating orders!) and qrgen::orderurl is the url which loads the order page:

Set Variable [ $theURL; Value:"https://server.com/phpqrcode/index.php?data="&qrgen::orderurl ]

#Make sure the field you are inserting into is on the layout that the script is running from.

#----MODIFY FIELDS----

Insert from URL [ qrgen::QR Code; $theURL ] [ Select ]

#Turn this on for troubleshooting. If something is wrong, you will see some error information coming back from Google.

// Open URL [ $theURL ] [ No dialog ]

If I copy the value of $theURL and paste it into a browser, the correct QR code is generated. But when I run the script it pastes the Textmate icon (I use Textmate as my text editor) and not the QR code into the field like the screenshot. It's odd because with the api.qrserver.com url the QR code was pasted perfectly. I've tried turning "automatically encode URL" off but that doesn't work, same error. Any idea what I may be doing wrong here? I'm totally baffled since this worked before.

Thanks.

ps: here's a url if you would like to try it:

The URL you are using does not insert an image file into the target container. It inserts a plain-text file with a .php extension, containing:

<h1>PHP QR Code</h1><hr/><img src="temp/test1df79d71d92e5295995c5f63318b56d2.png" /><hr/><form action="index.php" method="post">

                <tr style="border-top:2px solid black"><th style="text-align:right">TOTAL: </th><td>0.010714s</td></tr>
            </tfoot>
            </table>

You need a URL that links to the image file itself.
