Issue with dynamic QR codes for events

User_Z5U0D

Hi all I'm trying to create QR codes for live events so we can scan people in to capture attendance.

I am using this code to insert the QR code unique to a person that wen scanned triggers a blind form submit to capture the attendance.

<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=https://app.response.auckland.ac.nz/e/f2.aspx?elqFormName=EVENTQR&elqSiteID=XXXXXXX&emailAddress=~~eloqua..type--emailfield..syntax--EmailAddress..innerText--EmailAddress..encodeFor--url~~&EventAttendance=Attended">

when the email is delivered there appears to be a QR code as expected but when I decode it looks like maybe the link is too large as it translates to only a portion of the URL

has anyone else experienced this, have another way to capture live event attendance or perhaps have an idea to get around this issue?

I do not believe this can be used for blindform submission. I have tried myself, it didn't work.

By reviewing the googleapis guide on https://developers.google.com/chart/infographics/docs/qr_codes chl=The data to encode. Data can be digits (0-9), alphanumeric characters, binary bytes of data, or Kanji. You cannot mix data types within a QR code. The data must be UTF-8 URL-encoded. Note that URLs have a 2K maximum length, so if you want to encode more than 2K bytes (minus the other URL characters), you will have to send your data using POST.

So it cannot be a URL as it has mixed data types.

Hi have actually since found a workaround for this I am using a query sting in the URL that a form is populating from and our events staff are then able to just click check in

Thanks! The workaround is great! just wondering how come the blindform url is not working but landing page with query string does.

Hi @User_Z5U0D,

Can you please tell me how did you do that?

I have created one Eloqua landing page and connected that with an Eloqua form.

Can you please brief next steps how to capture email address, first name and last name of people who will join my event with just a single click?

@Faye Lu-Oracle, seeking help urgently. If you can also help.

Thanks
