One Barcode to populate more than one case properties

Developers

Hii everyone, Is it possible to use one QR code which contains texts to populate several case properties. E.g. after scanning a QR code that contains age, sex, name etc. will populate the respective case properties.

I hope this is clearer.

Yes, that should be possible. What you'd do is make a single barcode question to read the QR code, then have several hidden values to extract each component from the stored text.

For a simple use-case where the QR stores space-separated elements, you could use the selected-at function to get each element by its position.

For anything more complicated, you'd probably want to use json-property. From the example there, if your QR code contained the following JSON:

{
  "full": "New Canada St., 3855 Brienz, Switzerland",
  "geopoint": "46.748107 8.0473685",
  "zipcode": "3855",
  "postcode": "3855",
  "city": "Brienz",
  "region": "Bern",
  "state_long": "Bern",
  "state_short": "CH-BE",
  "country": "Switzerland",
  "country_short": "ch",
  "street": "New Canada St."
}

You could extract the city from your barcode in a hidden value with a calculate expression like

json-property(#form/qr-code, 'city')

and likewise for other properties you wish to save to the case.

I am starting to think that I need to read the release notes! this is a pretty cool function

can you think of other use-cases ?

I believe it was added for a project-specific workflow, but seemed potentially useful to other projects. This application didn't occur to me until reading this forum post, but it seems remarkably useful.
