EXIF data in form

RemcoBr

Hi all,

I am working on a quite simple form in Field Maps and trying to pull EXIF metadata of attached photographs into the form. This would be especially helpful for the date/time of the photographs. I am now using the simple 'Now()' expression, but this would of course return the current time (when one's using the form).

My current expression (see below) returns the correct value when I am designing the form. However, when I am using the Field Maps app on my phone and take a new photograph, an error is returned. Any ideas on what I am doing wrong?

 

 

var features = [];
var att = attachments($feature, {metadata: True});
if (count(att) > 0) {
     for (var a in att) {
          push(features, att[a].exifInfo) 
     }}
//return features;
return features[0][0]['tags'][6]['value'];

Just experimented with this also. It seems that attachments() calls the attachment featureset from the cloud, so current changes are not yet applied and therefore won't appear. But on top of that, even for photos that are already in the cloud, the metadata doesn't contain an exifInfo in my case. It works fine in the popup of the web map, but not in Field Maps. There,

att[a].exifInfo

 evaluates to null.
