Field Maps Arcade Expressions

BClaridge

Hi There, I'm new to Field Maps and Arcade expressions. I have done some research and believe I should be able to write an expression to auto populate a field based on the user entry into another field. For example, if the user is collecting a point or line in a particular area which is in a field office- I should be able to auto populate the field office field with the name using some sort of select by location expression.

I could use some help with getting started on the expression...

Something like:

//if point is located in X, then Y. The Field office feature is another hosted layer in the webmap. The field I want to populate is the $feature["ADMIN_ST"] and it has domains...

the popup doesn't display it in Field Maps and only shows the default fields.

Are you configuring the expression and pop-up in the newer Map Viewer? Field Maps doesn't fully support the pop-ups authored by the new Map Viewer (this is under development and planned for this fall). Can you try configuring the pop-up in Map Viewer Classic?

Thanks @Anonymous User, that makes sense. Yes, I had configured that in the new Map Viewer. I've had success doing something similar in Classic, so will just do it there. Is UrlEncode functionality (or similar) available in Map Viewer Classic for customised Pop-Ups? I'm trying to pass across to Survey123 an attribute that contains spaces and ":" characters and I don't believe that they are being parsed correctly into the URL.

I am also having this issue...Field Maps V22.2.0 build 736. This has been my first attempt at creating an Arcade expression in Field Maps, so haven't seen it working in previous versions.

I was trying to create a hyperlink to a Survey123 form using Arcade, but the popup doesn't display it in Field Maps and only shows the default fields.

This is my expression:

var urlsource = 'arcgis-survey123://?itemID=';
var itemID = 'fac53b0e831d46e8a8fd8c18b0afbe5d';
var asset = UrlEncode($feature.Asset);
var asset_ID = UrlEncode($feature.Asset_Description);

var link = urlsource + itemID + "&amp;field:asset=" + asset + "&amp;field:asset_id=" + asset_ID;

var label = '<p><strong>Asset:</strong> ' + $feature.Asset + '<br><br><a href="' + link + '" rel="nofollow ugc noopener noreferrer" target="_blank"><strong>Add Inspection Record</strong></a></p>';

return { 
	type : 'text', 
	text : label
}

It Tests okay and produces the right result, displays as expected in AGOL Map Viewer, just not in Field Maps.

Also tried this simple example...still no joy. Any help appreciated.

return { 
	type : 'text', 
	text : 'This is a thing'
}

Hi Jeff,

Still there is a problem in the new version of Field Maps: the ARCADE expressions defined in Web Map cannot be interpreted by Field Maps!

Hoping one day the Google Street View hyperlink arcade expressions will work in Field Maps?... for now we just get a broken link:

When will this be available? Calculate functionality of fields based on the values of other fields is needed. Thanks

I have a similar expression and didn't know about this bug. Had to delete it so primary operation with Field Maps (linking to survey123) worked properly. I suspect this might be tricky to implement because your querying a layer that may or may not be offline.

Hello Jeff, how is this update going? I thought it was available already based on information found on THIS PAGE, but I cannot get any values to pass into the entry fields in the form based on arcade expressions, so it must only be for showing pop-ups in field maps? The need to pass values into the etnry fields in the form appears to be an in-demand function for a variety of purposes:

How to pass attributes from selected feature into ... - Esri Community

Run Arcade on events - Esri Community

Copy Value from another Layer when creating a new ... - Esri Community

I created the following expression to pass values from an intersecting layer into a newly created point feature in Field Maps, and though it works in pop-ups for already created points, I cannot see a path for me to connect the expression to the field in the Field Maps form to become a permanent attribute value in the dataset:

var intersectLayer =Intersects(FeatureSetByName($map,"Parcels"), $feature)
for (var f in intersectLayer){
return f.legalac+" Acres; "+f.subdivname+" "+f.LEGAL1+" "+F.LEGAL2+" "+F.LEGAL3
}

Hi Jeff,

Thank you for that information. Is there a likely timetable for calculating fields in Field Apps?

I am looking to do some real basic calculations. Such as:

On a Save Event or Attribute Change Event:

if(id > 0)

{

return 1;

}

else

{

return 2;

}

and calculates such as:

if (point_type =='Tree' && species== null)

{

species = 'unknown'

}

Thanks Again,

Scott

Welcome @BClaridge and thank you for your post. Unfortunately this capability is not available yet. With the current support for Arcade expressions in Field Maps, we use the constraint profile and evaluate an expression for the purpose of displaying/not displaying fields. Use of the field calculate profile is on our roadmap and is perhaps the most important smart form feature for us to complete in 2021.

Please let us know what types of calculate expressions you are looking to accomplish. We are looking for examples to help us drive priority of requirements. Thanks!
