Add a date since last update field to a pop-up

[]

This example shows how to add days since the last update for the AGO map viewer popup configuration panel

Use cases

This is designed specifically for the AGO map viewer popup. These set of expressions allow you to represent the number of days since a point or polygon has been udpated.

Workflow

Copy and paste the expression found in the expression template below to the Arcade editor in ArcGIS Online, the relevant location in ArcGIS Pro, or the relevant location in a custom app.

Expression Template

Create an expression to identify the date field and find the

//get the time currently
var timeNow = Date();
//get the time field form your feature layer
var survey = $feature["YOUR_DATE_FIELD_NAME_HERE"];
//get time in hrs, days and use datediff to get the differnce betwen the time now and the time when the layer was updated
var datehrs = Round(DateDiff(survey, timeNow, 'hours'),1);
var datedays = Round(DateDiff(survey, timeNow, 'days'),0);
//display hrs, day or days depending on how long since last updated.
When(
 datehrs < 24, concatenate(datehrs, ' hrs ago'),
 datedays < 2, concatenate(datedays, ' day ago'),
 datehrs >= 48, concatenate(datedays, ' days ago'),
 'error' );

HTML Template

Now add this expression into yoour custom attribute display with the name of your attribute expression. I added the expression to the pop-up title instead so it is displayed more prominently in widgets such as near-me.

last update: {expression/expr["YOUR EXPRESSION NUMBER HERE"]}
