Hi team,

how to calculate year month and day from two different date in processmaker 3.1

i have two fields 1) date of joining and second one is date of leaving and this function should be triggered after pressing the calculate button

Hello,

Use below code to get difference:

Code: Select all

$startDate = @@joiningDate;
$endDate = @@leavingDate;
$sDate = strtotime($startDate);
$eDate = strtotime($endDate);
$difference = ($eDate - $sDate) / 86400;   // it will return total no of days

You can use salmon1538's PHP code if needing the difference in days in a trigger. If you want the number of whole days, then use this:

Code: Select all

@@difference = (int) (($eDate - $sDate) / 86400);

If you need to calculate the difference in days between two dates in JavaScript, then you can use the following code:

Code: Select all

function calculateDiff(joinDate, leaveDate) {
  if (joinDate == '' || leaveDate == '') {
    $("#difference").setValue('');
  }
  else {
    var daysDiff = moment(leaveDate).diff(moment(joinDate), 'days')
    $("#difference").setValue(daysDiff);
  }
}

$("#joinDate").setOnchange(function(newVal, oldVal) {
  calculateDiff( newVal, $("#leaveDate").getValue() );
});
    
$("#leaveDate").setOnchange(function(newVal, oldVal) {
  calculateDiff( $("#joinDate").getValue(), newVal );
});

Still curious, where should I input the given code? I have tried to open the variable / formula / sql but couldn't find where did you put the code.
