Drupal 7, CiviCRM 5.10

I'd like to send out an "update details" email to contacts - a profile with checksum. It will include some other custom field questions but i want to be alerted specifically if the general contact fields are updated - Address, phone number etc.

I can put those who completed the profile into a group but that won't distinguish between those changed and those whose contact details remain the same..

I don't think i can create a duplicate to dedupe later if using checksum?

The only other idea i had is to have two profiles - one for my custom field questions and another for "change contact details" and rely on contacts only submitting that form if things have been altered - Even then it would be useful to know which field specifically had changed but perhaps that's my only option?

If you have hosting that allows you to turn on Detailed Logging, there are two extensions that provide address history. One is in Extended Reports; the other is Joseph Lacey's Address Log report. It should be relatively simple to extend either one to support phone/email/etc.

Another option, low-tech but effective, would be to export the contact details ahead of time, then export again after folks have filled things out. Paste the two spreadsheets into one and use a simple formula. E.g. if old email is in column C and new email in column H, =IF(C1 != H1, "Changed", "") in a new column will label any records where the email changed.

  • Thanks, i'll check those out. I have actually managed to go this long without being aware of detailed logging at all and combined with the address log report i think i should be able to get something that does what i need, pretty much. Apr 9, 2019 at 15:44

I think you can achieve your goal using webforms. It may require a bit of jquery or could possibly be done just with Conditionals. I suspect the latter would require a read-only field 'showing' the data, and another field for the change. Then a conditional that says eg 'if A != B then set value to 'insert email address'. then set up a mailing on that basis.

i am possibly oversimplifying this but would be a route i would check.
