No duplicate matching on anonymous event registration
February 22, 2010, 02:33:24 pm
I'm having trouble with anonymous users not getting matched when registering for an event. 

The problem seems similar to this old (and fixed) issue:
http://forum.civicrm.org/index.php/topic,2344.0.html

And the OPPOSITE of this more recent issue:
http://forum.civicrm.org/index.php/topic,10052.0.html

The event has "Allow multiple registrations from the same email address?" set to true and I am using the default strict matching rule (email only, no length set).

Getting the same behavior on the demo site.  The multiple contacts with email address "new@example.com" were all created via event registration.

I'm not certain if this is a bug or if I just don't have something configured correctly.  Any ideas?

on further reflection, i dont think it is a bug for now :)

the docs ask admins to set a stricter matching rule (first/last/email) so that we can create / reuse contacts as needed. Skipping dupe checks basically creates 3 contacts with the same email address which is not great (IMO)

Not sure what the other workarounds are with regard to this. For now, i'd recommend we continue dupe checking with additional partiicpants

I'm a little confused by this.

So if I just change the rule to include first/last dupe checking will occur?  Are you saying that civi looks at the matching rule and only checks for dupes if it contains more than just email?  I assumed it would use the matching rule to check for dupes and that I could adjust how strict it was to fit my needs.

3 contacts?  I am only getting 1 dupe (a second contact with the same email) for each registration.

So dupe checking is happening now or not?

1. dupe checking is happening NOW. The proposed fix which was committed was to turn it off, which i dont think is right

2. In addition to email if you also collect first name / last name and change the strict dupe check to include the first name, last name AND email fields things should function properly (assuming u dont have 2 different people with the same first/last/email)

3. we'll fix and improve the docs to clarify things

My O.P. was that it does NOT appear to be happening now, neither on my install nor the demo.

On the demo, I created a test event.  I also checked that the default strict individual matching rule was for email only.

I logged out and registered for the event as new@example.com.  A new contact was created as expected.  Then I registered for the same event again using the same email address new@example.com.  A second, duplicate contact was created.

If dupe checking was happening now, the rule should have triggered a match and a second participant record should have been created for the first contact.  Instead, a duplicate contact was created.

I have not installed/tested the patch, but turning off dupe checking was not what I originally intended.

Understood.  But it should also work with just email address matching if that's all I need, right?

UPDATE

Matching seems to be working fine when registering for live event I have with required CC payment -- had a couple sales last night and they matched existing contacts.  But for a test event I am playing with I get duplicate contacts with every registration.

And to reiterate: This is only with anonymous users and I saw the same behavior on the demo site.

Things that are different about the test event:
1. Event is not public
2. No payment processor
3. Pay later enabled
4. No Confirmation email sent

As mentioned by lobo, you should change your strict to email / first / last name and then collect first / last / email for additional participant.

Really?  This just doesn't make sense to me.

If the default strict rule is for email only, this is a less restrictive rule which should mean more matches and fewer duplicates.  Why would making the rule more restrictive (email/first/last) result in more matches?

If the rule is email only, it should generate a match whenever the email address matches.  This does not work.  Changing the rule to match on name seems to be more of a work around than a fix or explanation.

Any progress on this? I'm having the same problem for anonymous users. I get duplicate contact records if two users register using the same e-mail address. The event is a free event (no fees). Both the "Register multiple participants?" and "Allow multiple registrations from the same email address" options are unchecked.
