3.1.4: Event registration doesn't find existing Contacts
May 05, 2010, 12:48:23 pm
I upgraded to 3.1.4 just before launching registrations for a new Event.  All online registrations are not syncing to existing Contacts but creating new Contacts.  That is, user fills in their details and a new Civi Contact is created for them rather than updating the exisitng contact details.
This worked on prior versions.  I have not knowingly changed anything else.
Anyone else seen this behaviour or know how to fix?

I've been able to duplicate this error on the demo site with the following actions:

- log on
- create a user
- log off
- register that user for an event

there are now two users, not one

(do a full text search on "lionel" on the demo site and you will see what i did)

Lionel.

Haven't got any responses on this, but as I am able to duplicate in the demo environment (and the bug is causing considerable inconvenience in my current live event registration), I have gone ahead and created an Issue in the system.

It is #6211:  http://issues.civicrm.org/jira/browse/CRM-6211

Would like to help - but as a start, I looked at the fixes that were applied in 3.1.4 and couldn't find any that appear to have modified this code.  Are you aware of any?

yes "lionel" appears to have been deleted now!

1.  I used the drupal one, though my site is joomla.  this shows its core CiviCRM that's at fault?

2.  created the user from the simple "new individual" dialogue on the main admin screen

3.  the event is no longer there, but I picked one that supported Pay Later

I tried it on drupal.demo.civicrm.org and was able to reproduce it :(

would be great if you can check the code and figure out why its not getting the existing contact

the most likely place to check is:

CRM/Event/Form/Registration/Confirm.php, line 968

Code: [Select]
            $dedupeParams = CRM_Dedupe_Finder::formatParams($params, 'Individual');
            $ids = CRM_Dedupe_Finder::dupesByParams($dedupeParams, 'Individual');

basically that should give the ID of the existing contact. it does not, and hence a duplicate is created :(

I can confirm this bug with 3.1.4. and drupal 6.16. I am using Selenium RC to test event registration submissions and for the identical user submitting multiple registrations to the same event, CiviCRM creates multiple contacts in the backend instead of updating the matched contact record. This indicates that the dedupe rules don't get triggered correctly.

This is a big problem that was not present in 3.0.4

I've checked in Confirm.php and there were some recent changes for 3.1.4 but reverting to a prior version of this source file does not fix the error.

There have been no changes in CRM\Dedupe\Finder.php since 3.1.2 which was the last version that I used that did not have this bug

Therefore I think there must be some data corruption happening elsewhere?  Or a bug elsewhere?

Lionel.

you will need to debug and trace the root cause of the error. please keep us updated on your progress

thanx

How do you put a backtrace on a form submission? I think one can add &backtrace=1 to a URL, but within a multi-page form context there is no place I can append this backtrace flag. Do you mean I should add this php function call var_dump(debug_backtrace()); on each consecutive Form template that passes the data along to the next form page?

Is there a global switch I can toggle which will turn on debug_backtrace for all civicrm module page views?

Thanks,

Taiga

Currently dedupe functionality is broken. It fails when there is no logged in user,
Asap we'll fix it and will provide the patch.

thanks for your pointers and updates  :)

Hi there,

is there a canonical method within Jira to get a list of all patches since a minor version release? Right now I discover a bug, search the forums, find a link to Jira and download that patch individually and apply it manually.

Thanks,

Taiga

Fantastic, glad to hear that you know what the problem is and will fix it.

I tried to follow lobo's prompting but haven't had much success debugging this myself - cannot get the php debugger installed successfully  :'(
