Following updates to PHP 7.3.29 and MySQL 5.7.34 earlier this month, we discovered that discounts are no longer being automatically applied to event registration forms, public or back-end. The discount codes do work when applied manually. No errors are being logged. We just updated CiviDiscount to 3.8.2 from an older version, but that did not resolve the problem. We are on CiviCRM 5.33.5 on Drupal 7.81. Any ideas what might be causing this? Thanks very much.

  • might be worth seeing if you can replicate on dmaster.demo.civicrm.org

  • I did a test on demo and it worked fine. It is also on PHP 7.3.29. I wonder if some other extension we are using might be a factor.

  • This appears of be a version compatibility issue, as price sets that were created before 2018 still display properly. If I copy or try to update an old price set, they stop displaying the discounts.

    I have submitted this as a possible issue with price sets: lab.civicrm.org/dev/core/-/issues/2727

I was able to get this working with this reversal of logic in cividiscount.php: This seems to function properly on CiviDiscount 3.7 on our production server:

- if ($autodiscount) {
-        break;
+ if (!$autodiscount) {
+        continue;

We are still experiencing the puzzling issues mentioned below on our dev server with CiviDiscount 3.8.4. Hopefully someone familiar with the code will be able to work through this and determine what the issue is.

  • I am now noticing some additional strange behavior on our dev server with CiviDiscount 3.8.4. If I go to edit existing discounts from the last few years, the previously selected price sets in the Discounts for Events field are no longer displayed and price sets for events in the last few years no longer appear in the pick list and there are some blank lines instead. I rebooted the server just in case something was hung, and there is no change.
