From: Andrew Engelbrecht Date: Fri, 15 Sep 2017 20:15:10 +0000 (-0400) Subject: Groups filter hack for smaller groups listings X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=7bb643c0ffbd38d24b840accae1ee99a9249cc8e;p=civicrm-core.git Groups filter hack for smaller groups listings This change is a dirty hack that lets site admins filter the "Contacts Group(s)" field output in select profiles. This reduces overwhem for users when they are making a donation or filling out a form with the Groups signup field. This is preferable to using a custom field with smart groups because the Groups field provides double opt-in, while custom fields do not. The filter is controlled via a json string stored in a drupal variable that can be set with drush like so: drush vset --format=string groups_field_filters "{...}" See the documentation marked with "sudoman hack" in CRM/Contact/Form/Edit/TagsAndGroups.php for an example. --- diff --git a/CRM/Contact/Form/Edit/TagsAndGroups.php b/CRM/Contact/Form/Edit/TagsAndGroups.php index 11bb704fca..ffbd24c860 100644 --- a/CRM/Contact/Form/Edit/TagsAndGroups.php +++ b/CRM/Contact/Form/Edit/TagsAndGroups.php @@ -92,11 +92,73 @@ class CRM_Contact_Form_Edit_TagsAndGroups { if ($groupID || !empty($group)) { $groups = CRM_Contact_BAO_Group::getGroupsHierarchy($ids, NULL, '- ', FALSE, $public); + // sudoman hack begins + // + // This hack allows us to filter Groups listings so users aren't + // overwhelmed with choices.
