I've got the request to display (certain) groups in the membership detail report. A lot has been written over time about customizing reports, and I'm not sure what info is up-to-date. This looks good: https://alastaira.wordpress.com/2011/03/17/civicrm-creating-a-custom-report/
I think roughly, I would need to
- set up the paths for custom templates and php files at setting/path
- create a custom template with just a single {include file="CRM/Report/Form.tpl"}
- create a custom php file copied from CRM/Report/Form/Member/Detail.php
- register both using Administer –> CiviReport –> Manage Templates
- in the php file, append stuff to _columns and from()
is that correct ? Has anyone already done something like this for groups .. ?
