I have been asked to add some custom fields to the default CiviCRM Interface that bahave like the current employer field.
That is to say, my users want to create certain relationships and have them turn up in the relationships tab.
I had originally implemented this as a contact reference with a filter to look up the specific sub-set of contacts needed but I have been asked to make them relationships.
I realise I can implement this using webforms integration (we are using Drupal 7) but I have been specifically asked to implement this on the default UI.
I have also read it can be achieved using hook_civicrm_post however, I was hoping there was a more straightforward way that I was overlooking so that if in the future one of my users needs to add a new relationship custom field they don't need to update code in an extension
