Contact Summary Hook Implementation

Question

I am trying to add contact created date in contact summary. I am sure that https://docs.civicrm.org/dev/en/latest/hooks/hook_civicrm_summary/ helps the requirement. But I'm not getting how to implement this hook.Any help please?

Answer 1

As already pointed out, the created date is shown on the summary anyway - but since your question is more about using hook_civicrm_summary(), here's an simple example to add the date above the existing summary content:

function demo_civicrm_summary($contactID, &$content, &$contentPlacement) {
  // Lookup 'created_date' for the specified contact
  $dateCreated = civicrm_api3('Contact', 'getValue', array(
    'id' => $contactID, 
    'return' => 'created_date',
  ));  

  // Set $content to what we want to display
  // Can add html with classes for formatting ...
  $content = 'Date created: ' . $dateCreated;

  // Set $contentPlacement to specify where our content is displayed.
  // The default if we don't set this is to display below the existing summary
  $contentPlacement = CRM_Utils_Hook::SUMMARY_ABOVE;
}

Answer 2

The contact created date does show up on Contact Summary page at the bottom of the summary page

If you want as a field to show in summary section then i feel you can use civicrm_summary hook but it would to be very difficult to manipulate where to insert a section in $content as it would be pure html. I would use Buildform and/or Page run hook to add field with some JS to place the field in the page/form.
